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 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.
