This pamphlet serves to introduce and describe the digital data. No paper map is included in the Open-File report, however this report includes a PostScript and a Portable Documet Format plot file containing an image of a geologic map sheet and an explanation. Purpose: To provide it provides basic information on the stratigraphy and structure of the area of the San Francisco South 7.5' quadrangle and the western part of the Hunters Point 7.5 quadrangle to the public.

Wentworth, Todd T. Fitzgibbon, and Geoffrey A. Phelps graciously provided assistance with Alacarte and ARC/INFO. The scanning of the whole 1:24,000 quad and initial editing of the quarters of the map after it was divided was done by the following individuals: Heather Schoonover (northwest), Marjorie Lucks (southeast), Scott Graham (southwest), and Carl Wentworth (northeast). Marjorie Lucks compiled the sub-quadrangles, skillfully made many changes requested by the author, and did much of the final editing of the whole map along with Thomas May. Native_Data_Set_Environment: ARC/INFO version 7.0.4 Data_Quality_Information: Logical_Consistency_Report: The geologic map information was digitized from stable originals of the geologic map at 1:20,000 scale. Completeness_Report: The map's small scale does not provide sufficient detail for site development purposes. In addition, this map does not take the place of fault-rupture hazard zones designated by the California State Geologist (Hart and Bryant, 1997). The map shows mappable landslides as they existed about 1959. Although many of the landslides still exist, many others have been removed during urban development or by natural processes, and post-1959 landslides are not shown.

A mylar copy of the earlier map (Bonilla 1965) was scanned using a Altek monochrome scanner with a resolution of 800 dots per inch. The scanned images were vectorized and transformed from scanner coordinates to projection coordinates with digital tics placed by hand at quadrangle corners. The scanned lines were edited interactively by hand using ALACARTE, color boundaries were tagged as appropriate, and scanning artifacts visible at 1:24,000 were corrected. Base Map layers were prepared from scale-stable printing negatives of the U.S. Geological Survey San Francisco South (1980 photorevision), and Hunters Point (1980 photorevision) 1:24,000 topographic maps, which have a 25 foot contour interval. These base map layers are digital images but no information other than location is attached to the lines. The base maps are provided for reference only.
