The Geographic Resources Analysis Support System
(, commonly referred to as GRASS GIS, is an
Open Source Geographic Information System providing powerful raster,
vector and geospatial processing capabilities in a single integrated
software suite. GRASS GIS includes tools for spatial modeling,
visualization of raster and vector data, management and analysis of
geospatial data, and the processing of satellite and aerial imagery.
It also provides the capability to produce sophisticated presentation
graphics and hardcopy maps. GRASS GIS has been translated into about
twenty languages and supports a huge array of data formats. It can be
used either as a stand-alone application or as backend for other
software packages such as QGIS and R geostatistics. It is distributed
freely under the terms of the GNU General Public License (GPL). GRASS
GIS is a founding member of the Open Source Geospatial Foundation
