Abstract

Thematic maps using KML and KMZ are common for point and line features, but scarce for area features. We present a method and website for generation of the thematic map KMLs based on US Census geography. By taking advantage of various preprocessing and indexing methods, thematic maps viewable in any KML compliant viewer (eg, Google Maps, Google Earth, or ArcGIS Explorer) can be generated very quickly. Our implementation covers counties, census tracts, and zip code tabulation areas for the entire United States and its territories and 31 socio-demographic variables.
