The ''GRASS Community Meeting'' for contributors and developers will be happening from '''July 11 - 19, 2026''' in [https://www.openstreetmap.org/relation/46990#map=12/46.1349/11.1947 San Michele all'Adige, Trentino, Italy].

== Sponsors ==

Sponsors make the event possible. Learn more about [https://grass.osgeo.org/contribute/sponsoring/ Sponsoring].

* [https://www.osgeo.org/ OSGeo]: 2500 USD (see [https://wiki.osgeo.org/w/index.php?title=GRASS_Community_Meeting_2026:_Budget budget]]).

[[File:Osgeo logo.png|none|left|alt=Light and dark green logo of OSGeo saying Your Open Source Compass|Open Source Geospatial Foundation]]

== Purpose ==
The ''GRASS Community Meeting'' is a great occasion for folks to support the development by actively contributing to the project in different ways. These include source code updates, documentation (manuals, wiki, tutorials), translations, website improvements or likewise. The community meeting is also a get-together where supporters, contributors, power users and developers make decisions and tackle larger problems related to the project, discuss and collaboratively resolve bugs, plan the direction for the project and work on new features. We welcome people committed to improving the GRASS project and the interfaces to QGIS, GDAL, PostGIS, R, OGC Services and others.

The focus is on GRASS maintenance, and interaction with other projects. Many maintenance tasks, infrastructure changes, and planning of large changes especially benefits from maintainers being in one place and time zone. While the specific topics highly depend on the participants, we will prioritize topics which require highly synchronous collaboration, such as the CMake build system transition and API transitions. The [https://grass.osgeo.org/news/2025_05_27_grass_dev_summit_report/ 2025 event report] gives an overview of what was achieved last year.

We do require participants to work on GRASS or connections to other projects. However, we leave them the freedom to work on what they think is the best contribution to the project given their skills and time available.

Registration is free; participants cover their own travel and lodging, often with employer support — thank you. Ideally we'd reimburse everyone, and every [https://numfocus.org/donate-to-grass donation] or [https://grass.osgeo.org/contribute/sponsoring/ employer sponsorship] of the project helps us get closer.

== Venue ==
The meeting will be hosted at [https://fmach.it/ Fondazione Edmund Mach] (FEM) in San Michele all'Adige, Trentino, Italy — about 15 km north of Trento. FEM is a research and education center with on-site facilities that allow participants to work, sleep, and eat in the same location.

[https://maps.app.goo.gl/5YEuEts6qXvky7HD9 Map]

=== Getting there ===

San Michele all'Adige is reachable by train on the Trento–Bolzano line (San Michele all'Adige–Mezzocorona station), with frequent connections from Trento (~15 minutes) and Verona (~1 hour). The nearest airports are Verona (VRN), Venice Marco Polo (VCE) and Treviso (TSF), Milan Bergamo (BGY), Malpensa (MXP), and Linate (LIN), Bologna (BLQ), and Innsbruck (INN) in Austria. Trento is also the host city of FOSS4G Italy 2026 (July 9–11), making it convenient to combine both events.

== Accommodation and Costs ==

''Registration is free''. However, participants should plan for the following costs:

* Travel
* Lodging

Participants can stay on-site at the FEM convitto (dormitory), keeping the community together for the full duration of the meeting:

* €35 per person per night
* Double and triple rooms (triples include a small kitchen)
* A mandatory on-site supervisor is required at €200 per night (flat fee, shared across the group)
* Family members are welcome to stay in the dormitory as well
* [https://cif.fmach.it/content/download/2701/78358/file/brochure_convitto.pdf Brochure]
* Details to be communicated soon.

For anyone preferring alternative lodging, hotels and B&Bs are available in San Michele and nearby Trento.

Lunches on weekdays can be taken at the FEM canteen (mensa), located on the same campus. Details and pricing are being finalized.

== Individual Preparation ==

* Bring your own computer
* Bring {{wikipedia|AC power plugs and sockets|power adapter}} if needed (Italy: 230V, 50Hz, {{wikipedia|Europlug|Type C}}, {{wikipedia|Schuko|Type F}}, and {{wikipedia|AC power plugs and sockets: L|Type L}} sockets are common)
* Install git and the compiler tools, and come with a working GRASS development environment if possible. See [https://github.com/OSGeo/grass/blob/main/CONTRIBUTING.md here] for details.

== FAQ ==

* ''Is this a conference?''
** Talks or presentations may be included, but the purpose is to work together on the project. Among conference formats, the closest comparison would be a participatory workshop.
* ''Is this a hackathon?''
** While there is plenty of intensive coding, the meeting is not competitive. We meet to collaborate.
* ''Is the GRASS Community Meeting for developers only?''
** No, the meeting is open to all users, supporters, contributors, power users, and developers ''who want to make a meaningful contribution to the project''.
* ''What skills do I need?''
** Coding skills are not required. Contributions to documentation, tutorials, translations, website, and testing are all valuable. Practical help during the meeting, such as coordinating meals, photography, or reporting, is a real contribution too.
* ''Can I attend remotely?''
** The meeting is in-person, but everyone is welcome to use the same week for focused work on the project from wherever they are.
* ''What language is used during the meeting?''
** English is the working language, but you may hear several other languages spoken at the event.
* ''How was it last time?''
** Splendid! See [[GRASS Developer Summit Raleigh 2025]]!
* ''Where can I get help and more information about the community meeting?''
** Contact local organizer [[User:Lucadelu|Luca Delucchi]] (<tt><lucadeluge at gmail com></tt>) or [[User:wenzeslaus|Vaclav Petras]] (<tt><wenzeslaus at gmail com></tt>) for budget questions.
* ''What if I can't spend time on this?''
** Can you spend money instead? [https://numfocus.org/donate-to-grass Donate to GRASS through NumFOCUS] to help keep the project going.

== Purpose ==
The ''GRASS Community Meeting'' is a great occasion for folks to support the development by actively contributing to the project in different ways. These include source code updates, documentation (manuals, wiki, tutorials), translations, website improvements or likewise. The community meeting is also a get-together where supporters, contributors, power users and developers make decisions and tackle larger problems related to the project, discuss and collaboratively resolve bugs, plan the direction for the project and work on new features. We welcome people committed to improving the GRASS project and the interfaces to QGIS, GDAL, PostGIS, R, OGC Services and others.

The focus is on GRASS maintenance, and interaction with other projects. Many maintenance tasks, infrastructure changes, and planning of large changes especially benefits from maintainers being in one place and time zone. While the specific topics highly depend on the participants, we will prioritize topics which require highly synchronous collaboration, such as the CMake build system transition and API transitions. The [https://grass.osgeo.org/news/2025_05_27_grass_dev_summit_report/ 2025 event report] gives an overview of what was achieved last year.

We do require participants to work on GRASS or connections to other projects. However, we leave them the freedom to work on what they think is the best contribution to the project given their skills and time available.

Registration is free; participants cover their own travel and lodging, often with employer support — thank you. Ideally we'd reimburse everyone, and every [https://numfocus.org/donate-to-grass donation] or [https://grass.osgeo.org/contribute/sponsoring/ employer sponsorship] of the project helps us get closer.

== Venue ==
The meeting will be hosted at [https://fmach.it/ Fondazione Edmund Mach] (FEM) in San Michele all'Adige, Trentino, Italy — about 15 km north of Trento. FEM is a research and education center with on-site facilities that allow participants to work, sleep, and eat in the same location.

[https://maps.app.goo.gl/5YEuEts6qXvky7HD9 Map]

=== Getting there ===

San Michele all'Adige is reachable by train on the Trento–Bolzano line (San Michele all'Adige–Mezzocorona station), with frequent connections from Trento (~15 minutes) and Verona (~1 hour). The nearest airports are Verona (VRN), Venice Marco Polo (VCE) and Treviso (TSF), Milan Bergamo (BGY), Malpensa (MXP), and Linate (LIN), Bologna (BLQ), and Innsbruck (INN) in Austria. Trento is also the host city of FOSS4G Italy 2026 (July 9–11), making it convenient to combine both events.

== Accommodation and Costs ==

''Registration is free''. However, participants should plan for the following costs:

* Travel
* Lodging

Participants can stay on-site at the FEM convitto (dormitory), keeping the community together for the full duration of the meeting:

* €35 per person per night
* Double and triple rooms (triples include a small kitchen)
* A mandatory on-site supervisor is required at €200 per night (flat fee, shared across the group)
* Family members are welcome to stay in the dormitory as well
* [https://cif.fmach.it/content/download/2701/78358/file/brochure_convitto.pdf Brochure]
* Details to be communicated soon.

For anyone preferring alternative lodging, hotels and B&Bs are available in San Michele and nearby Trento.

Lunches on weekdays can be taken at the FEM canteen (mensa), located on the same campus. Details and pricing are being finalized.

== Individual Preparation ==

* Bring your own computer
* Bring {{wikipedia|AC power plugs and sockets|power adapter}} if needed (Italy: 230V, 50Hz, {{wikipedia|Europlug|Type C}}, {{wikipedia|Schuko|Type F}}, and {{wikipedia|AC power plugs and sockets: L|Type L}} sockets are common)
* Install git and the compiler tools, and come with a working GRASS development environment if possible. See [https://github.com/OSGeo/grass/blob/main/CONTRIBUTING.md here] for details.

