| This report describes and makes available a geologic digital spatial database (nvgeo) representing the geologic map of Nevada (Stewart and Carlson, 1978a). 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 supersedes 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).
This report also describes the methods used to convert the geologic map data into a digital format, describes the ArcInfo GIS file structures and relationships, and explains how to download the digital files from the U.S. Geological Survey public access World Wide Web site on the Internet. Scanned images of the 1991 reprinting of the Stewart and Carlson (1978a) map are also available for download. |
