6 Geographic Resources Analysis Support System, commonly referred to as
7 GRASS GIS, is a Geographic Information System (GIS) used for geospatial
8 data management and analysis, image processing, graphics/maps produc‐
9 tion, spatial modeling, and visualization. GRASS is currently used in
10 academic and commercial settings around the world, as well as by many
11 governmental agencies and environmental consulting companies.
12 This reference manual details the use of modules distributed with Geo‐
14 graphic Resources Analysis Support System (GRASS), an open source (GNU
15 GPLed), image processing and geographic information system (GIS). Go
