NMBGMR Draft Geologic Data Model - v. 1.0.4
LINES: Cross Sections & Transects

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 feature class records the locations of cross section lines, seismic/gravity profiles, or other transects. Geologic cross sections are stored as a separate Feature Datasets with a names like Xsect_AA, Xsect_BB, etc.
