Welcome to State Geothermal Data

State Geological Surveys in the U.S. have thousands of databases, directories, and 85,000+ geologic maps that collectively constitute a national geoscience data “backbone” for research and applications.

The State Geothermal Data project, organized by the Association of American State Geologists (AASG) with funding from the Department of Energy, brings data from all 50 States into the National Geothermal Data System (NGDS). We are digitizing at-risk, legacy geothermal-relevant data and publishing existing digital data by exposing databases and directories to the network. A limited amount of new data in areas lacking critical information is also being collected.

The Association of American State Geologists (AASG) represents the State Geologists of the 50 United States and Puerto Rico. Founded in 1908, AASG seeks to advance the science and practical application of geology and related earth sciences in the United States and its territories, commonwealths, and possessions.
