GRASS is released under the GNU General Public License (GPL), and it can be used on multiple platforms, including Mac OS X, Microsoft Windows (natively or with optional Cygwin tools) and Linux. Users can interface with the software features through a graphical user interface (GUI) by using the internal GUI with X Window System or by "plugging into" GRASS via Quantum GIS. They can also interface with the modules directly through the modified version of the shell that the application launches or by calling individual modules directly from a preferred shell (this latter method requires the setting of several environment variables). The recent GRASS 6 release introduces a new topological 2D/3D vector engine and support for vector network analysis. Attributes are managed in .dbf files or SQL-based DBMS such as MySQL, PostgreSQL/PostGIS, and SQLite. The system is capable of visualizing 3D vector graphics data and voxel volumes. GRASS supports an extensive range of raster and vector formats through the binding to GDAL/OGR libraries, including OGC-conformal (Open Geospatial Consortium) Simple Features for interoperability with other GIS. It also supports Linear Reference System. The GRASS Development Team is a multi-national group consisting of developers at numerous locations. GRASS is one of the eight initial Software Projects of the Open Source Geospatial Foundation. |
