What geo standards does Google Fusion Tables use?
The Intensity Map visualization uses a controlled vocabulary of country names and 2-letter country codes, as specified by the ISO 3166 standard. See the Wikipedia reference page. http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2#Officially_assigned_code_elements Fusion Tables assumes that latitude and longitude numbers are in Decimal Degrees. Lat-long info in Degree-Minutes-Seconds should be converted to Decimal Degrees. Like all other Google mapping tools, Google Fusion Tables assumes the WGS 84 datum. If you know your location data is in a different datum, you’ll want to convert it first for the most accurate mapping.
