Digitize an Analog Map With GeMS, Part B1

Digitize an Analog Map With GeMS, Part B1 - How to create an empty GeMS geodatabase in ArcMap, digitize contacts from a scanned geologic map, and create map unit polygons.

The Geologic Map Schema (GeMS) defines a standard database schema — a database design — for digital publication of geologic maps. This tutorial is one of six originally presented as part of a short course at the 2021 Northeastern Section Meeting of the Geological Society of America by Ralph Haugerud, USGS, on how to use ArcMap and custom tools to create GeMS-compliant ArcGIS file geodatabases.
