***** The Surficial Geology and Bedrock Geology of the Green River Basin coverages were simply clipped from the Wyoming Statewide coverages. The original metadata is preserved with the exception of noting the datum change from NAD83 to NAD27. ***** 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. The dataset has both polygon and line features (faults), with attributes derived from the 1985 map. Purpose: This geologic map was prepared as part of a study of digital methods and techniques as applied to complex geologic maps.

The data is stored in Arc/Info 7.0.4 software for Unix operating system. The data has been made available in Arc/Info export format (polygon and line features), and ArcView shapefile format (polygon only) Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The accuracy of the attributing is unknown Quantitative_Attribute_Accuracy_Assessment: Attribute_Accuracy_Value: unknown Attribute_Accuracy_Explanation: none Logical_Consistency_Report: Polygon topology present and Arc/Info reports matching labels/polygons Line toplogy also present. Completeness_Report: Unknown, but likely to be as complete in attributing as the Love and Christiansen geologic map. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The USGS does not have National Mapping Accuracy Standards for data produced at the 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.
