Overview
The Google Earth Visualization extenstion aims to allow the generation of Google Earth placemark files out of user data. The Google Maps API geocoding service is used to resolve addresses to coordinates.
Note: Make sure you read the Google Maps API Terms of Service before using this project.
Alternative Approach
An alternative, and likely better approach (I haven't actually tried it, so I would be interested to hear feedback on it from those that have tried it), would be to use Jaspersoft ETL with the tGoogleMapLookup Component available on the TalendForge
