\fBGeographic Resources Analysis Support System\fR, 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.
.PP
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).
