Identification_Information: Citation: Citation_Information: Originator: U.S. Geological Survey Publication_Date: 1994 Title: Bedrock Geology of Wyoming Publication_Information: Publication_Place: Denver, CO Publisher: U.S. Geological Survey Online_Linkage: geology Description: Abstract: The geologic map was digitized from original scribe sheets used to prepare the published Geologic Map of Wyoming (Love and Christiansen, 1985), consequently at a 1:500,000 scale. Stable base contact prints of  the scribe sheets were scannned 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 loaded into Arc/Info. The dataset includes both linear and polygon features, with attributes derived from the original 1985 map. Purpose: This geologic map was prepared as part of a study of digital methods and techniques as applied to complex geologic maps.
