Johannes’ second article, “Creating Heat Maps with Virtual Earth and SQL Server 2008” illustrates how to take information from SQL Server 2008 (he’s quite the expert) and create a rasterized heat map which can then be geo-annotated (using Map Cruncher or based on theVirtual Earth Tile System documentation) and overlain atop a Virtual Earth-based application. Although there is another layer (and, there can be many layers!) this map is still interactive in that you can overlay vector information or grab lat/lons for spatial analysis.
Lastly, a while back Danyel Fisher from Microsoft Research published “Hotmap: Looking at Geographic Attention” which discussed the create of a heat map tool for tracking web site traffic. In fact, there’s a demonstration of this application online dubbed, “Hotmap: The Use of Virtual Earth” which “shows where people have looked at when using Virtual Earth, the engine that powers Live Search Maps: the darker a point, the more times it has been downloaded.”
