In a joint effort, Icelandic GeoSurvey (ISOR) and ThinkGeoEnergy publish the Global Geothermal Power Map. The map was created using data from various sources. Background, place names and boundaries are from the Natural Earth Data & Etopo2. Locations of geothermal sites are compiled by ThinkGeoEnergy and Iceland GeoSurvey. Production capacity is from the International Geothermal Association (IGA) database.
An electronic version of the map is avaliable at: www.thinkgeoenergy.com/map
The map is currently only available in a limited number of copies, but might be available for sale in the near future.