== FAQ ==

* ''Is this a conference?''
** Talks or presentations may be included, but the purpose is to work together on the project. Among conference formats, the closest comparison would be a participatory workshop.
* ''Is this a hackathon?''
** While there is plenty of intensive coding, the meeting is not competitive. We meet to collaborate.
* ''Is the GRASS Community Meeting for developers only?''
** No, the meeting is open to all users, supporters, contributors, power users, and developers ''who want to make a meaningful contribution to the project''.
* ''What skills do I need?''
** Coding skills are not required. Contributions to documentation, tutorials, translations, website, and testing are all valuable. Practical help during the meeting, such as coordinating meals, photography, or reporting, is a real contribution too.
* ''Can I attend remotely?''
** The meeting is in-person, but everyone is welcome to use the same week for focused work on the project from wherever they are.
* ''What language is used during the meeting?''
** English is the working language, but you may hear several other languages spoken at the event.
* ''How was it last time?''
** Splendid! See [[GRASS Developer Summit Raleigh 2025]]!
* ''Where can I get help and more information about the community meeting?''
** Contact local organizer [[User:Lucadelu|Luca Delucchi]] (<tt><lucadeluge at gmail com></tt>) or [[User:wenzeslaus|Vaclav Petras]] (<tt><wenzeslaus at gmail com></tt>) for budget questions.
* ''What if I can't spend time on this?''
** Can you spend money instead? [https://numfocus.org/donate-to-grass Donate to GRASS through NumFOCUS] to help keep the project going.

[[File:Osgeo logo.png|none|left|alt=Light and dark green logo of OSGeo saying Your Open Source Compass|Open Source Geospatial Foundation]]

== Purpose ==
The ''GRASS Community Meeting'' is a great occasion for folks to support the development by actively contributing to the project in different ways. These include source code updates, documentation (manuals, wiki, tutorials), translations, website improvements or likewise. The community meeting is also a get-together where supporters, contributors, power users and developers make decisions and tackle larger problems related to the project, discuss and collaboratively resolve bugs, plan the direction for the project and work on new features. We welcome people committed to improving the GRASS project and the interfaces to QGIS, GDAL, PostGIS, R, OGC Services and others.

The focus is on GRASS maintenance, and interaction with other projects. Many maintenance tasks, infrastructure changes, and planning of large changes especially benefits from maintainers being in one place and time zone. While the specific topics highly depend on the participants, we will prioritize topics which require highly synchronous collaboration, such as the CMake build system transition and API transitions. The [https://grass.osgeo.org/news/2025_05_27_grass_dev_summit_report/ 2025 event report] gives an overview of what was achieved last year.

We do require participants to work on GRASS or connections to other projects. However, we leave them the freedom to work on what they think is the best contribution to the project given their skills and time available.

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

=== Mentoring Activities ===
Mentors were actively working with 3 mentees.

=== Documentation and Tutorials ===
We finalized and prepared for launch Quarto-based tutorial website editable through GitHub. OSGeo provided a new domain [https://grass-tutorials.osgeo.org/ grass-tutorials.osgeo.org]. Initial set of tutorials were created by Veronica Andreo when she was part of the NSF POSE team (some tutorials will be finalized and released later). Anna Petrasova did the reviews, curation, posts for external tutorials, and transition from list of tutorials at the main website.

We did a major push to create Markdown files in the source code and enable the compilation of documentation for mkdocs. We also configured the mkdocs and revised the Markdown syntax in the files.

=== Communication and outreach ===

Renewed [https://www.youtube.com/@grass-gis Youtube channel @grass-gis] by adding playlists, organizing videos, and updating branding.

=== Brand ===

New branding concept (new logo, rename from "GRASS GIS" to "GRASS") presented to PSC by Vaclav Petras. The rebranding was led by Vaclav Petras, with Sarah White as lead designer, Corey White on website and documentation front-end development, and Anna Petrasova providing key feedback and review. The name GRASS was adopted by the PSC in a motion initiated by Vaclav Petras.

=== Governance ===
Submitted application for GRASS GIS to join NumFocus.

=== Event Planning and Organizing ===

* Created draft of schedule, agenda, and budget.
* Identified participants eligible for travel support.
** While the meeting is open to anyone, the NSF-funded travel support is based on priorities set in the NSF POSE project for the Developer Summit.
** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

== AI Tool Usage Policy ==
We acknowledge that applicants may use AI tools (like ChatGPT, Copilot, etc.) to assist with proposal writing and coding. However:

* Your proposal should reflect your own understanding and voice. AI-generated "slop" (overly generic or regurgitated content) is easy to spot and will hurt your application.
* We evaluate applications primarily on GitHub contributions and communication with the GRASS community, not just proposal polish.
* Show us you understand the project through high-quality pull requests on GitHub.
* Disclose AI usage: If you use AI tools in your proposal or code contributions, please disclose the extent to which you used them (e.g., for brainstorming, proofreading, code suggestions, etc.).

== Ideas ==
If you are a student you can suggest a new idea or pick up an existing one. In any case write about it to [https://discourse.osgeo.org/c/grass/developer/61 OSGeo Discourse forum for GRASS developers], [https://github.com/OSGeo/grass/discussions GitHub Discussions], or [https://gitter.im/grassgis/community Gitter].

You are invited as well to have a close look at ideas from previous years ([https://trac.osgeo.org/grass/wiki/GSoC/2014 2014], [https://trac.osgeo.org/grass/wiki/GSoC/2015 2015], [https://trac.osgeo.org/grass/wiki/GSoC/2016 2016],

=== Parallelization of existing tools ===

There are several tools that would benefit from parallelization with OpenMP, e.g. r.texture, r.fill.stats, r/v.surf.idw, r.viewshed, v.to.rast, r.grow.distance, v.surf.bspline, r.proj, ...
For overview of current state, see [[Raster_Parallelization_with_OpenMP]].

* Requirements: familiarity with C, OpenMP
* Mentor: Huidae Cho
* Co-mentor: Vaclav Petras, Anna Petrasova
* Project length: Large (350 hours)
* Rating: difficult
* Expected Outcomes: parallelized 2-5 tools, depending on complexity
* Test of skills (one or more):
** Address https://github.com/OSGeo/grass/issues/5776 (carefully read the existing conversation in the issue and linked PR)
** Pick a tool and develop prototype implementation of the parallelization.

=== Improve GRASS user experience in Jupyter Notebook ===
[[File:Jupyter_interactive_viewshed.png|500px|thumb|right|InteractiveMap in grass.jupyter library]]
Python package [https://grass.osgeo.org/grass-stable/manuals/libpython/grass.jupyter.html grass.jupyter] was developed during [https://trac.osgeo.org/grass/wiki/GSoC/2021/JupyterAndGRASS GSoC 2021] to simplify running GRASS from Jupyter Notebooks and displaying data. This project could focus on adding features such as better symbology handling and adding legend to InteractiveMap and better integration with matplotlib.

* Requirements: Python
* Mentor: Anna Petrasova
* Co-mentor: Vaclav Petras, Helena Mitasova, Corey White
* Project length: Large (350 hours)
* Rating: easy to medium
* Expected Outcomes: improved user experience when using GRASS through notebooks
* Test of skills: write a test for [https://github.com/OSGeo/grass/tree/main/python/grass/jupyter grass.jupyter library] using python unittest or pytest, more info [https://grass.osgeo.org/grass-devel/manuals/libpython/gunittest_testing.html here] or rewrite some of the functions in grass.jupyter library using the new [https://grass.osgeo.org/grass-devel/manuals/python_intro.html#running-tools Tools API].

=== Add JSON output to different tools ===
There are several tools in GRASS that would benefit from a JSON-formatted output.
Besides adding the JSON output, the work would also include adding tests and basic documentation.
* Requirements: C, Python
* Mentor: Vaclav Petras
* Co-mentor: Anna Petrasova, Corey White
* Project length: Large (350 hours)
* Rating: easy to medium
* Expected Outcomes: 10-20 tools (depending on project length and complexity of the tool) tools with well tested JSON output
* Note: A lot of work on JSON was already done, but there is more! Some of the remaining tools require more design. There are also Python tools (not just C which was the focus previously) and then also the grass-addons repo. Some tools also don't have any machine readable output right now and should. Also current tools which use other tools should use the new JSON as opposed to what they are using now. Preparing a well-reasoned list of tasks is a part of the application.
* Test of skills (pick one or more):
** https://github.com/OSGeo/grass/issues/6968
** https://github.com/OSGeo/grass/issues/6969
** https://github.com/OSGeo/grass/issues/6970

=== Support writing tests with pytest ===

* The current testing framework, ''[https://grass.osgeo.org/grass-stable/manuals/libpython/gunittest.html grass.gunittest]'', was written before migration to Git/GitHub and when long free runs in 3rd party services were unthinkable. Additionally, some no longer relevant goals were prioritized, such as independence on the current code, detailed custom HTML reports, success tracking over time, and high specialization towards GRASS-specifics.
* ''grass.gunittest'' is based on Python ''unittest'' package and many projects since then migrated to //pytest//, e.g., GDAL and Numpy. While ''unittest'' is inspired by Java's JUnit, ''pytest'' is designed to support writing small, readable tests, and uses plain `assert` statements instead of many different assert methods.
* Using ''pytest'' should lead to tests which feel more like Python scripts and to minimum of testing-specific code.
* An example issue of ''grass.gunittest'' is that it doesn't work well with tests of the main GRASS executable (prominence of `grass ... --exec` is yet another new thing which changed since ''grass.gunittest'' was designed).
* Two main things needed:
** Create general comparison functions from the ''grass.gunittest'' assert methods so that they can be used with pytest.
** Current grass.script.setup.init function and grass.script.core.create_location function don't work well in the context of a pytest test function. More
* Additional things needed:
** Fixture for pytest to set up and tear down a GRASS session in a temporary mapset.

* Requirements: Python
* Project length: Large (350 hours)
* Mentor: Vaclav Petras
* Co-mentor: Stefan Blumentrath
* Proposed by: Vaclav Petras
* Rating: easy to medium
* Expected Outcomes: Convenient way of writing tests with pytest
* Test of skills: Fix failing tests and/or write new tests (more is better). Alternatively, addressing a smaller problem in the testing framework is a good task, too.

