Welcome to GRASS-Wiki.
The Geographic Resources Analysis Support System, commonly referred to as GRASS, is a Geographic Information System (GIS) used for geospatial data management and analysis, image processing, graphics/maps production, spatial modeling, and visualization. GRASS is currently used in academic and commercial settings around the world, as well as by many governmental agencies and environmental consulting companies. GRASS WIKI offers the official community platform of the GRASS GIS project.
On this Wiki, you can get and contribute GRASS related information, documents and add-ons programs.
