SAGA GIS


System for Automated Geoscientific Analyses is a geographic information system computer program, used to edit spatial data. It is free and open-source software, developed originally by a small team at the Department of Physical Geography, University of Göttingen, Germany, and is now being maintained and extended by an international developer community.
SAGA GIS is intended to give scientists an effective but easily learnable platform for implementing geoscientific methods. This is achieved by the application programming interface. SAGA has a fast-growing set of geoscientific methods, bundled in exchangeable module libraries.
The standard modules are:
SAGA GIS is an effective tool with user friendly graphical user interface that requires only about 10 MB disk space. No installation is needed, since SAGA GIS can be run directly from a USB thumb drive if desired.
SAGA GIS is available for Windows, Linux, and FreeBSD.
SAGA GIS can be used together with other GIS software like Kosmo and QGIS in order to obtain enhanced detail in vector datasets as well as higher-resolution map-production capabilities. SAGA GIS modules can be executed from within the statistical data analysis software R, in order to integrate statistical and GIS analyses.
