GRASS GIS 8.3.0 Reference Manual

       Geographic  Resources  Analysis  Support  System,  commonly referred to as GRASS GIS, is a
       Geographic Information System (GIS) used for  geospatial  data  management  and  analysis,
       image  processing, graphics/maps production, spatial modeling, and visualization. GRASS is
       currently used in academic and commercial settings around the world, as well  as  by  many
       governmental agencies and environmental consulting companies.

       This  reference  manual  details  the use of modules distributed with Geographic Resources
       Analysis Support System  (GRASS),  an  open  source  (GNU  GPLed),  image  processing  and
       geographic information system (GIS).  Go back to help overview
