GRASS (the Geographic Resources Analysis Support System) is a software raster- and vector-based GIS (Geographic Information System), image processing system, graphics production system, and spatial modeling system. It contains many modules for raster data manipulation, vector data manipulation, rendering images on the monitor or paper, multispectral image geocoding and processing, point data management and general data management. It also has tools for interfacing with digitizers, scanners, and the PostgreSQL, DBF, and ODBC connected databases. In the UNIX environment GRASS operates through a shell and a menu bar, and can also work under the X Window System. For MS-Windows a generic display driver is available.

database code. Some improvements have been
backported from the GRASS 6.3
development branch, in which new development
continues at a strong pace
of approximately one code commit every hour,
including major work on a
new cross-platform wxPython GUI and a native MS
Windows port.
