Description:

Abstract:: Geologic data from the geologic map of the Spokane 1:100,000-scale quadrangle compiled by Joseph (1990) were entered into a geographic information system (GIS) as part of a larger effort to create regional digital geology for the Pacific Northwest. The map area is located in eastern Washington and extendds across the state border into western Idaho.
Purpose:: To create a digital geologic map of the Spokane 1:100,000-scale quadrangle that is readily available to the public/

Process_Step:

Process_Description:: The original stable-base mylar of the geologic linework for the 1:100,000-scale geologic map was electronically scanned to create a raster digital image. The resulting TIFF-formate image (600 do per inch resolution) was registered to a UTM grid and rectified in Arc/Info. The rectified raster image was then converted to a vector GIS layer using the GRIDLINE vectorization tool included in the Arc/Info GRID extension. Subsequent clean-up of the vector layer was done in PC Arc/Info. Linework for water bodies that obscured geologic contact was converted from digital line graph (DLG) formate files to PC Arc/Info so as to delineate discrete geologic unit boundaries. The resulting geologic map was attributed, converted to Arc/Info, and then plotted and compared to the original mylar to check for digitizing and attributing errors.
