GRASS GIS 6.4.3 Reference Manual
Geographic Resources Analysis Support System, commonly referred to as GRASS, is a <a
href="http://en.wikipedia.org/wiki/Geographic_information_system">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 GPL'ed), image processing and
geographic information system (GIS). Go to display introduction
