1. Abstract This geologic map was prepared as part of a study of digital methods and techniques as applied to complex geologic maps. The geologic map was digitized from the original scribe sheets used to prepare the published Geologic Map of Wyoming (Love and Christiansen, 1985). Consequently, the digital version is at 1:500,000 scale using the Lambert Conformal Conic map projection parameters of the State base map. Stable base contact prints of the scribe sheets were scanned on a Tektronix 4991 digital scanner. The scanner automatically converts the scanned image to an ASCII vector format. These vectors were transferred to a VAX minicomputer, where they were then loaded into ARC/INFO. Each vector and polygon was given attributes derived from the original 1985 geologic map. Descriptors: The Digital Geologic Map of Wyoming in ARC/INFO Format Open-File Report 94-0425 2. Applications that use this data models and assesments 2.1 Intended use of data base geologic map 2.2 Limitations of data Scale is 1:500,000 and should not be used outside that range WATER, ROADS, CONTOURS, AND TOWNS: Published geologic maps are prepared using a USGS topographic base map that contains the hydrology, hypsography, and political features. Because this digital version of the Geologic Map of Wyoming started with the original geologic scribe sheets, these features were not present. Only those water bodies that were required to close polygons were added by hand. The digital hydrology is not complete or as accurate as the original USGS 1:500,000 topographic base. A few water bodies were added for visual effect. No roads, contours, or towns were present on the geologic scribe sheets and none were added to this digital version. 3.

Revisions made to data (revision number, date, description) none 6. Reviews applied to data (review type, date, person, description) The database was reviewed at the University of Wyoming, Wyoming Water Resources Center. The review was cross-checked at the USGS in Denver. The authors wish to thank Dave Love and Ann Coe Christiansen for providing access to the original Geologic Map of Wyoming scribe sheets and negatives. For the digital review, we also thank Pat Stamile of the USGS and Chris Arneson and Laisan Serebryakov of the University of Wyoming Water Resources Center. 7.
