NMBGMR Draft Geologic Data Model - v. 1.0.3
SYMBOLOGY: Polygon Features

revised: 29-Feb-2012

This document indicates how geomorphic surfaces (not deposits) 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.

Description Symbol Feature Classes & Attributes Comment
pediment surface Surface_poly
  • SurfaceID=[variable]
  • Overlies=[variable]
  • SurfMod=[unspecified, dissected, undissected]
  • Confidence=[unspecified, variable]
 Erosional surface cut on bedrock related to erosion along a mountain front. Symbolized based on join to Sufaces table.
Geomorphic-Surface Surface_poly
  • SurfaceID=[variable]
  • Overlies=[variable]
  • SurfMod=[unspecified, dissected, undissected]
  • Confidence=[unspecified, variable]
 General geomorphic surface, may either be a strath or the aggredational top of a deposit. Symbolized based on join to Sufaces table.
