The 'Digital Geologic Map of Arizona; a digital database from the 1983 printing of the Eldred D. Wilson and Richard T. Moore, and John R. Cooper 1:500,000-scale map' Open-File Report 00-409 contains a detailed description of each attribute code and a reference to the associated map symbols on the map source materials. This GIS database consists of four Arc/Info datasets: one line and polygon file, azgeol, containing geologic contacts and structures (lines) and geologic map rock units (polygons), one line file, azfold, containing the folds and crater boundaries, one point file, azptfeat, containing geologic features, cinder cones and diatremes, and one point file, azptdec, containing decorations. Azgeol contains an arc attribute table, azgeol.aat, which relates geologic linework arc attribution to the contact look-up table, azgeol.con, the structural attribute table, azgeol.str and the source reference look-up table, sources.ref. Azgeol also contains a polygon attribute table, azgeol.pat, which relates the polygons to the rock-unit look-up table, azgeol.ru, and the source reference look-up table, sources.ref. Azfold contains an arc attribute table, azfold.aat, which relates to the structural attribute table, azfold.str, and the source reference look-up table, sources.ref. Azptfeat contains the point attribute table, azptfeat.pat, which relates the feature points to their descriptions in azptfeat.lut, and the source reference look-up table, sources.ref. Azptdec contains the point attribute table, azptdec.pat, which relates the points to descriptions in the look-up table, azptdec.lut, and the source reference look-up table, sources.ref.
