Almost a year ago, I posted on Bjorn Sandvik’s Thematic Mapping Engine, which can plot data thematically in Google Earth as:
- Choropleth
- Prism
- Proportional symbol
- Pie chart
At the time, you could only use a limited number of pre-packaged datasets. Bjorn has just announced the Thematic Mapping Engine API, a Javascript library that lets you do thematic mapping in the Google Earth plugin with your own data (including online sources like Google Docs Spreadsheet). Still in beta, and Bjorn is looking for people to try it out (non-commercial use only). Documentation is a bit sparse right now, but if you look at the page source for example maps created with the API, it’s not too hard to figure out.
Thematic Mapping Engine API For Displaying Your Own Data In Google Earth looks like a great tool. Does one need a”paying” license for Google Earth to display the data?
Thanks.

Tough question. For personal, non-profit or non-commercial applications, almost certainly not. For business/profit applications, possibly for internal use, almost certainly for external use. Read the Google Earth Terms Of Use for the official take.
