GRASS GIS 7.6.0 Reference Manual

6       Geographic  Resources  Analysis Support System, commonly referred to as
7       GRASS, 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.

13       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
