This is not exactly an answer to your question, but you might be interested in some Google Maps that I created to display information stored in Mathematica. The most basic one simply displays a marker at the capital of each county; clicking on the marker displays information about the country. You can view it here: http://facstaff.unca.edu/mcmcclur/GoogleMaps/Countries/ I also generated several Google Maps that use projections other than Google's default Mercator projection. The Google Maps API provides tools to define your own projection but it is necessary to generate your own map tiles to use it. The tiles in these maps were generated with Mathematica using the FullPolygons provided with CountryData. There's only five zoom levels, but this gets the idea across. The projection maps are here: http://facstaff.unca.edu/mcmcclur/GoogleMaps/Projections/ Finally, I wrote a package that converts a GPX file directly to a GoogleMap: http://facstaff.unca.edu/mcmcclur/GoogleMaps/GPXToGoogleMap/ So, clearly, it's possible to display most of Mathematica's data directly in a Google Map.