=== Fix known code defects ===

* Fix code defects (security or code quality) such as those reported by Coverity Scan.
* Mentors: Vaclav Petras
* Co-mentors: ?
* Proposed by: Vaclav Petras
* Project length: Large (350 hours)

=== Subcommand CLI for GRASS ===

* Make running of GRASS tools in command line as easy as possible.
** `grass run r.slope.aspect elevation=elevation.tiff slope=slope.tiff aspect=aspect.tiff`
* Project length: Large (350 hours)
* Rating: medium
* Requirements:
** Language: Python
** Proposal: Student needs to show sufficient understanding of data and project handling in GRASS. Furthermore, the proposal needs to present, at least, concrete formulation of ideas, identification of missing and existing parts, and new subcommands.
* Mentors: Vaclav Petras
* Co-mentors: Stefan Blumentrath, Corey White
* Proposed by: Vaclav Petras
* Expected outcomes:
** A subcommand which runs a GRASS tool on GeoTiff and GeoPackage in one step.
** A complete parity with the existing CLI.
** An underlying Python API which will be used to implement the CLI.
* Test and training tasks (complete one or more): Add a subcommand, sub-subcommand, or an option to the experimental interface (with tests).
** Add `--region` to set a temporary computational region for the execution, e.g. `--region="raster=raster_name"`.
** Add `--import-raster=some/file.tiff` which imports (r.import) a raster file (same for vector and similarly for export).
** Add `--link-raster=some/file.tiff` which links (r.external) a raster file (same for vector and similarly for r.external.out).

Current state:

# Reveals the existing subcommands
PYTHONPATH=$(grass --config python-path) python -m grass.app --help
# Allows running subset of commands
grass run --help


=== GUI: Add space-time datasets support in Data Catalog ===
[[File:GUI_data_tab.png|400px|thumb|right|Data catalog]]
Currently GRASS Data Catalog shows only raster and vector maps. The goal of this project is to add support for space-time datasets. It is mainly space-time raster datasets. In the next phase of the project support for other types of space-time datasets (vector and 3D raster) could be added. Besides displaying space-time datasets in the layer tree, it is also about adding the equivalent functionality currently available for raster and vector layers from the context menu.

* Requirements: familiar with Python
* Project length: Large (350 hours)
* Mentor: Martin Landa
* Co-mentor: Anna Petrasova
* Proposed by: Martin Landa
* Rating: medium
* Expected Outcomes: 175 hours basic support for space-time raster datasets; 350 extended support also for other space-time datasets types (vector, 3D raster)
* Test of skills:
** suggest/implement solution for completing https://github.com/OSGeo/grass/issues/2599

=== Searchable metadata in Space Time Datasets ===
The temporal framework in GRASS was initially developed almost 15 years ago. Spatio-temporal data has become more widely available since then and new standards emerged like e.g. ''[https://docs.ogc.org/cs/25-004/25-004.html STAC]'' with ''[https://github.com/stac-extensions/stac-extensions.github.io extensions]'', or the ''[https://cfconventions.org/ CF-conventions]''. The aim of this project is to extend the metadata model in the temporal framework to improve discoverability of map datasets registered in TGIS and to allow users to embed extended metadata with the registered maps in a Space Time Dataset in a searchable way. Ideally, the new model is able to account for the standards mentioned above.

*** allows to use metadata in temporal_where to select relevant elements of Space time datasets
** updated tool to create space time datasets (t.create) in the TGIS database with extended metadata
** updated tool to register map datasets (t.register) in the TGIS database with extended metadata
** Conversion tool for database Upgrades (v3 to v4)
** a new tool to update / modify metadata in the TGIS database
** Storage of timeseries metadata for both C-based and temporal Tools

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

=== Mentoring Activities ===
Mentors were actively working with 3 mentees.

=== Documentation and Tutorials ===
We finalized and prepared for launch Quarto-based tutorial website editable through GitHub. OSGeo provided a new domain [https://grass-tutorials.osgeo.org/ grass-tutorials.osgeo.org]. Initial set of tutorials were created by Veronica Andreo when she was part of the NSF POSE team (some tutorials will be finalized and released later). Anna Petrasova did the reviews, curation, posts for external tutorials, and transition from list of tutorials at the main website.

We did a major push to create Markdown files in the source code and enable the compilation of documentation for mkdocs. We also configured the mkdocs and revised the Markdown syntax in the files.

=== Communication and outreach ===

Renewed [https://www.youtube.com/@grass-gis Youtube channel @grass-gis] by adding playlists, organizing videos, and updating branding.

=== Brand ===

New branding concept (new logo, rename from "GRASS GIS" to "GRASS") presented to PSC by Vaclav Petras. The rebranding was led by Vaclav Petras, with Sarah White as lead designer, Corey White on website and documentation front-end development, and Anna Petrasova providing key feedback and review. The name GRASS was adopted by the PSC in a motion initiated by Vaclav Petras.

=== Governance ===
Submitted application for GRASS GIS to join NumFocus.

=== Event Planning and Organizing ===

* Created draft of schedule, agenda, and budget.
* Identified participants eligible for travel support.
** While the meeting is open to anyone, the NSF-funded travel support is based on priorities set in the NSF POSE project for the Developer Summit.
** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

=== Documentation and Tutorials ===
We finalized and prepared for launch Quarto-based tutorial website editable through GitHub. OSGeo provided a new domain [https://grass-tutorials.osgeo.org/ grass-tutorials.osgeo.org]. Initial set of tutorials were created by Veronica Andreo when she was part of the NSF POSE team (some tutorials will be finalized and released later). Anna Petrasova did the reviews, curation, posts for external tutorials, and transition from list of tutorials at the main website.

We did a major push to create Markdown files in the source code and enable the compilation of documentation for mkdocs. We also configured the mkdocs and revised the Markdown syntax in the files.

=== Communication and outreach ===

Renewed [https://www.youtube.com/@grass-gis Youtube channel @grass-gis] by adding playlists, organizing videos, and updating branding.

=== Brand ===

New branding concept (new logo, rename from "GRASS GIS" to "GRASS") presented to PSC by Vaclav Petras. The rebranding was led by Vaclav Petras, with Sarah White as lead designer, Corey White on website and documentation front-end development, and Anna Petrasova providing key feedback and review. The name GRASS was adopted by the PSC in a motion initiated by Vaclav Petras.

=== Governance ===
Submitted application for GRASS GIS to join NumFocus.

=== Event Planning and Organizing ===

* Created draft of schedule, agenda, and budget.
* Identified participants eligible for travel support.
** While the meeting is open to anyone, the NSF-funded travel support is based on priorities set in the NSF POSE project for the Developer Summit.
** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

=== NSF I-Corps program ===
Corey White, Vaclav Petras, and Anna Petrasova participated in a 4-week long intensive mandatory training that draws on the methods, customer discovery, and curriculum of the [https://new.nsf.gov/funding/initiatives/i-corps NSF Innovation Corps] and applies them to open-source projects.

The program included conducting 70+ 30-minute interviews with both GRASS users and non-users to better shape the future path of GRASS GIS and the POSE project. So far, the interviews focused on educators, companies, researchers, influencers and it focused more on non-users than users.

Next steps, include processing the collected qualitative data, developing possible future directions for sustainability of the project, discussing these with the Project Steering Committee, the core team of developers, and the broader community.

=== Mentoring Program ===
The development oriented [https://grass.osgeo.org/news/2023_10_11_mentoring_program_announced/ mentoring program] welcomed 5 new participants from various institutions including universities, USGS, US Army Corps of Engineers, and local municipalities. The discussed topics covered developing workflows for topography and network analysis, environmental modeling, and geophysics. Participants were supported by email and video calls.

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

=== Documentation and Tutorials ===
We finalized and prepared for launch Quarto-based tutorial website editable through GitHub. OSGeo provided a new domain [https://grass-tutorials.osgeo.org/ grass-tutorials.osgeo.org]. Initial set of tutorials were created by Veronica Andreo when she was part of the NSF POSE team (some tutorials will be finalized and released later). Anna Petrasova did the reviews, curation, posts for external tutorials, and transition from list of tutorials at the main website.

We did a major push to create Markdown files in the source code and enable the compilation of documentation for mkdocs. We also configured the mkdocs and revised the Markdown syntax in the files.

=== Communication and outreach ===

Renewed [https://www.youtube.com/@grass-gis Youtube channel @grass-gis] by adding playlists, organizing videos, and updating branding.

=== Brand ===

New branding concept (new logo, rename from "GRASS GIS" to "GRASS") presented to PSC by Vaclav Petras. The rebranding was led by Vaclav Petras, with Sarah White as lead designer, Corey White on website and documentation front-end development, and Anna Petrasova providing key feedback and review. The name GRASS was adopted by the PSC in a motion initiated by Vaclav Petras.

=== Governance ===
Submitted application for GRASS GIS to join NumFocus.

=== Event Planning and Organizing ===

* Created draft of schedule, agenda, and budget.
* Identified participants eligible for travel support.
** While the meeting is open to anyone, the NSF-funded travel support is based on priorities set in the NSF POSE project for the Developer Summit.
** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

=== Documentation and Tutorials ===
We finalized and prepared for launch Quarto-based tutorial website editable through GitHub. OSGeo provided a new domain [https://grass-tutorials.osgeo.org/ grass-tutorials.osgeo.org]. Initial set of tutorials were created by Veronica Andreo when she was part of the NSF POSE team (some tutorials will be finalized and released later). Anna Petrasova did the reviews, curation, posts for external tutorials, and transition from list of tutorials at the main website.

