GAM: Cluster hunting software (v2.0 GAM/K)
Centre for Computational Geography
University of Leeds
The Geographical Analysis Machine (GAM) is an attempt at automated exploratory
spatial data analysis of point or small area data that is easy to understand.
The purpose is to answer a simple practical question; where are clusters in geographical
data? Please note it is an exploratory analysis and does not prove existence - clusters
may, for example, be down to pockets of poor data or, very unusually, be due to
just the random scattering of occurrences.
The software, which can be downloaded below, is written in Java and requires
the Java Runtime Environment (JRE) to run. Try running it
first, and if this doesn't work, install the JRE. To run the software in Windows, right click on the
file and pick Open With... and Java(TM) 2, or similar.
If you have any trouble, you can find a simple tutorial
The software was originally developed in online format for the
"Smart Spatial Analysis" project. While the original version is
now offline, you can still read more about how the system works
and what it does on the project pages.

On the 16th of December 2010 a Google code repository was set up to refactor the Java code for spatial cluster detection. The repository is located at the following URL:
