The GRASS GIS team is organizing the GRASS GIS Community Meeting with contributors, power users and developers from June 2 to June 6, 2023 to celebrate GRASS GIS 40th birthday.
-
Prague 2013

Bonn 2018
Purpose
GRASS GIS Community Meeting is a great occasion for folks to support the development by actively contributing to the source code, documentation (manuals, wiki, tutorials), translations, website 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 desiring to celebrate with us the 40th GRASS GIS birthday!!
In this meeting, we will work on GRASS GIS and integrations with related OSGeo projects. We will revise connection to QGIS to make it easier to maintain, and we will migrate the build to CMake to improve Windows builds including PDAL support. Furthermore, we will move documentation to Markdown to make it easier to contribute to and we will add images and examples for tools and workflows which still miss them. Finally, we will automate and document maintenance processes to reduce the burden on maintainers and thus improve the project sustainability.
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. 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 at that time given their skills and time available.
For the detailed agenda and individual's plans, see below.
Sponsors
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 see our
Any surplus at the end of the event will used for future activities of the GRASS GIS project such as the successful student mini 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. Please see below for the detailed agenda. The developers and contributors are donating their valuable time, so it would be great if in-kind 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.

Financial support: (partial) travel grants can be payed upon request thanks to our sponsors!
Agenda - What we plan to do
Note: The program is generally open for your ideas. Please write an email to the GRASS developer list to discuss your contribution.
During the meeting we will work on GRASS GIS on these tasks (please add more!):
- We will update and revise the GRASS GIS Integration with QGIS to simplify maintenance.
- Furthermore, we will migrate the compilation technology to CMake to significantly improve the Windows builds including PDAL support and become binary compatible with OSGeo4W.
- The extensive GRASS documentation will be converted from HTML to Markdown to facilitate future collaboration.
- Pictures, examples and workflows will be added to the documentation where they are still missing.
- Software maintenance processes are automated and documented to reduce the burden on maintainers and thus improve the sustainability of the project.
This means that there are tasks from both the programming and documentation areas to appeal to a wide range of interested parties.
Further details about the action items you find here and below. Topics cover non-technical, semi-technical, and technical issues.

FAQ
- How was it last time?
- Very nice, see GRASS_GIS at OSGeo Virtual Community Sprint 2020!
- Is the GRASS Community 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.
- 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?
- Contact Martin Landa <landa.martin at gmail.com>
Report and press release
TBD: After the event :-)
We'll esp. craft a report for our sponsors.
