The next geographical mapping startup, SpatialKey [spatialkey.com] is marketed as a "next generation Information Visualization, Analysis and Reporting System". It is specifically designed to help organizations quickly assess location-based information to allow for decision making processes and reporting requirements. There are several online demos available, ranging from "Wal-Mart store openings (1962 - 2005)" to "San Antonio prostitution arrests (January, 2006 - July, 2007)"
In practice, users can view and overlay all sorts of "geo-temporal data" (data with recorded location and time information) and generate time slices of the data, much like a moving weather map. The current visualization templates include three different map rendering techniques: heat map, heat grid and graduated circles.