We did a major push to create Markdown files in the source code and enable the compilation of documentation for mkdocs. We also configured the mkdocs and revised the Markdown syntax in the files.

=== Communication and outreach ===

Renewed [https://www.youtube.com/@grass-gis Youtube channel @grass-gis] by adding playlists, organizing videos, and updating branding.

=== Brand ===

New branding concept (new logo, rename from "GRASS GIS" to "GRASS") presented to PSC by Vaclav Petras. The rebranding was led by Vaclav Petras, with Sarah White as lead designer, Corey White on website and documentation front-end development, and Anna Petrasova providing key feedback and review. The name GRASS was adopted by the PSC in a motion initiated by Vaclav Petras.

=== Governance ===
Submitted application for GRASS GIS to join NumFocus.

=== Event Planning and Organizing ===

* Created draft of schedule, agenda, and budget.
* Identified participants eligible for travel support.
** While the meeting is open to anyone, the NSF-funded travel support is based on priorities set in the NSF POSE project for the Developer Summit.
** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

=== Documentation and Tutorials ===
We finalized and prepared for launch Quarto-based tutorial website editable through GitHub. OSGeo provided a new domain [https://grass-tutorials.osgeo.org/ grass-tutorials.osgeo.org]. Initial set of tutorials were created by Veronica Andreo when she was part of the NSF POSE team (some tutorials will be finalized and released later). Anna Petrasova did the reviews, curation, posts for external tutorials, and transition from list of tutorials at the main website.

We did a major push to create Markdown files in the source code and enable the compilation of documentation for mkdocs. We also configured the mkdocs and revised the Markdown syntax in the files.

=== Communication and outreach ===

Renewed [https://www.youtube.com/@grass-gis Youtube channel @grass-gis] by adding playlists, organizing videos, and updating branding.

=== Brand ===

New branding concept (new logo, rename from "GRASS GIS" to "GRASS") presented to PSC by Vaclav Petras. The rebranding was led by Vaclav Petras, with Sarah White as lead designer, Corey White on website and documentation front-end development, and Anna Petrasova providing key feedback and review. The name GRASS was adopted by the PSC in a motion initiated by Vaclav Petras.

=== Governance ===
Submitted application for GRASS GIS to join NumFocus.

=== Event Planning and Organizing ===

* Created draft of schedule, agenda, and budget.
* Identified participants eligible for travel support.
** While the meeting is open to anyone, the NSF-funded travel support is based on priorities set in the NSF POSE project for the Developer Summit.
** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

=== Mentoring Activities ===
Mentors were actively working with 3 mentees.

=== Documentation and Tutorials ===
We finalized and prepared for launch Quarto-based tutorial website editable through GitHub. OSGeo provided a new domain [https://grass-tutorials.osgeo.org/ grass-tutorials.osgeo.org]. Initial set of tutorials were created by Veronica Andreo when she was part of the NSF POSE team (some tutorials will be finalized and released later). Anna Petrasova did the reviews, curation, posts for external tutorials, and transition from list of tutorials at the main website.

We did a major push to create Markdown files in the source code and enable the compilation of documentation for mkdocs. We also configured the mkdocs and revised the Markdown syntax in the files.

=== Communication and outreach ===

Renewed [https://www.youtube.com/@grass-gis Youtube channel @grass-gis] by adding playlists, organizing videos, and updating branding.

=== Brand ===

New branding concept (new logo, rename from "GRASS GIS" to "GRASS") presented to PSC by Vaclav Petras. The rebranding was led by Vaclav Petras, with Sarah White as lead designer, Corey White on website and documentation front-end development, and Anna Petrasova providing key feedback and review. The name GRASS was adopted by the PSC in a motion initiated by Vaclav Petras.

=== Governance ===
Submitted application for GRASS GIS to join NumFocus.

=== Event Planning and Organizing ===

* Created draft of schedule, agenda, and budget.
* Identified participants eligible for travel support.
** While the meeting is open to anyone, the NSF-funded travel support is based on priorities set in the NSF POSE project for the Developer Summit.
** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]

*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

=== Documentation and Tutorials ===
We finalized and prepared for launch Quarto-based tutorial website editable through GitHub. OSGeo provided a new domain [https://grass-tutorials.osgeo.org/ grass-tutorials.osgeo.org]. Initial set of tutorials were created by Veronica Andreo when she was part of the NSF POSE team (some tutorials will be finalized and released later). Anna Petrasova did the reviews, curation, posts for external tutorials, and transition from list of tutorials at the main website.

We did a major push to create Markdown files in the source code and enable the compilation of documentation for mkdocs. We also configured the mkdocs and revised the Markdown syntax in the files.

=== Communication and outreach ===

Renewed [https://www.youtube.com/@grass-gis Youtube channel @grass-gis] by adding playlists, organizing videos, and updating branding.

=== Brand ===

New branding concept (new logo, rename from "GRASS GIS" to "GRASS") presented to PSC; design led by Sarah White, website and documentation frontend by Corey White, coordination by Vaclav Petras.

=== Governance ===
Submitted application for GRASS GIS to join NumFocus.

=== Event Planning and Organizing ===

* Created draft of schedule, agenda, and budget.
* Identified participants eligible for travel support.
** While the meeting is open to anyone, the NSF-funded travel support is based on priorities set in the NSF POSE project for the Developer Summit.
** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

=== CMake transition ===
Ongoing work on [https://github.com/OSGeo/grass/pull/3621 CMake compilation] was partially covered by POSE.

=== Code Quality and Security ===

Code quality improvements in Python code:
* [https://github.com/OSGeo/grass/pull/3541 PR addressing Flake8 E501] (long lines in 158 files not fixable by automated tools)
* [https://github.com/OSGeo/grass/pull/3535 PR addressing Flake8 E401] (unused imports)

Vaclav Petras mentored a team of four students who create code security improvements in their NCSU class ''CSC 472: Cybersecurity Practicum''. The team created 12 PRs which were successfully merged, 7 additional experimental PRs (not merged) and 2 PRs which are still open at this time. Specifically, the team achieved the following:

* With the involvement and help from the other contributors, the team introduced Bandit and Coverity Scan as additional code scanning tools for Python and C, respectively.
* The team analyzed issues reported CodeQL, Bandit, and Coverity Scan and reported on relevance of different issues to the project (report privately shared with the GRASS Development Team).
* Vulnerability Triage Guide (also privately shared with the GRASS Development Team).
* The team also developed a [https://github.com/OSGeo/grass/security/policy security policy] for the project.
* The vulnerability reporting and security advisories were enabled based on the team recommendations.
* The team fixed several specific security issues in the code:
** [https://github.com/OSGeo/grass/pull/3469 packaging: Use subprocess instead of os.popen for change log creation #3469] (merged)

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

=== Documentation and Tutorials ===
We finalized and prepared for launch Quarto-based tutorial website editable through GitHub. OSGeo provided a new domain [https://grass-tutorials.osgeo.org/ grass-tutorials.osgeo.org]. Initial set of tutorials were created by Veronica Andreo when she was part of the NSF POSE team (some tutorials will be finalized and released later). Anna Petrasova did the reviews, curation, posts for external tutorials, and transition from list of tutorials at the main website.

We did a major push to create Markdown files in the source code and enable the compilation of documentation for mkdocs. We also configured the mkdocs and revised the Markdown syntax in the files.

=== Communication and outreach ===

Renewed [https://www.youtube.com/@grass-gis Youtube channel @grass-gis] by adding playlists, organizing videos, and updating branding.

=== Brand ===

New branding concept (new logo, rename from "GRASS GIS" to "GRASS") presented to PSC; design led by Sarah White, website and documentation frontend by Corey White, coordination by Vaclav Petras.

=== Governance ===
Submitted application for GRASS GIS to join NumFocus.

=== Event Planning and Organizing ===

* Created draft of schedule, agenda, and budget.
* Identified participants eligible for travel support.
** While the meeting is open to anyone, the NSF-funded travel support is based on priorities set in the NSF POSE project for the Developer Summit.
** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

* Created draft of schedule, agenda, and budget.
* Identified participants eligible for travel support.
** While the meeting is open to anyone, the NSF-funded travel support is based on priorities set in the NSF POSE project for the Developer Summit.
** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

Vaclav Petras mentored a team of four students who create code security improvements in their NCSU class ''CSC 472: Cybersecurity Practicum''. The team created 12 PRs which were successfully merged, 7 additional experimental PRs (not merged) and 2 PRs which are still open at this time. Specifically, the team achieved the following:

* With the involvement and help from the other contributors, the team introduced Bandit and Coverity Scan as additional code scanning tools for Python and C, respectively.
* The team analyzed issues reported CodeQL, Bandit, and Coverity Scan and reported on relevance of different issues to the project (report privately shared with the GRASS Development Team).
* Vulnerability Triage Guide (also privately shared with the GRASS Development Team).
* The team also developed a [https://github.com/OSGeo/grass/security/policy security policy] for the project.
* The vulnerability reporting and security advisories were enabled based on the team recommendations.

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

We finalized and prepared for launch Quarto-based tutorial website editable through GitHub. OSGeo provided a new domain [https://grass-tutorials.osgeo.org/ grass-tutorials.osgeo.org]. Initial set of tutorials were created by Veronica Andreo when she was part of the NSF POSE team (some tutorials will be finalized and released later). Anna Petrasova did the reviews, curation, posts for external tutorials, and transition from list of tutorials at the main website.

We did a major push to create Markdown files in the source code and enable the compilation of documentation for mkdocs. We also configured the mkdocs and revised the Markdown syntax in the files.

=== Communication and outreach ===

Renewed [https://www.youtube.com/@grass-gis Youtube channel @grass-gis] by adding playlists, organizing videos, and updating branding.

