GeoDa - Free Spatial Data Analysis Software

GeoDa - Spatial Data Analysis Software:

This was a nifty free software app that I wasn't expecting to stumble across. A nice list of recommended GIS software can be found at the mapz: a gis librarian blog.

The free program provides a user friendly and graphical interface to methods of descriptive spatial data analysis, such as spatial autocorrelation statistics, as well as basic spatial regression functionality. The latest version contains several new features such as a cartogram, a refined map movie, parallel coordinate plot, 3D visualization, conditional plots (and maps) and spatial regression.
