The National Geologic Map Database (NGMDB) is a congressionally mandated project led by the U.S. Geological Survey and Association of American State Geologists. The purpose is to build a national archive of maps and related data about geology, hazards, earth resources, geophysics, geochemistry, geochronology, paleontology, and marine geology. You can access it through a searchable catalog that contains information on over 88,000 geoscience maps and reports dating back to the 1800s, with links to hundreds of publishers. |
