Description
GRASS (Geographic Resources Analysis Support System) is a Software for performing spatial analysis. 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.

GRASS was originally developed in the beginning of the 1980s by the US Army Construction Engineering Research Laboratories (USA-CERL) and was published as a public domain software. When the USA-CERL withdrew from the GRASS development, an international developer team took over this work. Since 1999 GRASS has been published as a free software under the terms of the GNU General Public Licence.

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