<p>SAGA GIS (System for Automated Geoscientific Analyses) is a free and
open source geographic information system used for editing and analysing
spatial data. It includes a large number of modules for the analysis of
vector (point, line and polygon), table, grid and image data. Among
others the package includes modules for geostatistics, image
classification, projections, simulation of dynamic processes (hydrology,
landscape development) and terrain analysis. The functionality can be
accessed through a GUI, the command line or by using the C++ API.</p>
<p>SAGA GIS has been in development since 2001, and the centre of SAGA development is
located in the Institute of Geography at the University of Hamburg, with
contributions from the growing world wide community.</p>
<p>SAGA comes with a comprehensive set of free modules, most of them
published under the GPL (332 modules in 45 libraries).</p>
