* Discussion with Corey White on trying to build docs with Zensical, and dropping Sphinx for [https://zensical.org/docs/setup/extensions/mkdocstrings/ mkdocstrings]
* Discussion with Vaclav Petras on Windows builds and Fable:
** The nsis installer had a change to do (as debugged last year by me in [https://github.com/OSGeo/grass/issues/5663 #5663]), but we don't know how to do it well. We suggested to let Anthropic's Fable try to do it before it stopped being included in the Claude subscription.
** For us to try out the fixed nsis installer script, Fable should be able to create the installer in CI. It is being tried in [https://github.com/echoix/grass/pull/664 echoix#664]/[https://github.com/wenzeslaus/grass/pull/12 wenzeslaus#12]
** Also suggested to use Fable to attempt to solve issues in a pending Sphinx PR that we were stuck for too long, (Stcuk PR: [https://github.com/OSGeo/grass/pull/7526 #7526], result: [https://github.com/wenzeslaus/grass/pull/11 wenzeslaus#11])
==== 2026-07-12 ====

* Reviewed PRs: [https://github.com/OSGeo/grass/pull/7663 #7663], [https://github.com/OSGeo/grass-website/pull/635 grass-website#635], [https://github.com/OSGeo/grass/pull/7337 #7337], [https://github.com/OSGeo/grass/pull/7672 #7672], [https://github.com/OSGeo/grass/pull/7684 #7684], [https://github.com/OSGeo/grass/pull/7687 #7687]
* Worked on the last sscanf CodeQL alert, for [https://github.com/OSGeo/grass/pull/7673 #7673]
* Tested out windows standalone installer built in CI [https://github.com/echoix/grass/pull/664 echoix#664]. Almost works, as it installs, but it doesn't start because of a path error. Wrote some notes about windows compilation in CI in relation to addons in Vashek's google doc.
* Wrote notes on the windows build script having two versions, where OSGeo4W uses a different one than the one we use in CI for our tests, and they diverged
* Submitted PR of AI findings for tests of g.md2man [https://github.com/OSGeo/grass/pull/7679 #7679]
* Configured CI required checks to not wait for successful checks during the code sprint, with the new rights given to me. Discussed with Vashek on what approach we'd want for the 4 ubuntu job configurations.
** Commented on an issue closed today [https://github.com/OSGeo/grass/issues/1313 #1313] about cppcheck: cppcheck could be useful to cover a bit more configuration combinations, but as discussed, only being to compile would only get us so far without testing.
* Discussion with Vashek on AI policy and approach to use with AI, low-quality contributors; Approach on renovate updates; Wishes on release cadence
* Multiple reviews and pair brainstorming on grass-website with Corey White, including [https://github.com/OSGeo/grass-website/pull/635 grass-website#635], [https://github.com/OSGeo/grass-website/pull/637 grass-website#637], [https://github.com/OSGeo/grass-website/pull/639 grass-website#639], [https://github.com/OSGeo/grass-website/pull/634 grass-website#634], [https://github.com/OSGeo/grass-website/pull/640 grass-website#640]

* Discussion with Corey White on trying to build docs with Zensical, and dropping Sphinx for [https://zensical.org/docs/setup/extensions/mkdocstrings/ mkdocstrings]
* Discussion with Vaclav Petras on Windows builds and Fable:
** The nsis installer had a change to do (as debugged last year by me in [https://github.com/OSGeo/grass/issues/5663 #5663]), but we don't know how to do it well. We suggested to let Anthropic's Fable try to do it before it stopped being included in the Claude subscription.
** For us to try out the fixed nsis installer script, Fable should be able to create the installer in CI. It is being tried in [https://github.com/echoix/grass/pull/664 echoix#664]/[https://github.com/wenzeslaus/grass/pull/12 wenzeslaus#12]
** Also suggested to use Fable to attempt to solve issues in a pending Sphinx PR that we were stuck for too long, (Stcuk PR: [https://github.com/OSGeo/grass/pull/7526 #7526], result: [https://github.com/wenzeslaus/grass/pull/11 wenzeslaus#11])
==== 2026-07-12 ====

* Reviewed PRs: [https://github.com/OSGeo/grass-addons/pull/641 grass-addons#641], [https://github.com/OSGeo/grass/pull/7635 #7635], [https://github.com/OSGeo/grass/pull/7671 #7671], [https://github.com/OSGeo/grass/pull/7669 #7669]
* Video call on FHS
* First review of Fable windows installer in CI on [https://github.com/echoix/grass/pull/664 echoix#664]