=== Event Planning and Organizing ===

* Created draft of schedule, agenda, and budget.
* Identified participants eligible for travel support.
** While the meeting is open to anyone, the NSF-funded travel support is based on priorities set in the NSF POSE project for the Developer Summit.
** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

* Created draft of schedule, agenda, and budget.
* Identified participants eligible for travel support.
** While the meeting is open to anyone, the NSF-funded travel support is based on priorities set in the NSF POSE project for the Developer Summit.
** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

We finalized and prepared for launch Quarto-based tutorial website editable through GitHub. OSGeo provided a new domain [https://grass-tutorials.osgeo.org/ grass-tutorials.osgeo.org]. Initial set of tutorials were created by Veronica Andreo when she was part of the NSF POSE team (some tutorials will be finalized and released later). Anna Petrasova did the reviews, curation, posts for external tutorials, and transition from list of tutorials at the main website.

We did a major push to create Markdown files in the source code and enable the compilation of documentation for mkdocs. We also configured the mkdocs and revised the Markdown syntax in the files.

=== Communication and outreach ===

Renewed [https://www.youtube.com/@grass-gis Youtube channel @grass-gis] by adding playlists, organizing videos, and updating branding.

=== Governance ===
Submitted application for GRASS GIS to join NumFocus.

=== Event Planning and Organizing ===

* Created draft of schedule, agenda, and budget.
* Identified participants eligible for travel support.
** While the meeting is open to anyone, the NSF-funded travel support is based on priorities set in the NSF POSE project for the Developer Summit.
** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

* Created draft of schedule, agenda, and budget.
* Identified participants eligible for travel support.
** While the meeting is open to anyone, the NSF-funded travel support is based on priorities set in the NSF POSE project for the Developer Summit.
** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

We finalized and prepared for launch Quarto-based tutorial website editable through GitHub. OSGeo provided a new domain [https://grass-tutorials.osgeo.org/ grass-tutorials.osgeo.org]. Initial set of tutorials were created by Veronica Andreo when she was part of the NSF POSE team (some tutorials will be finalized and released later). Anna Petrasova did the reviews, curation, posts for external tutorials, and transition from list of tutorials at the main website.

We did a major push to create Markdown files in the source code and enable the compilation of documentation for mkdocs. We also configured the mkdocs and revised the Markdown syntax in the files.

=== Communication and outreach ===

Renewed [https://www.youtube.com/@grass-gis Youtube channel @grass-gis] by adding playlists, organizing videos, and updating branding.

=== Governance ===

=== Event Planning and Organizing ===

* Created draft of schedule, agenda, and budget.
* Identified participants eligible for travel support.
** While the meeting is open to anyone, the NSF-funded travel support is based on priorities set in the NSF POSE project for the Developer Summit.
** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

=== Event Planning and Organizing ===

* Created draft of schedule, agenda, and budget.
* Identified participants eligible for travel support.
** While the meeting is open to anyone, the NSF-funded travel support is based on priorities set in the NSF POSE project for the Developer Summit.
** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

* [https://github.com/OSGeo/grass/pull/3535 PR addressing Flake8 E401] (unused imports)

Vaclav Petras mentored a team of four students who create code security improvements in their NCSU class ''CSC 472: Cybersecurity Practicum''. The team created 12 PRs which were successfully merged, 7 additional experimental PRs (not merged) and 2 PRs which are still open at this time. Specifically, the team achieved the following:

* With the involvement and help from the other contributors, the team introduced Bandit and Coverity Scan as additional code scanning tools for Python and C, respectively.
* The team analyzed issues reported CodeQL, Bandit, and Coverity Scan and reported on relevance of different issues to the project (report privately shared with the GRASS Development Team).
* Vulnerability Triage Guide (also privately shared with the GRASS Development Team).
* The team also developed a [https://github.com/OSGeo/grass/security/policy security policy] for the project.
* The vulnerability reporting and security advisories were enabled based on the team recommendations.
* The team fixed several specific security issues in the code:
** [https://github.com/OSGeo/grass/pull/3469 packaging: Use subprocess instead of os.popen for change log creation #3469] (merged)

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

=== Documentation and Tutorials ===
We finalized and prepared for launch Quarto-based tutorial website editable through GitHub. OSGeo provided a new domain [https://grass-tutorials.osgeo.org/ grass-tutorials.osgeo.org]. Initial set of tutorials were created by Veronica Andreo when she was part of the NSF POSE team (some tutorials will be finalized and released later). Anna Petrasova did the reviews, curation, posts for external tutorials, and transition from list of tutorials at the main website.

We did a major push to create Markdown files in the source code and enable the compilation of documentation for mkdocs. We also configured the mkdocs and revised the Markdown syntax in the files.

=== Communication and outreach ===

Renewed [https://www.youtube.com/@grass-gis Youtube channel @grass-gis] by adding playlists, organizing videos, and updating branding.

=== Governance ===
Submitted application for GRASS GIS to join NumFocus.

=== Event Planning and Organizing ===

* Created draft of schedule, agenda, and budget.
* Identified participants eligible for travel support.
** While the meeting is open to anyone, the NSF-funded travel support is based on priorities set in the NSF POSE project for the Developer Summit.
** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

We finalized and prepared for launch Quarto-based tutorial website editable through GitHub. OSGeo provided a new domain [https://grass-tutorials.osgeo.org/ grass-tutorials.osgeo.org]. Initial set of tutorials were created by Veronica Andreo when she was part of the NSF POSE team (some tutorials will be finalized and released later). Anna Petrasova did the reviews, curation, posts for external tutorials, and transition from list of tutorials at the main website.

We did a major push to create Markdown files in the source code and enable the compilation of documentation for mkdocs. We also configured the mkdocs and revised the Markdown syntax in the files.

=== Communication and outreach ===

Renewed [https://www.youtube.com/@grass-gis Youtube channel @grass-gis] by adding playlists, organizing videos, and updating branding.

=== Governance ===
Submitted application for GRASS GIS to join NumFocus.

=== Event Planning and Organizing ===

* Created draft of schedule, agenda, and budget.
* Identified participants eligible for travel support.
** While the meeting is open to anyone, the NSF-funded travel support is based on priorities set in the NSF POSE project for the Developer Summit.
** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

=== Documentation and Tutorials ===
We finalized and prepared for launch Quarto-based tutorial website editable through GitHub. OSGeo provided a new domain [https://grass-tutorials.osgeo.org/ grass-tutorials.osgeo.org]. Initial set of tutorials were created by Veronica Andreo when she was part of the NSF POSE team (some tutorials will be finalized and released later). Anna Petrasova did the reviews, curation, posts for external tutorials, and transition from list of tutorials at the main website.

We did a major push to create Markdown files in the source code and enable the compilation of documentation for mkdocs. We also configured the mkdocs and revised the Markdown syntax in the files.

=== Communication and outreach ===

Renewed [https://www.youtube.com/@grass-gis Youtube channel @grass-gis] by adding playlists, organizing videos, and updating branding.

=== Governance ===
Submitted application for GRASS GIS to join NumFocus.

=== Event Planning and Organizing ===

* Created draft of schedule, agenda, and budget.
* Identified participants eligible for travel support.
** While the meeting is open to anyone, the NSF-funded travel support is based on priorities set in the NSF POSE project for the Developer Summit.
** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

=== Documentation and Tutorials ===
We finalized and prepared for launch Quarto-based tutorial website editable through GitHub. OSGeo provided a new domain [https://grass-tutorials.osgeo.org/ grass-tutorials.osgeo.org]. Initial set of tutorials were created by Veronica Andreo when she was part of the NSF POSE team (some tutorials will be finalized and released later). Anna Petrasova did the reviews, curation, posts for external tutorials, and transition from list of tutorials at the main website.

We did a major push to create Markdown files in the source code and enable the compilation of documentation for mkdocs. We also configured the mkdocs and revised the Markdown syntax in the files.

=== Communication and outreach ===

Renewed [https://www.youtube.com/@grass-gis Youtube channel @grass-gis] by adding playlists, organizing videos, and updating branding.

=== Governance ===
Submitted application for GRASS GIS to join NumFocus.

=== Event Planning and Organizing ===

* Created draft of schedule, agenda, and budget.
* Identified participants eligible for travel support.
** While the meeting is open to anyone, the NSF-funded travel support is based on priorities set in the NSF POSE project for the Developer Summit.
** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

We finalized and prepared for launch Quarto-based tutorial website editable through GitHub. OSGeo provided a new domain [https://grass-tutorials.osgeo.org/ grass-tutorials.osgeo.org]. Initial set of tutorials were created by Veronica Andreo when she was part of the NSF POSE team (some tutorials will be finalized and released later). Anna Petrasova did the reviews, curation, posts for external tutorials, and transition from list of tutorials at the main website.

We did a major push to create Markdown files in the source code and enable the compilation of documentation for mkdocs. We also configured the mkdocs and revised the Markdown syntax in the files.

=== Communication and outreach ===

Renewed [https://www.youtube.com/@grass-gis Youtube channel @grass-gis] by adding playlists, organizing videos, and updating branding.

=== Governance ===
Submitted application for GRASS GIS to join NumFocus.

=== Event Planning and Organizing ===

* Created draft of schedule, agenda, and budget.
* Identified participants eligible for travel support.
** While the meeting is open to anyone, the NSF-funded travel support is based on priorities set in the NSF POSE project for the Developer Summit.
** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

Several reviewers, not supported by the NSF POSE project, played crucial role not only in reviewing, but also in determining the right fixes. The NSF POSE project personnel focused on fixing issues reported by Flake8, Coverity Scan, and Cppcheck, however also Ruff and Pylint are utilized in GRASS GIS thanks to other contributors.

