NMBGMR Draft Geologic Data Model - v. 1.0.4
SYMBOLOGY: Linear Features - Section Lines

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 document indicates how cross section lines and other linear transects portrayed on a geologic map should be coded in the data model. See the NMBGMR Symbol set (3.7 Mb PDF) for details on how our standard symbology is constructed.
