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.

Geologic data that is measured at a specific location, or a feature that doesn't occupy enough space to be mapped as a line or polygon, is best represented as point data. Some point data, like fault and fold data, is topologically related to mapped features. Some point data, like fault slickenlines, is stored as a single record with the planar data that it is measured with.
