GeMS DB v1pt1

A list of geologic maps distributed in the single-map USGS Geologic Map Schema (GeMS; formerly known as NCGMP09). Select legacy DGGS geologic maps in areas with critical mineral potential have been converted to the GeMS schema, benefiting DGGS and USGS critical mineral studies in Alaska. Future additions include both converted geologic maps, and new geologic maps created using the GeMS schema. Find out more about the GeMS enterprise database project.
