GRASS

Geographic Resources Analysis Support System (GRASS) is a Geographic Information System (GIS) used for geospatial data management and analysis, image processing, graphics/maps production, spatial modeling, and visualization.

It consists of more than 350 modules for processing vector (2D/3D), raster and voxel data. Many interfaces to other programs in related domains like geostatistics, databases, mapserver and even other GIS software exist. 

It can serve as a Desktop GIS and as the backbone of a complete GIS infrastructure.

It was created in the 1980s by the US Army Corps of Engineers, Construction Engineering Research Laboratory (USA/CERL) and has been enhanced by many others. 

GRASS is currently used in scientific applications, commercial settings and by public officials all over the world.