A configure file for Cppcheck is now included in the repository highlighting the level of compliance and aiding contributors in local analysis and subsequent implementation of fixes ([https://github.com/OSGeo/grass/pull/4766 PR #4766]).

Finally, we created a new public GitHub project in the OSGeo GitHub organization for [https://github.com/orgs/OSGeo/projects/11 GRASS GIS Security] to track and communicate progress on the security front with 147 resolved items and 8 in-progress items at the time of writing.

=== Documentation, both Internal and External ===

* To improve indexing of GRASS GIS manual pages, we revised our current sitemap ([https://github.com/OSGeo/grass-website/pull/482 grass-website/pull/482)]), added a updated sitemap to Google Search Console and Bing, fixed robots.txt, and triggered and re-triggered the indexing many times to make Google consume the new content. While before, some searches gave outdated documentation, experimental websites, or unofficial resources only, now the official website and stable documentation is returned as the first search result.
* All older manuals, including version 6.4 and 6.5, are now available (restored) so that search engines can consume them and old links and indices continue to work. They now newly contain the canonical URLs so that search engines understand the structure and don't penalize duplicate content.
* On OSGeo server which hosts GRASS GIS website, we replaced some of the redirects in Apache by local soft links so that URL like grass.osgeo.org/grass-stable stay as is for both humans and machines and don't redirect to specific version (easier to copy-paste from a browser URL bar and easier for search engine to understand what is the page to show).
* We implemented the necessary changes into the cronjobs and did overall updates to enable build of the server-side documentation jobs locally for testing purposes. The most relevant PRs are:
** [https://github.com/OSGeo/grass-addons/pull/1241 Inject canonical URLs into older manual pages (SEO) #1241]
** [https://github.com/OSGeo/grass-addons/pull/1173 Fix red new version box injection and script documentation #1173]
** [https://github.com/OSGeo/grass-addons/pull/1215 Expand script to run stand-alone #1215]
* We advanced the [https://github.com/orgs/OSGeo/projects/9 GRASS Markdown Documentation project].
* New and better wording for intro to imagery tools: [https://github.com/OSGeo/grass/pull/4536 Add intro text to imageryintro.html #4536]
* List of GRASS GIS profiles on different websites is now in an internal PSC document.
* Documentation of all the internal infrastructure, especially that of grass.osgeo.org server, is now in an internal PSC document.
* We painstakingly identified and described all maintenance procedures performed by Markus Neteler in OSGeo SAC capacity for GRASS GIS and as a contributor to GRASS GIS for better work distribution.
* Most of the work on the documentation was done through a contract with Markus Neteler with additional help from Martin Landa for the transition to Markdown.

=== Documentation and Tutorials ===
We finalized and prepared for launch Quarto-based tutorial website editable through GitHub. OSGeo provided a new domain [https://grass-tutorials.osgeo.org/ grass-tutorials.osgeo.org]. Initial set of tutorials were created by Veronica Andreo when she was part of the NSF POSE team (some tutorials will be finalized and released later). Anna Petrasova did the reviews, curation, posts for external tutorials, and transition from list of tutorials at the main website.

We did a major push to create Markdown files in the source code and enable the compilation of documentation for mkdocs. We also configured the mkdocs and revised the Markdown syntax in the files.

=== Communication and outreach ===

Renewed [https://www.youtube.com/@grass-gis Youtube channel @grass-gis] by adding playlists, organizing videos, and updating branding.

=== Governance ===
Submitted application for GRASS GIS to join NumFocus.

=== Event Planning and Organizing ===

* Created draft of schedule, agenda, and budget.
* Identified participants eligible for travel support.
** While the meeting is open to anyone, the NSF-funded travel support is based on priorities set in the NSF POSE project for the Developer Summit.
** Specifically, we are inviting individuals identified based on the following criteria (in this order; moving to the next group if there is still available places):
*** Top 20 contributors to OSGeo/grass in the last two years (2023-2024), but not a bot or NSF POSE personnel (contributing only within NSF POSE). (After exclusions, this is less than 10 people.)
*** PSC member before or after 2024 elections, but not NSF POSE personnel at the time of the meeting. (With PSC members currently contributing code as well, this is only a couple of people after exclusions.)
*** Active participant in one of the mentoring programs. (Participant demonstrated the activity by attending meetings, reporting progress, or submitting code for feedback or review.)
*** Contributors to connections and interfaces prioritized in or during the NSF POSE project:
**** R packages (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
**** GRASS GIS code in QGIS (2 slots for active contributors or maintainers determined by previously established contacts in the given community through their activity on a relevant code base.)
*** Contributors in "write" teams for OSGeo/grass, OSGeo/grass-addons, OSGeo/grass-website, and OSGeo/grass-tutorials repositories. (Almost all fall into one of the above groups.)
*** Contributors to closely related projects, specifically actinia, the GRASS GDAL driver, and the GRASS GeoServer datastore.
* Sent individual invites to participants eligible for travel support. (ongoing)

GRASS GSoC Ideas 2026

2026-01-25T04:12:06Z

Wenzeslaus: Fix known code defects

== About ==
Important: While we are still an OSGeo project, we changed our fiscal sponsor to [https://numfocus.org/ NumFOCUS].

''As a result, GRASS participates in GSoC under the [https://numfocus.org/ NumFOCUS] umbrella organization.''

Read more about our governance [https://grass.osgeo.org/about/governance/ on GRASS website].

* [https://numfocus.org/programs/google-summer-code The NumFOCUS GSoC main page]
* [https://github.com/numfocus/gsoc/blob/master/CONTRIBUTING-contributors.md NumFOCUS guidelines for contributors].
* [https://summerofcode.withgoogle.com/ Official GSoC page at Google]

== AI Tool Usage Policy ==
We acknowledge that applicants may use AI tools (like ChatGPT, Copilot, etc.) to assist with proposal writing and coding. However:

* Your proposal should reflect your own understanding and voice. AI-generated "slop" (overly generic or regurgitated content) is easy to spot and will hurt your application.
* We evaluate applications primarily on GitHub contributions and communication with the GRASS community, not just proposal polish.
* Show us you understand the project through high-quality pull requests on GitHub.
* Disclose AI usage: If you use AI tools in your proposal or code contributions, please disclose the extent to which you used them (e.g., for brainstorming, proofreading, code suggestions, etc.).

== Ideas ==
If you are a student you can suggest a new idea or pick up an existing one. In any case write about it to [https://discourse.osgeo.org/c/grass/developer/61 OSGeo Discourse forum for GRASS developers], [https://github.com/OSGeo/grass/discussions GitHub Discussions], or [https://gitter.im/grassgis/community Gitter].

You are invited as well to have a close look at ideas from previous years ([https://trac.osgeo.org/grass/wiki/GSoC/2014 2014], [https://trac.osgeo.org/grass/wiki/GSoC/2015 2015], [https://trac.osgeo.org/grass/wiki/GSoC/2016 2016],

[https://trac.osgeo.org/grass/wiki/GSoC/2023 2023])
which have not yet been implemented.
You can also look at accepted GRASS GSoC [https://trac.osgeo.org/grass/wiki/GSoC projects from previous years] for an idea of scope.''

=== Parallelization of existing tools ===

There are several tools that would benefit from parallelization with OpenMP, e.g. r.texture, r.horizon, r.fill.stats, r/v.surf.idw, r.viewshed, v.to.rast, r.grow.distance, v.surf.bspline, ...
For overview of current state, see [[Raster_Parallelization_with_OpenMP]].

* Requirements: familiarity with C, OpenMP
* Mentor: Huidae Cho
* Co-mentor: Vaclav Petras, Anna Petrasova
* Project length: 175 or 350 hours (take your pick)
* Rating: medium
* Expected Outcomes: parallelized module or modules, depending on complexity

=== Improve GRASS user experience in Jupyter Notebook ===
[[File:Jupyter_interactive_viewshed.png|500px|thumb|right|InteractiveMap in grass.jupyter library]]
Python package [https://grass.osgeo.org/grass-stable/manuals/libpython/grass.jupyter.html grass.jupyter] was developed during [https://trac.osgeo.org/grass/wiki/GSoC/2021/JupyterAndGRASS GSoC 2021] to simplify running GRASS from Jupyter Notebooks and displaying data. This project could focus on adding features such as increasing interactivity of displayed data using ipyleaflet, adding API for managing projects and subprojects (i.e., locations/mapsets), creating GUI for commands, ...

* Requirements: Python
* Mentor: Anna Petrasova
* Co-mentor: Vaclav Petras, Helena Mitasova, Corey White
* Project length: 175 or 350 hours (take your pick)
* Rating: easy to medium
* Expected Outcomes: improved user experience when using GRASS through notebooks
* Test of skills: https://github.com/OSGeo/grass/issues/3276, or write a test for [https://github.com/OSGeo/grass/tree/main/python/grass/jupyter grass.jupyter library] using python unittest or pytest, more info [https://grass.osgeo.org/grass-devel/manuals/libpython/gunittest_testing.html here].

=== Add JSON output to different tools in C ===
There are several tools in GRASS that would benefit from a JSON-formatted output, see [https://github.com/OSGeo/grass/issues/3020 this issue for a list of tools]. Besides adding the JSON output, the work would also include adding tests and basic documentation.
* Requirements: C, Python for tests
* Mentor: Vaclav Petras
* Co-mentor: Anna Petrasova, Corey White
* Project length: 175 or 350 hours (take your pick)
* Rating: easy to medium
* Expected Outcomes: one or more (depending on project length and complexity of the tool) tools with well tested JSON output
* Test of skills: Address https://github.com/OSGeo/grass/issues/1044 for r.surf.fractal

=== Support writing tests with pytest ===

* The current testing framework, ''[https://grass.osgeo.org/grass-stable/manuals/libpython/gunittest.html grass.gunittest]'', was written before migration to Git/GitHub and when long free runs in 3rd party services were unthinkable. Additionally, some no longer relevant goals were prioritized, such as independence on the current code, detailed custom HTML reports, success tracking over time, and high specialization towards GRASS-specifics.
* ''grass.gunittest'' is based on Python ''unittest'' package and many projects since then migrated to //pytest//, e.g., GDAL and Numpy. While ''unittest'' is inspired by Java's JUnit, ''pytest'' is designed to support writing small, readable tests, and uses plain `assert` statements instead of many different assert methods.
* Using ''pytest'' should lead to tests which feel more like Python scripts and to minimum of testing-specific code.
* An example issue of ''grass.gunittest'' is that it doesn't work well with tests of the main GRASS executable (prominence of `grass ... --exec` is yet another new thing which changed since ''grass.gunittest'' was designed).
* Two main things needed:
** Create general comparison functions from the ''grass.gunittest'' assert methods so that they can be used with pytest.
** Current grass.script.setup.init function and grass.script.core.create_location function don't work well in the context of a pytest test function. More
* Additional things needed:
** Fixture for pytest to set up and tear down a GRASS session in a temporary mapset.

* Requirements: Python
* Project length: 175 or 350 hours (take your pick)
* Mentor: Vaclav Petras
* Co-mentor: Stefan Blumentrath
* Proposed by: Vaclav Petras
* Rating: easy to medium
* Expected Outcomes: Convenient way of writing tests with pytest
* Test of skills: Fix failing tests and/or write new tests (more is better). Alternatively, addressing a smaller problem in the testing framework is a good task, too.

=== Fix known code defects ===

* Fix code defects (security or code quality) such as those reported by Coverity Scan.
* Mentors: Vaclav Petras
* Co-mentors: ?
* Proposed by: Vaclav Petras
* Project length: 175 or 350 hours (flexible)
* Rating: medium
* Requirements:
** Language: C
** Proposal: Define milestones which will be used during the evaluation.
* Expected outcomes:
** Reduction of issues by 70-100%.
** New tests for changed code if missing.
* Test and training tasks (complete more than one): Fix cppcheck issue.

=== Subcommand CLI for GRASS ===

* Make running of GRASS tools in command line as easy as possible.
** `grass run r.slope.aspect elevation=elevation.tiff slope=slope.tiff aspect=aspect.tiff`
* Project length: 350 hours
* Rating: medium
* Requirements:
** Language: Python
** Proposal: Student needs to show sufficient understanding of data and project handling in GRASS. Furthermore, the proposal needs to present, at least, concrete formulation of ideas, identification of missing and existing parts, and new subcommands.
* Mentors: Vaclav Petras
* Co-mentors: Stefan Blumentrath, Corey White
* Proposed by: Vaclav Petras
* Expected outcomes:
** A subcommand which runs a GRASS tool on GeoTiff and GeoPackage in one step.
** A complete parity with the existing CLI.
** An underlying Python API which will be used to implement the CLI.
* Test and training tasks (complete one or more): Add a subcommand, sub-subcommand, or an option to the experimental interface (with tests).
** Add `--region` to set a temporary computational region for the execution, e.g. `--region="raster=raster_name"`.
** Add `--import-raster=some/file.tiff` which imports (r.import) a raster file (same for vector and similarly for export).
** Add `--link-raster=some/file.tiff` which links (r.external) a raster file (same for vector and similarly for r.external.out).

Current state:

# Reveals the existing subcommands
PYTHONPATH=$(grass --config python-path) python -m grass.app --help
# Allows running subset of commands
grass run --help



=== GUI: Add space-time datasets support in Data Catalog ===
[[File:GUI_data_tab.png|400px|thumb|right|Data catalog]]
Currently GRASS Data Catalog shows only raster and vector maps. The goal of this project is to add support for space-time datasets. It is mainly space-time raster datasets. In the next phase of the project support for other types of space-time datasets (vector and 3D raster) could be added. Besides displaying space-time datasets in the layer tree, it is also about adding the equivalent functionality currently available for raster and vector layers from the context menu.

* Requirements: familiar with Python
* Project length: 175 or 350 hours
* Mentor: Martin Landa
* Co-mentor: Anna Petrasova
* Proposed by: Martin Landa
* Rating: medium
* Expected Outcomes: 175 hours basic support for space-time raster datasets; 350 extended support also for other space-time datasets types (vector, 3D raster)
* Test of skills:
** suggest/implement solution for completing https://github.com/OSGeo/grass/issues/2599

=== Add {your research idea} to GRASS ===

* In general, you can propose any topic, but you can specifically propose integrating your research or research idea into GRASS.
* Requirements:
** Language:
*** Depends on the project, often Python, sometimes C.
*** Adding your latest ecological analysis
** Proposal:
*** Discuss relevance to GRASS.
*** Describe technical steps needed for integration.
*** Describe whether it is an addition of a tool (module) or a change in one of the libraries. If it is a tool, specify if it should be included in the core grass repository or in grass-addons repository and why.
*** Specify what research was done and what needs to be accomplished in order to have usable product at the end of summer.
*** Specify who will provide the research expertise.
* Project length: 175 or 350 hours (take your pick)
* Rating: from low to hard
* Mentors:
** GRASS project will provide technical mentors, but it is up to the applicant to ensure the research part is mentored well. An exception may be granted to applicants which can demonstrate that the research is finished or that they have enough expertise themselves.
** Possible technical mentors: Vaclav Petras, Anna Petrasova
** Research mentors: Bring in an expert from your field, e.g., your academic advisor or project principal investigator (if needed).
* Proposed by: Vaclav Petras
* Expected outcome: Working feature which is integrated and merged at the end of the project.
* Test and training tasks:
** Create a test in Python for an existing tool in the grass-addons repository or in the core grass repository.

== Tips for students ==
* Follow official [https://github.com/numfocus/gsoc/blob/master/CONTRIBUTING-contributors.md NumFOCUS guidelines].
* Include "GRASS" in the title of our idea to easily distinguish ideas and projects inside NumFOCUS.
* If you have your own ideas we encourage you to propose them. Explain them on the [https://discourse.osgeo.org/c/grass/developer/61 on our Discourse].
* Follow some good practices in your ideas and proposals:
** Stress why the project would be useful.
** Show that you know how you will proceed. That is, make sure that you can demonstrate that the proposal is feasible in the given time frame.
** Be specific in the implementation (or at least as specific as you can).
** Explain what the final product will look like and how it will work. You can add drawings or mock-ups.
** Explain how the idea relates to existing GRASS functions, features, and needs.
** Do not include steps such as "install GRASS", "compile GRASS libraries (on my machine)", "read about the API". You should do this before applying to GSoC.
* Compile GRASS from source and prepare environment for development:
** Read [https://github.com/OSGeo/grass/blob/main/CONTRIBUTING.md CONTRIBUTING file].
* Prove your worth by being active on the [https://discourse.osgeo.org/c/grass/developer/61 GRASS Discourse] or other channels ([https://github.com/OSGeo/grass/discussions GitHub Discussions], fix some [https://github.com/OSGeo/grass/issues bugs], and/or implement some (smaller) features, or write some (simpler) GRASS module, and post it to mailing list. There's no better way to demonstrate your willingness and abilities. Do this before start you apply to GSoC.
* Also note that fixing existing bugs and/or implementing enhancements will be a part of student evaluation.

=== Support writing tests with pytest ===

* The current testing framework, ''[https://grass.osgeo.org/grass-stable/manuals/libpython/gunittest.html grass.gunittest]'', was written before migration to Git/GitHub and when long free runs in 3rd party services were unthinkable. Additionally, some no longer relevant goals were prioritized, such as independence on the current code, detailed custom HTML reports, success tracking over time, and high specialization towards GRASS-specifics.
* ''grass.gunittest'' is based on Python ''unittest'' package and many projects since then migrated to //pytest//, e.g., GDAL and Numpy. While ''unittest'' is inspired by Java's JUnit, ''pytest'' is designed to support writing small, readable tests, and uses plain `assert` statements instead of many different assert methods.
* Using ''pytest'' should lead to tests which feel more like Python scripts and to minimum of testing-specific code.
* An example issue of ''grass.gunittest'' is that it doesn't work well with tests of the main GRASS executable (prominence of `grass ... --exec` is yet another new thing which changed since ''grass.gunittest'' was designed).
* Two main things needed:
** Create general comparison functions from the ''grass.gunittest'' assert methods so that they can be used with pytest.
** Current grass.script.setup.init function and grass.script.core.create_location function don't work well in the context of a pytest test function. More
* Additional things needed:
** Fixture for pytest to set up and tear down a GRASS session in a temporary mapset.

* Requirements: Python
* Project length: 175 or 350 hours (take your pick)
* Mentor: Vaclav Petras
* Co-mentor: Stefan Blumentrath
* Proposed by: Vaclav Petras
* Rating: easy to medium
* Expected Outcomes: Convenient way of writing tests with pytest
* Test of skills: Fix failing tests and/or write new tests (more is better). Alternatively, addressing a smaller problem in the testing framework is a good task, too.

=== Subcommand CLI for GRASS ===

* Make running of GRASS tools in command line as easy as it is to run GDAL commands.

