SAGA -- System for an Automated Geo-scientific Analysis -- is a free Geographical Information System ( GIS ).
One can understand SAGA as a geographic information system with a special 'Application Programming Interface' ( API ) for geographic data processing. This API makes it easy to implement new algorithms and exempts the developer from hassle programming overhead like user-interface design or file-io. The SAGA API supports grid data like digital terrain models and satellite images, vector data, and tables.

Since the release of SAGA there is a growing collection of SAGA-Modules, in areas of digital terrain analysis, geo-statistics, image processing and process simulation. SAGA is released under GNU Public License ( GPL )
