The USGS and its partners, the State Geological Surveys, have since the 1800s been producing high quality, standardized geologic maps of the Nation. Check out the National Geologic Map Database (NGMDB), which is charged with building a National archive of these maps and related geoscience reports.

The National Map is a collaborative effort among the USGS and other Federal, State, and local partners to improve and deliver topographic information for the Nation. It has many uses ranging from recreation to scientific analysis to emergency response. The National Map is easily accessible for display on the Web, as products and services, and as downloadable data.
