* have been working on developing a workflow-tool tutorial template that facilitates GRASS learners who tend to 'jump in' or have a 'choose your own adventure' approach to learning GRASS (i.e., want to use their data for their study area for their objective from the start). The structure of the tutorial template is a concise, basic, general description/instructions of the workflow with optional links to pertinent explanatory/deeper dive content (e.g., plain language explainers of the tool, options, defaults, etc.) in a variety of formats (e.g., captioned images, short tool demo videos (30 sec to 2 min)) in addition to the more comprehensive resources available (e.g. documentation, examples, tutorials). The main motivation for this approach is to help new and occasional GRASS users avoid some of the common pitfalls and to learn how to find workarounds for some of the unanticipated challenges they may encounter with their specific datasets or use cases so that they can learn as they go. Another motivation for this approach is to facilitate the translation, extension, and updating of workflow tutorials by the community over time (e.g., providing audio and closed captioning for one of the tool-demo videos in another language, replacing an outdated GUI demo with one for the current release, or incorporating a new add-on as an option in the workflow).

* my focus this week is on developing a draft/test tutorial (in Quarto) for a standard hydrological modelling workflow that begins with the crucial pre-work of how to figure out the appropriate project/location, etc. as well as considerations of some of the downstream impacts of resolution, extent, region etc. It may not be ready for sharing by the end of the week, but suggestions and advice are welcomed in advance.

* have been working on developing a workflow-tool tutorial template that facilitates GRASS learners who tend to 'jump in' or have a 'choose your own adventure' approach to learning GRASS (i.e., want to use their data for their study area for their objective from the start). The structure of the tutorial template is a concise, basic, general description/instructions of the workflow with optional links to pertinent explanatory/deeper dive content (e.g., plain language explainers of the tool, options, defaults, etc.) in a variety of formats (e.g., captioned images, short tool demo videos (30 sec to 2 min)) in addition to the more comprehensive resources available (e.g. documentation, examples, tutorials). The main motivation for this approach is to help new and occasional GRASS users avoid some of the common pitfalls and to learn how to find workarounds for some of the unanticipated challenges they may encounter with their specific datasets or use cases so that they can learn as they go. Another motivation for this approach is to facilitate the translation, extension, and updating of workflow tutorials by the community over time (e.g., providing audio and closed captioning for one of the tool-demo videos in another language, replacing an outdated GUI demo with one for the current release, or incorporating a new add-on as an option in the workflow).

* my focus this week is on developing a draft/test tutorial (in Quarto) for a standard hydrological modelling workflow that begins with the crucial pre-work of how to figure out the appropriate project/location, etc. as well as considerations of some of the downstream impacts of resolution, extent, region etc. It may not be ready for sharing by the end of the week, but suggestions and advice are welcomed in advance.

19 May
* discussed a novice user issue with 'moving' vector data from one location to another with Vero and learned a neat GUI option
* revised and added workflow tutorial text

=== Shonil Sateesh Bhide | NC State University ===

* CI optimization

=== Huidae Cho | New Mexico State University ===

* CMake, conda, CI, Mentoring

=== Edouard Choinière ===

* Quick ideas, way too much for a week: Helping others (may take a reasonable part of the time), managing CI, setting up localization template updating workflow, backporting tool? Pytest/coverage improvements? Discuss and design other projects, to work on during the year. Open to change on other priorities once there, anything that is useful. Maybe make a little progress on high dpi GUI, especially on Windows.

* Weekend before sprint:
** Clear up Renovate PRs to not use CI time during the sprint, reviewing and merging: [https://github.com/OSGeo/grass/pull/5664 #5664], [https://github.com/OSGeo/grass/pull/5665 #5665], [https://github.com/OSGeo/grass/pull/5666 #5666], [https://github.com/OSGeo/grass/pull/5667 #5667], [https://github.com/OSGeo/grass/pull/5668 #5668]
** PR to avoid some CI run time for the sprint: [https://github.com/OSGeo/grass/pull/5670 #5670]
** Reviewed open PRs for PRs that were mergeable before the sprint, updated outdated PRs to avoid having it needing CI time during sprint.

== Daily tasks for participants ==

* List all the things you are working on in the Participant reports section below. Update the list each day. Include things you work on with other people.
* If you want to discuss something with the whole group, add yourself to a Self-organized feedback sessions slot in the schedule above or tell Vaclav (Vashek) Petras.
* For people with triage access and above: If you are or will be working on an issue or on a PR which is not originally submitted by you, assign yourself to the issue or PR. (You can unassign yourself later if you change your mind.)

== Participant reports ==

Per-person reports from the meeting.

=== Giuseppe Amatulli | Yale University ===

* Testing r.watershed and r.stream.* for handling large datasets

=== Veronica Andreo | CONICET - Instituto Gulich ===

* Plan:
** Review of temporal tutorials to push them to tutorials
** Sync branding between GRASS and tutorials websites
** GRASS project admin stuff
** Understand new docs contribution and building workflow
** Interface with R
* [https://github.com/veroandreo?tab=overview&from=2025-05-12&to=2025-05-24 GitHub contributions]
* Website footer enhancement
* Fix descriptions and their display in the tutorials website
* Fix GRASS page on OSGeo website [https://www.osgeo.org/projects/grass-gis/]
** Changed logo, removed GIS from the name, fixed old links
* Social media post
* Discussion about hyperspectral with Alen and Anna

=== Abdullah Azzam | New Mexico State University ===

* r.runoff

=== Michael Barton | Arizona State University ===

* POSE related activities

=== Laura Belica | NC State University ===

* have been working on developing a workflow-tool tutorial template that facilitates GRASS learners who tend to 'jump in' or have a 'choose your own adventure' approach to learning GRASS (i.e., want to use their data for their study area for their objective from the start). The structure of the tutorial template is a concise, basic, general description/instructions of the workflow with optional links to pertinent explanatory/deeper dive content (e.g., plain language explainers of the tool, options, defaults, etc.) in a variety of formats (e.g., captioned images, short tool demo videos (30 sec to 2 min)) in addition to the more comprehensive resources available (e.g. documentation, examples, tutorials). The main motivation for this approach is to help new and occasional GRASS users avoid some of the common pitfalls and to learn how to find workarounds for some of the unanticipated challenges they may encounter with their specific datasets or use cases so that they can learn as they go. Another motivation for this approach is to facilitate the translation, extension, and updating of workflow tutorials by the community over time (e.g., providing audio and closed captioning for one of the tool-demo videos in another language, replacing an outdated GUI demo with one for the current release, or incorporating a new add-on as an option in the workflow).

* my focus this week is on developing a draft/test tutorial (in Quarto) for a standard hydrological modelling workflow that begins with the crucial pre-work of how to figure out the appropriate project/location, etc. as well as considerations of some of the downstream impacts of resolution, extent, region etc. It may not be ready for sharing by the end of the week, but suggestions and advice are welcomed in advance.

19 May
* discussed a novice user issue with 'moving' vector data from one location to another with Vero and learned a neat GUI option
* revised and added workflow tutorial text

=== Shonil Sateesh Bhide | NC State University ===

* CI optimization

=== Huidae Cho | New Mexico State University ===

* CMake, conda, CI, Mentoring

=== Edouard Choinière ===

* Quick ideas, way too much for a week: Helping others (may take a reasonable part of the time), managing CI, setting up localization template updating workflow, backporting tool? Pytest/coverage improvements? Discuss and design other projects, to work on during the year. Open to change on other priorities once there, anything that is useful.

Lead to PRs addressing Windows blockers: [https://github.com/OSGeo/grass/pull/3850 #3850] and [https://github.com/OSGeo/grass/pull/3853 #3853], which I tested on my fork combined with my changes highlighting the bugs.
* Reviewing of PRs, managing CI during the sprint (restarting transient failures, finding inefficiencies, queueing jobs before and after active periods).
* Maintaining code quality CI and pre-commit. Example: Flake8 fails with Python 3.12 in pre-commit, as it is way outdated, harming contributions of the sprint's participants. Bumping to a new version has other failures and dependent changes needed.

* With Vaclav Petras: reviewing backportable PRs, and designing the requirements and it's implementation of a automated backport solution with GitHub actions. Prioritized to work on the implementation after the sprint, as other features affecting productivity during the sprint should be worked on.
* With Vaclav Petras: Discussing release notes generation improvements, deciding on new labels and classification, adjusting and improving titles regexes. Designed a process to validate PR that PR titles are classified correctly automatically, to greatly simplify future releases. This lead to Vaclav creating the validation function in [https://github.com/OSGeo/grass/pull/3824 PR #3824]. Implementation of validation workflow on PR creation and title changes will follow. PRs related to these decisions also include: [https://github.com/OSGeo/grass/pull/3823 #3823], [https://github.com/OSGeo/grass/pull/3829 #3829]
* Clarifying our supported languages standard support with Vaclav Petras and when changes should be made, leading to reduction of C/C++ CI usage in [https://github.com/OSGeo/grass/pull/3846 #3846]. Postponed checking of newer C++23 until Ubuntu 24.04 builds with newest GCC toolchain are included in CI.
* Helping Alen Mangafić with a local build to run alongside jupyter and conda environment.
* Reviewing Chung-Yuan Liang's PR, then assisting him multiple times with git operations, argparse, and unittest-related problems when programming. Sample of resulting PRs: [https://github.com/OSGeo/grass/pull/3835 #3835]
* Review and ajust repository's configuration to prevent some noticed problems, including pull request title/commit details (with Markus) and ruleset permissions related to branch creation (with Vaclav).

* With Vaclav Petras: reviewing backportable PRs, and designing the requirements and it's implementation of a automated backport solution with GitHub actions. Prioritized to work on the implementation after the sprint, as other features affecting productivity during the sprint should be worked on.
* With Vaclav Petras: Discussing release notes generation improvements, deciding on new labels and classification, adjusting and improving titles regexes. Designed a process to validate PR that PR titles are classified correctly automatically, to greatly simplify future releases. This lead to Vaclav creating the validation function in [https://github.com/OSGeo/grass/pull/3824 PR #3824]. Implementation of validation workflow on PR creation and title changes will follow. PRs related to these decisions also include: [https://github.com/OSGeo/grass/pull/3823 #3823], [https://github.com/OSGeo/grass/pull/3829 #3829]
* Clarifying our supported languages standard support with Vaclav Petras and when changes should be made, leading to reduction of C/C++ CI usage in [https://github.com/OSGeo/grass/pull/3846 #3846]. Postponed checking of newer C++23 until Ubuntu 24.04 builds with newest GCC toolchain are included in CI.
* Helping Alen Mangafić with a local build to run alongside jupyter and conda environment.
* Reviewing Chung-Yuan Liang's PR, then assisting him multiple times with git operations, argparse, and unittest-related problems when programming. Sample of resulting PRs: [https://github.com/OSGeo/grass/pull/3835 #3835]

The ''GRASS GIS Community Meeting'' for contributors and developers will be happening from '''June 14 to June 19, 2024''' in Prague, Czechia.

[[File:Prague-Community-Meeting-2023-crop.jpg|500px|frameless|center]]

== Sponsor us! ==

We welcome financial contributions to support the meeting and we are looking for sponsors to cover costs such as meals or to help reducing travel and accommodation expenses for GRASS developers who volunteer their time. If you are interested in sponsoring the GRASS Community Meeting, please go to:

::: '''[https://opencollective.com/osgeo/projects/grass/contribute OpenCollective]'''

Any surplus at the end of the event will be used for future activities of the GRASS GIS project such as the [[Student Grants|Student Grant program]].

This GRASS Community Meeting is a great occasion for you to support the development of GRASS. With your contribution you'll enable more developers to meet. Community meetings are important opportunities for developers to discuss, fix bugs, plan the direction for the project and work on new features. The developers and other contributors or their employers are donating their valuable time, so it would be great if funding can be made available from within the community to cover out-of-pocket expenses. All of the work that takes place at the community meeting will be directly contributed back into the GRASS project to the benefit of everyone who uses it. Note that while we have our general plan, we can't accept any earmarked donations, i.e., we can't make any promises for a specific work to be done, please contact specific developers or support commercial providers for that.

We are grateful to the following sponsors for their support and commitment!

* U.S. National Science Foundation, award 2303651. (Travel for 5 participants and their time, event venue.)

[[File:NSF Official logo.png|none|left|200px|alt=Logo of US NSF|U.S. National Science Foundation]]

[[File:FOSSGIS_eV_logo.png|none|left|400px|alt=Logo of FOSSGIS e.V.|FOSSGIS e.V.]]

* In-kind contributions will be acknowledged here.
* Personal time and/or financial contributions will be acknowledged here.

== Purpose ==

The ''GRASS GIS 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 GIS project and the interfaces to QGIS, GDAL, PostGIS, R, OGC Services and others.

In this meeting, building on momentum from the 40th birthday meeting, we will continue the revisions of the maintenance processes and infrastructure - a process which highly benefits from the current maintainers being in one place (and time zone). Topics which require highly synchronous collaboration will be included such as Markdown documentation and CMake build transitions. Other contributors are expected to enhance existing tools and their documentation. A [https://grass.osgeo.org/news/2023_08_13_grass_community_meeting_prague_june_2023_report/ press release] gives an overview of last year's event.

We do require participants to work on GRASS GIS 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.

For the detailed agenda and individual's plans, see below.

== Agenda ==
These are some of the identified project priorities:
* Develop the project roadmap to better communicate project vision and priorities.
* Discuss the GRASS GIS integration with QGIS with its maintainers to identify next steps.
* Test the CMake and conda packaging implementations.
* Finalize the HTML to Markdown documentation conversion.
* GSoC students will showcase their projects and seek feedback. We also search for fostering their engagement with community members participating in the meeting and others that want to join online.
* Test and review onboarding documentation for developers, maintainers and other contributors.
* Develop use cases and tutorials on the use and integration of STAC related modules into data processing workflows.
* Get feedback on ongoing GRASS website UX improvements and add missing content.

* '''How was it last time?'''
** Splendid! See [[GRASS Community Meeting Prague 2023]]!
* ''Is the meeting just a coding event?''
** It is mainly a coding and documentation event. It is a working session for people who are already participants in the GRASS project and/or are committed to improving the GRASS project. Committed newcomers are welcome!
** On demand we can do some presentations of current working GRASS implementation and new upcoming features to spread the idea of Open Source GIS software.
* ''Is the GRASS Community Meeting for developers only?''
** No: anybody can help, with testing, checking out bugs and fixes, documentation and more.
* ''Where can I get help and more information about the community meeting?''
