In this article, I want to look at a GIS option available for Linux—specifically, a program called SAGA (System for Automated Geoscientific Analyses). SAGA was developed at the Department of Physical Geography in Germany. It is built with a plugin module architecture, where various functions are provided by individual modules. A very complete API is available to allow users to extend SAGA's functionality with newly written modules. I take a very cursory look at SAGA here and describe a few things you might want to do with it.
Installing SAGA should be as easy as looking at the software repository for your favourite distribution.
