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.

Process_Step:

Process_Description:

The geologic map was digitized from 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.

Entity_and_Attribute_Information:

Overview_Description:

Entity_and_Attribute_Overview:

This dataset has both line (arc) entities and polygon attributes.

Polygon attibutes: P1: shorthand attribute NAME: name COUNT: number of polygons of each type (name) DETAIL: detailed description BW: Line pattern from CARTO.LIN (a linesymbol set in Arc/Info; for use in displaying the map in ArcPLOT) CCA: Line pattern from CCA.LIN or shade color from CCA.SHD; for use in displaying the map in ArcPlot DOT: Shade pattern from DOT.SHD (ArcPlot) PLT: Shade pattern from PLOTTER.SHD (ArcPlot) MINOR1: DLG3 optional style attribute MINOR2: DLG3 optional style attribute

In Arc Export file format, when the file is imported it also comes with an INFO file with a *.NAME extension, containing descriptions for the codes in the polygon attribute table.

In ArcView shapefile format, the shapefile is accompanied by a dbase file, name.dbf, containing descriptions for the the codes in the attribute table.
