SAGA GIS 2.1.2

The System for Automated Geo-scientific Analysis and Geographic Information System
SAGA (System for Automated Geoscientific Analyses) GIS (Geographic Information System) is an open source, cross-platform and free graphical and command-line software that has been designed for an effective and easy implementation of spatial algorithms.

Features at a glance

The project boasts an object-oriented system design, provides a comprehensive and growing collection of geoscientific methods, a modular structure that allows you to develop framework-independent functions, as well as a convenient and easy-to-use GUI (Graphical User Interface) that features intuitive data management support and numerous visualization and analysis options.

Among other features, we can mention support for over 450 functions for geographical data analysis, support for terrain analysis, scripting via command-line supporting the Java, Python and R programming languages, cartographic and georeferencing projections, geographical statistics, image analysis, vector tools, a powerful API that offers great support for geodata handling.

In addition, the software comes pre-loaded with several vector tools, including buffer zones, raster to vector conversion and clipping, numerous terrain analysis tools like classification, morphometry, illumination and hydrology, a wide range of image analysis tools, such as OBIA (Object Based Image Analysis), FFT (Fast Fourier Transform), PCA (Principal Component Analysis), supervised classification and filters.

Several geostatistics functions are also provided, such as universal and ordinary Kriging, GWR (Geographically Weighted Regression) and variograms, as well as grid interpolation of scattered point data, splines, triangulation and IDW (Inverse Distance Weighted).

Under the hood and supported OSes

The software is written entirely in the C++ programming language and uses the wxWidgets framework for the graphical user interface (GUI). It has been designed from the offset as a cross-platform software that supports the GNU/Linux, FreeBSD and Microsoft Windows operating systems. Both 64-bit and 32-bit hardware platform are supported at this time. It is available for download as a universal sources archive, as well as a pre-built binary package for all GNU/Linux OSes.

What's New in This Release:
  • For this version some efforts have been made to make the graphical user interface more smooth and user friendly. New features include the display of a North arrow, scale bar, and geographic coordinate grids for map views. Enhanced options for interactive vector data editing have been added. Modules are now generally addressed as 'tools' and the modules menu has been renamed to 'Geoprocessing'. Besides this many bug fixes could be applied and you will also find a number of tools, which for sure will be quite interesting for some of you. For example a complete tool set focusing on slope stability has been contributed by Andreas Guenther.
