QGIS is a great, free, geographic information system for the desktop.

Analytical capability to go with the user-friendliness of this software is provided by a plugin system interfacing to several external tools. We plan to add a common framework, so every tool will fit in, and all tools could be used either individually or chained together.

In particular, this project aims at the creation of a QGIS plugin that makes it possible to run the versatile System for Automated Geoscientific Analysis (SAGA GIS) modules from Quantum GIS. This plugin generates a GUI on-the-fly and runs the modules using the SAGA Python API, i.e. automates the process of information exchange between QGIS as a end-user interface and SAGA as an analytical tool.

Installation & Usage

While this software is in development, and may not yet meet your production needs, if you want to help testing the interface to SAGA, you'll need to install a recent version of QGIS and SAGA and then download two plugins using the built-in Plugin installer.

Have a look at the SAGA Interface HOWTO for longer installation and usage instructions. Thanks!

Feedback & Support

Please, don't hesitate to send your information, criticism or praise through any of the channels below:


If you are developer thinking of providing support for your processing library to QGIS, you may want to read the introductory Developer's Tutorial, the framework's API and/or the design document (a bit outdated, but still relevant). The framework is currently written in Python, but a port to C++ is planned.

In regards to QGIS, its C++ API, the PyQGIS "cookbook" and the developer's manual can be valuable resources.
