Spatial Analysis with GeoDa and GeoViz

GeoDa is a powerful Open Source GIS, designed specifically for analysis using spatial statistics.  GeoDa enables users to create thematic maps, and a series of charts that are interlinked.  The example below explores unemployment rates from 1960-1990 using GeoDa.

Another useful Open Source GIS is GeoViz.  GeoViz allows users to create bivariate maps and engaging scatterplots.  The example below explores unemployment and family poverty from 1960-1990 using GeoViz.

Another GeoViz example is shown below.
