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 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 initial 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.
  • Address issues discussed last year about GRASS-R integration: https://github.com/rsbivand/rgrass/discussions/78
  • Discuss mailing list (mailman) vs discourse (forum)
  • Simplify working with GRASS 8.4+ in Python wiki page, then improve here on GS
  • Create release artifacts by GitHub CI (for inspiration, see libgeotiff and GEOS)
  • Meals: Lunch and dinner provided unless noted otherwise.

Map

Prague, the capital of Czechia (Czech Republic) has an international airport. It's location in the middle of central Europe makes it easily reachable by train, bus or car. The city itself has great public transportation.

  • Bring power connector adapter if needed (Czech Republic: 230V, 50Hz, Type C Europlugs are common and also Type E)
  • Install git and the compiler tools, and come with a working GRASS development environment if possible. See here for details.

FAQ

  • How was it last time?
  • 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!
  • 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?
