Purpose: This data set was developed as part of the Arizona Geological Survey's ongoing efforts to provide geologic information in a digital format. The data can be used for analytical statistical purposes, planning and land management as well as for producing cartographic maps. Supplemental_Information: The Geologic data for this series is contained in a geodatabase. See accompanying text "DMT04_NGMDB database structure.pdf" for further information.

Registration is explained in 2.4.1.1 (Horizontal Position Accuracy Report). The map was digitized using PC Arc/Info 3.4.2 and a Calcomp Drawingboard II table digitizer. Arcs were digitized in the Arcedit module using stream mode with the weed tolerance set at 5.08 meters. All arcs were later smoothed with the Arcedit spline command with the grain tolerance set at 40 meters. Any processing of the coverages using the Arc clean command had dangle and fuzzy tolerances of 2 meters. Transparencies of the digitized arcs were overlayed with the original, mylar source maps for proofing. After the linework was completed and proofed, the geology and lines coverages were generalized with a 5 meter weed tolerance to reduce the number of vertices in the straighter arcs.
