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.

This section illustrates how standard symbols for point, line, and polygon features map to attributes in the geologic data model. The intention here is to assist digitizers and mappers in understanding how a particular feature should be coded in the model. A subset of only the most commonly encountered map symbols is presented here. New symbols will be added as they are encountered.

See the NMBGMR Symbol set (3.7 Mb PDF) for details on how our standard symbology is constructed. Point, Line, or Polygon features (links above) within the data model will be symbolized using our standard symbol set. This section indicates how standard features portrayed on a geologic map should be coded in the data model. In general, symbology will be based on the FDGC Geologic Symbol Standard.
