NMBGMR Draft Geologic Data Model - v. 1.0.4

In the interests of standardization and interoperability, we are migrating our geologic maps into the USGS NCGMP09 data model. However, our well data model is still actively being used. Documentation for the NMBGMR geology data model is being provided for users with legacy data in this model. We also hope that it will provoke discussion in the ongoing effort to improve NCGMP09 and other models.

Areas with similar lithologic, geomorphic, metamorphic or other characteristics are defined by polygons. These polygons may have boundaries that have their own attributes and are topologically linked. For instance, polygons for lithologic units are bounded by geologic contacts that are attributed with various properties like class, type, exposure, confidence, etc.
