This is an old project that Andy Turner and I collaborated on sometime ago. When Google Code closed I pulled it over to github as it might be useful one day.

It implements a variety of spatial cluster detection methods such as GAM, Besag & Newell, Random circles using GeoTools. There is an initial attempt at a GeoServer WPS process but I’m not sure it will still work.

If you are thinking but I have a heatmap plugin that already works you need to consider the following XKCD cartoon :

Why Heatmaps are bad!\ Why Heatmaps are bad!

And if you feel then need for something more authorative than XKCD see what the CartoNerd has to say about heat maps. Hint he’s against.