# Reveals the existing subcommands
PYTHONPATH=$(grass --config python-path) python -m grass.app --help
# Allows running subset of commands
grass run --help

** `grass run r.slope.aspect elevation=elevation.tiff slope=slope.tiff aspect=aspect.tiff`
** CLI like GDAL has.
** No GRASS Database, Location, Mapset to deal with.
** No import, export from user perspective.
** Reasonable defaults for things like region.
** CLI and API still allows user to specify any of the above.
* Idea page with details: wiki:GSoC/2021/EasyToUseCliAndApiIdea
* Project length: 350 hours
* Rating: medium
* Requirements:
** Language: Python
** Proposal: Student needs to show sufficient understanding of data and project handling in GRASS. Furthermore, the proposal needs to present, at least, concrete formulation of ideas, identification of missing and existing parts, and new subcommands.
* Mentors: Vaclav Petras
* Co-mentors: Stefan Blumentrath, Corey White
* Proposed by: Vaclav Petras
* Expected outcomes:
** A subcommand which runs a GRASS tool on GeoTiff and GeoPackage in one step.
** A complete parity with the existing CLI.
** An underlying Python API which will be used to implement the CLI.
* Test and training tasks (complete one or more):
** Add a subcommand, sub-subcommand, or an option to the experimental interface.
** Add `--region` to set a temporary computational region for the execution, e.g. `--region="raster=raster_name"`.
** Add `--import-raster=some/file.tiff` which imports (r.import) a raster file (same for vector and similarly for export).
** Add `--link-raster=some/file.tiff` which links (r.external) a raster file (same for vector and similarly for r.external.out).



=== GUI: Add space-time datasets support in Data Catalog ===
[[File:GUI_data_tab.png|400px|thumb|right|Data catalog]]
Currently GRASS Data Catalog shows only raster and vector maps. The goal of this project is to add support for space-time datasets. It is mainly space-time raster datasets. In the next phase of the project support for other types of space-time datasets (vector and 3D raster) could be added. Besides displaying space-time datasets in the layer tree, it is also about adding the equivalent functionality currently available for raster and vector layers from the context menu.

* Requirements: familiar with Python
* Project length: 175 or 350 hours
* Mentor: Martin Landa
* Co-mentor: Anna Petrasova
* Proposed by: Martin Landa
* Rating: medium
* Expected Outcomes: 175 hours basic support for space-time raster datasets; 350 extended support also for other space-time datasets types (vector, 3D raster)
* Test of skills:
** suggest/implement solution for completing https://github.com/OSGeo/grass/issues/2599

=== Add {your research idea} to GRASS ===

* In general, you can propose any topic, but you can specifically propose integrating your research or research idea into GRASS.
* Requirements:
** Language:
*** Depends on the project, often Python, sometimes C.
*** Adding your latest ecological analysis
** Proposal:
*** Discuss relevance to GRASS.
*** Describe technical steps needed for integration.
*** Describe whether it is an addition of a tool (module) or a change in one of the libraries. If it is a tool, specify if it should be included in the core grass repository or in grass-addons repository and why.
*** Specify what research was done and what needs to be accomplished in order to have usable product at the end of summer.
*** Specify who will provide the research expertise.
* Project length: 175 or 350 hours (take your pick)
* Rating: from low to hard
* Mentors:
** GRASS project will provide technical mentors, but it is up to the applicant to ensure the research part is mentored well. An exception may be granted to applicants which can demonstrate that the research is finished or that they have enough expertise themselves.
** Possible technical mentors: Vaclav Petras, Anna Petrasova
** Research mentors: Bring in an expert from your field, e.g., your academic advisor or project principal investigator (if needed).
* Proposed by: Vaclav Petras
* Expected outcome: Working feature which is integrated and merged at the end of the project.
* Test and training tasks:
** Create a test in Python for an existing tool in the grass-addons repository or in the core grass repository.

GRASS GSoC Ideas 2026

2026-01-25T03:36:32Z

Wenzeslaus: GRASS GIS -> GRASS

== About ==
Important: While we are still an OSGeo project, we changed our fiscal sponsor to [https://numfocus.org/ NumFOCUS].

''As a result, GRASS participates in GSoC under the [https://numfocus.org/ NumFOCUS] umbrella organization.''

Read more about our governance [https://grass.osgeo.org/about/governance/ on GRASS website].

* [https://numfocus.org/programs/google-summer-code The NumFOCUS GSoC main page]
* [https://github.com/numfocus/gsoc/blob/master/CONTRIBUTING-contributors.md NumFOCUS guidelines for contributors].
* [https://summerofcode.withgoogle.com/ Official GSoC page at Google]

== AI Tool Usage Policy ==
We acknowledge that applicants may use AI tools (like ChatGPT, Copilot, etc.) to assist with proposal writing and coding. However:

* Your proposal should reflect your own understanding and voice. AI-generated "slop" (overly generic or regurgitated content) is easy to spot and will hurt your application.
* We evaluate applications primarily on GitHub contributions and communication with the GRASS community, not just proposal polish.
* Show us you understand the project through high-quality pull requests on GitHub.
* Disclose AI usage: If you use AI tools in your proposal or code contributions, please disclose the extent to which you used them (e.g., for brainstorming, proofreading, code suggestions, etc.).

== Ideas ==
If you are a student you can suggest a new idea or pick up an existing one. In any case write about it to [https://discourse.osgeo.org/c/grass/developer/61 OSGeo Discourse forum for GRASS developers], [https://github.com/OSGeo/grass/discussions GitHub Discussions], or [https://gitter.im/grassgis/community Gitter].

You are invited as well to have a close look at ideas from previous years ([https://trac.osgeo.org/grass/wiki/GSoC/2014 2014], [https://trac.osgeo.org/grass/wiki/GSoC/2015 2015], [https://trac.osgeo.org/grass/wiki/GSoC/2016 2016],
[https://trac.osgeo.org/grass/wiki/GSoC/2017 2017],
[https://trac.osgeo.org/grass/wiki/GSoC/2018 2018],
[https://trac.osgeo.org/grass/wiki/GSoC/2019 2019],
[https://trac.osgeo.org/grass/wiki/GSoC/2020 2020],

which have not yet been implemented.
You can also look at accepted GRASS GSoC [https://trac.osgeo.org/grass/wiki/GSoC projects from previous years] for an idea of scope.''

=== Parallelization of existing tools ===

There are several tools that would benefit from parallelization with OpenMP, e.g. r.texture, r.horizon, r.fill.stats, r/v.surf.idw, r.viewshed, v.to.rast, r.grow.distance, v.surf.bspline, ...
For overview of current state, see [[Raster_Parallelization_with_OpenMP]].

PSC Meeting 2025-11-14

2025-12-31T18:06:06Z

Wenzeslaus: /* Minutes */

== Participants ==

* Anna Petrasova
* Huidae Cho
* Linda Karlovska
* Markus Neteler
* Nicklas Larsson
* Paulo van Breugel
* Vaclav Petras
* Veronica Andreo

== Agenda ==

The topics proposed are:

* Report from NumFOCUS Project Summit (VP)
* GRASS Wiki under DDOS attack, see https://discourse.osgeo.org/t/grass-wiki-under-ddos-attack/150717
* New wiki page: [[Organizing GRASS Contributor Events]]
* GRASS Meeting 2026 - Luca's proposal
* Upcoming releases:
** Release 8.4.2 (due to relevant [https://github.com/OSGeo/grass/compare/8.4.1...releasebranch_8_4 fixes]; the branch-CI is also functional again) - [https://github.com/OSGeo/grass/milestone/27 milestone]
** Release 8.5.0 - [https://github.com/OSGeo/grass/milestone/22 milestone]
* Reimburse Alen for stickers he bought to take to NZ

== Minutes ==

* Report from NumFOCUS Project Summit:
** VP participated of the NumFOCUS projects summit; there were not many other projects attending.
** There are calls for small grants (USD 10K per project per year), that we should apply for, and ideally use them for development.
** It seems we need to apply as a project, but it is not clear who submits. In any case, the person interested in the money should lead the effort. See: https://numfocus.org/programs/small-development-grants.
** We had a meeting with them on Tue 18th, but AP will ask them to move it because neither VP nor VA can attend. New date: Dec 10th, 2025.

* GRASS wiki under attack by botnet:
** MN set up countermeasures on the server, instructions to be dumped in our infrastructure shared doc
** Not everyone has access to that doc, so we shall review and discuss our shared folder and files access “policy”.

* New wiki page on organizing GRASS events:
** https://grasswiki.osgeo.org/wiki/Organizing_GRASS_Contributor_Events

* GRASS meeting San Michele 2026:
** See [https://lists.osgeo.org/pipermail/grass-psc/2025-September/003054.html Luca's proposal].
** Nicklas is not available for any of the proposed dates.
** For AP and VP any of the dates are fine.
** Paulo: 50% with the second date.
** HC: probably the second date.
** MN and VA: any date fine for now.

* Release 8.4.2:
** VP and MN will agree on a date soon to do the release together.
** Edouard will be invited, too.

* Release 8.5:
** It will have CMake in the source code as experimental feature to try for users who compile code themselves (but extensions won’t work for them).
** FHS won’t work with CMake yet.
** It’s a matter of communication about what’s there in the source code. Binaries will be with autotools, so addons will work.
** Blockers: there’s an issue with r.blend and something with r.patch with vrt and nprocs > 1 (the latter found by Metz, but still unreported)
** New python API, VP will call for a webinar on it by mid-dec, to show how it works and collect some feedback, too.
** JSON stuff and mkdocs is in good shape to go.
** Jupyter notebook PR needs to be reviewed, it does not work in windows, but this is not a blocker, we can mark it as experimental.
** Drop support for PROJ < 8 and GDAL < 3? Nicklas created issues to get feedback, it could be done before the release. See [https://github.com/OSGeo/grass/issues/6628 #6628] and [https://github.com/OSGeo/grass/issues/6629 #6629].

* Motion proposed and passed to reimburse Alen for the stickers. VP will contact Michael Smith, so Alen gets reimbursed.

* Plan extraordinary meeting - PSC + Luca to plan 2026 budget + community meeting when the call for OSGeo budget is out.
** VP proposal: include an item to promote GRASS in other than FOSS4G conferences.
