Geographic Resources Analysis Support System (GRASS GIS, or just GRASS) is a "free and open source Geographic Information System (GIS) software suite used for geospatial data management and analysis, image processing, graphics and maps production, spatial modeling, and visualization." As of 2015, the current stable release is 7.0.0.


GRASS has been in continuous development since the early 1980s. It is currently an OSGeo project.

It is being localised in various languages. Localisation in Arabic is in process. As of 2007 there was talk of a project in Ethiopia to translate GRASS in Amharic (no further information). GRASS designers have been interested in localisation in Swahili for some time (this language mentioned on their current website as one they would like to localize in).
