National and International Geology Data

This webpage covers geologic data and maps that are national in scope, generally 1:1,000,000 to 1:2,000,000 scale, as well as national funding and coordination programs and standards. It also includes a section for finding international geology data.

• GEODE: U.S. GEO-DATA Explorer
  Web application to access, view, and download information from worldwide geo-spatial databases containing a broad spectrum of data produced by the USGS and other government agencies. [has been down for maintenance]

• Mineral Resources On-Line Spatial Data
  Links to state and national geology, geochemistry, geophysics, and mineral resource maps and data.
   
• A Tapestry of Time and Terrain  A map that combines geology and topography. It resembles traditional 3-D perspective drawings of landscapes with the addition of a fourth dimension, geologic time, which is shown in color. Available for the lower 48 states and for North America.

U.S. Bureau of Land Management

• GeoCommunicator
  Interactive web maps of BLM activities related to mining, land use permits, rights-of-way and oil and gas leasing. May not contain data for Minnesota, but is useful for finding data in other states.
   

National Cooperative Geologic Mapping Program (NCGMP)

Run primarily by the U.S. Geological Survey, this program provides funding and direction for geologic mapping and modeling at the national, state and collegiate levels.

• NCGMP Homepage
• National Geologic Map Database
  A component of the NCGMP with links to the Geoscience Map Catalog, Geologic Names, and Mapping in Progress applications.
• Geologic Mapping Standards
   

International

• OneGeology
  An international initiative of the geological surveys of the world. Its aim is to create dynamic geological map data of the world available via the web. These pages provide a background to the initiative as well as up-to-date information on its progress.