==== 2026-07-13 ====
* Reviewed PRs: [https://github.com/OSGeo/grass/pull/7663 #7663], [https://github.com/OSGeo/grass-website/pull/635 grass-website#635], [https://github.com/OSGeo/grass/pull/7337 #7337], [https://github.com/OSGeo/grass/pull/7672 #7672], [https://github.com/OSGeo/grass/pull/7684 #7684], [https://github.com/OSGeo/grass/pull/7687 #7687]
* Worked on the last sscanf CodeQL alert, for [https://github.com/OSGeo/grass/pull/7673 #7673]
* Tested out windows standalone installer built in CI [https://github.com/echoix/grass/pull/664 echoix#664]. Almost works, as it installs, but it doesn't start because of a path error. Wrote some notes about windows compilation in CI in relation to addons in Vashek's google doc.
* Wrote notes on the windows build script having two versions, where OSGeo4W uses a different one than the one we use in CI for our tests, and they diverged
* Submitted PR of AI findings for tests of g.md2man [https://github.com/OSGeo/grass/pull/7679 #7679]
* Configured CI required checks to not wait for successful checks during the code sprint, with the new rights given to me. Discussed with Vashek on what approach we'd want for the 4 ubuntu job configurations.
** Commented on an issue closed today [https://github.com/OSGeo/grass/issues/1313 #1313] about cppcheck: cppcheck could be useful to cover a bit more configuration combinations, but as discussed, only being to compile would only get us so far without testing.
* Discussion with Vashek on AI policy and approach to use with AI, low-quality contributors; Approach on renovate updates; Wishes on release cadence
* Multiple reviews and pair brainstorming on grass-website with Corey White, including [https://github.com/OSGeo/grass-website/pull/635 grass-website#635], [https://github.com/OSGeo/grass-website/pull/637 grass-website#637], [https://github.com/OSGeo/grass-website/pull/639 grass-website#639], [https://github.com/OSGeo/grass-website/pull/634 grass-website#634], [https://github.com/OSGeo/grass-website/pull/640 grass-website#640]
* Worked on CMake formatting, moving forward the PR a contributor opened for Gersemi, PR [https://github.com/OSGeo/grass/pull/7663 #7663], discussed weird finding with Vashek, lead to issue [https://github.com/OSGeo/grass/issues/7686 #7686]. To be continued the next day.
* Opened PR [https://github.com/OSGeo/grass/pull/7685 #7685] (merged), [https://github.com/OSGeo/grass/pull/7683 #7683] (needs more work/investigation), [https://github.com/OSGeo/grass/pull/7680 #7680] (merged)

* Discussion with Corey White on trying to build docs with Zensical, and dropping Sphinx for [https://zensical.org/docs/setup/extensions/mkdocstrings/ mkdocstrings]
* Discussion with Vaclav Petras on Windows builds and Fable:
** The nsis installer had a change to do (as debugged last year by me in [https://github.com/OSGeo/grass/issues/5663 #5663]), but we don't know how to do it well. We suggested to let Anthropic's Fable try to do it before it stopped being included in the Claude subscription.
** For us to try out the fixed nsis installer script, Fable should be able to create the installer in CI. It is being tried in [https://github.com/echoix/grass/pull/664 echoix#664]/[https://github.com/wenzeslaus/grass/pull/12 wenzeslaus#12]
** Also suggested to use Fable to attempt to solve issues in a pending Sphinx PR that we were stuck for too long, (Stcuk PR: [https://github.com/OSGeo/grass/pull/7526 #7526], result: [https://github.com/wenzeslaus/grass/pull/11 wenzeslaus#11])

* Discussed with Stefan Blumentrath:
** temporal init, choice of his PR or another contributor
** Discussed AI findings on various files accumulated in the last weeks: most are valid and should be filed.

* Worked on the last sscanf CodeQL alert, for [https://github.com/OSGeo/grass/pull/7673 #7673]
* Tested out windows standalone installer built in CI [https://github.com/echoix/grass/pull/664 echoix#664]. Almost works, as it installs, but it doesn't start because of a path error. Wrote some notes about windows compilation in CI in relation to addons in Vashek's google doc.
* Wrote notes on the windows build script having two versions, where OSGeo4W uses a different one than the one we use in CI for our tests, and they diverged

** Commented on an issue closed today [https://github.com/OSGeo/grass/issues/1313 #1313] about cppcheck: cppcheck could be useful to cover a bit more configuration combinations, but as discussed, only being to compile would only get us so far without testing.

GRASS Community Meeting San Michele 2026

[[File:Sanmichele.png|frameless|center|1000px|San Michele all'Adige]]

{{toc|right}}

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.

== Agenda ==

Agenda is forthcoming.

== 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 ==

''Participation is free of charge''. 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]

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 ==

* ''How was it last time?''
** Splendid! See [[GRASS Developer Summit Raleigh 2025]]!
* ''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''.
* ''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.

GRASS GSoC Ideas 2026

2026-02-05T09:05:30Z

Sbl: /* Ideas */

== 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.

=== 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

=== 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.

=== 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.

* Mentors: Vaclav Petras
* Co-mentors: ?
* Proposed by: Vaclav Petras
* Project length: Large (350 hours)
* Rating: medium
* Requirements:

=== 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.
