State Geologic Map Compilation – Geology

State Geologic Map Compilation – Geology This feature layer, utilizing data from the U.S. Geological Survey (USGS), portrays the State Geologic Map Compilation (SGMC) geodatabase of the conterminous United States. Per USGS, the SGMC "represents a seamless, spatial database of 48 State geologic maps. A national digital geologic map database is essential in interpreting other datasets that support numerous types of national-scale studies and assessments, such as those that provide geochemistry, remote sensing, or geophysical data. The SGMC is a compilation of the individual USGS releases of the Preliminary Integrated Geologic Map Databases for the United States."
