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.
