Spatial Digital Database for the Geologic Map of Nevada
Listed in NASA Earthdata CMR
This report publishes a geologic digital spatial database (nvgeo) representing the geologic map of Nevada (Stewart and Carlson, 1978a).
Description
The original paper map was printed as a single sheet at a scale of 1:500,000, then reprinted as two sheets in 1991. The database provided by this open-file report supercedes earlier published digital versions (Turner and Bawiec, 1991, Raines and others, 1996).
This digital spatial database is one of many being created by the U.S. Geological Survey as an ongoing effort to provide geologic information for use in spatial analysis in a geographic information system (GIS). This database can be queried in many ways to produce a variety of geologic maps. This database is not meant to be used or displayed at any scale larger than 1:500,000 (for example, 1:100,000).

The digital geologic map of Nevada consists of a single spatial database (nvgeo) which contains map units and lines. The feature attribute tables include a geologic linework table, NVGEO.AAT, that relates to the NVGEO.CON (contacts and boundaries), NVGEO.ST2 (structures), and NVGEO.REF (source reference) files, and a rock unit table, NVGEO.PAT, that relates to the NVGEO.RU (rock unit) and NVGEO.REF (source reference) files.
