Data

This digital database was originally compiled in ArcInfo coverage format with ArcInfo version 7.2.1. The database was upgraded for this release to ArcGIS 9.3.1 personal geodatabase format and consists of feature datasets containing geologic map feature classes for each of the three printed map plates (see PLOTFILES section) from U.S. Geological Survey Professional Paper 729-G. ArcGIS-compatible GIS software is therefore required to use the files of this database. The geodatabase is stored in a single zipped folder (PP729-G.zip) in this release for ease of transfer. The scale of the source maps limits the spatial resolution (scale) of the database to 1:125,000 or smaller for Plates 1 and 2, and 1:500,000 or smaller for Plate 3. Available ArcGIS feature classes, organized by Plate 1, 2, and 3 feature datasets are described below:
