The GRASS GIS project is a volunteer-based organization, it is an affiliated project and founding member of the Open Source Geospatial Foundation (OSGeo).
There is no cost to participate in the project itself or to use the software.
But with our own budget we can produce even better software and documentation for you. And if you don’t have time to contribute, maybe a (small) donation makes you feel better when using GRASS GIS.
The donations are controlled in full transparency by the GRASS Project Steering Committee (PSC). Funds offered to GRASS GIS are used to sponsor general GRASS GIS efforts, especially:
Also bug fixing may be financed - community polls will identify outstanding problems which cannot be fixed on a voluntary basis; or specific bug-bounties can be arranged (please contact us first).
Many thanks to all our supporters and sponsors throughout the years!
Please refer to the List of Sponsors in the GRASS GIS Wiki for details.
