Summary

The State Geologic Map Compilation (SGMC) geodatabase of the conterminous United States (https://doi.org/10.5066/F7WH2N65) represents a seamless, spatial database of 48 State geologic maps that range from 1:50,000 to 1:1,000,000 scale. 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 U.S. Geological Survey releases of the Preliminary Integrated Geologic Map Databases for the United States. The SGMC geodatabase also contains updated data for seven States and seven entirely new State geologic maps that have been [...]

Purpose

The purposes of these data are to provide a standardized, vector-based, state geologic map database of the conterminous U.S. at an approximate scale of 1:1,000,000. The compilation includes new geologic information and state maps, corrections to the original Preliminary Integrated Geologic Map Databases for the United States (PIGMD), and enhancements which are explained in the accompanying report. The data are suitable for use in Geographic Information Systems (GIS) or other database and geospatial software used to derive maps and perform geospatial analyses. The information is intended to meet the needs of a wide community of users that extends from geosciences to State and Federal agencies, private industry, and the general public.
