Description:

Abstract:

This Open-File report is a digital geologic map database of the Alameda County, California.

Purpose:

The data are released in a preliminary digital form to provide an opportunity for regional planners, local, state, and federal agencies, teachers, consultants, and others interested in geologic data to have the new data long before a traditional paper map is published.

Status:

Progress: Complete
Maintenance_and_Update_Frequency:

The authors currently plan to produce a second version of the geologic map of Alameda County that would include subdivided Quaternary units and enhanced stratigraphic description and nomenclature, both as a digital product and as a traditional paper map. The timing of release of these products, and indeed whether they will be produced at all, depends on a variety of factors, including funding, outside author control.

Data_Set_Credit:

We are grateful to Kristin R. McDougall, William V. Sliter, David Bukry, John A. Barron, and William P. Elder of the U.S. Geological Survey for the paleontologic determinations necessary to help establish the ages of rocks in Alameda County. Scott D. Hill, Superintendent of Watershed, kindly provided access to lands owned by the East Bay Regional Park District. Leo T. Bauer, Alameda Division Manager, provided access to lands owned by the San Francisco Water Department. G. Doug Myron, U.S. Geological Survey, arranged for access to some of the private land in the study area. Carl M. Wentworth, Todd T. Fitzgibbon, and Geoffrey A. Phelps graciously provided assistance with Alacarte and ARC/INFO. James J. Lienkaemper shared some of his knowledge of the creeping strand of the Hayward fault, and David. H. Oppenheimer provided maps showing the location of epicenters. Larry J. Dickerson and John M. Parker, U.S. Geological Survey volunteers, provided extensive support in the field. We are grateful to AmeriCorps for sponsoring Dickerson, Parker, and Brabb.

Data_Quality_Information:

Logical_Consistency_Report:

This digital map database, compiled from previously open-filed U.S. Geological Survey reports (Graymer and others, 1994), other published and unpublished data (see Sources of Data in algeo.txt), and substantial new mapping by the authors in about two- thirds of the county, represents the general distribution of rocks and geologic structures in Alameda County.

Completeness_Report:

Provides only current information on the stratigraphy and structural geology of the area covered.

Process_Step:

Process_Description:

The geologic map information was digitized from stable originals of the geologic maps at 1:24,000 scale for newly mapped areas and 1:62,500 scale for the rest of the county. The author manuscripts (ink on mylar) were scanned using a Tektronix 4991 monochrome scanner with a resolution of 304.8 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 a contact or fault as appropriate, and scanning artifacts visible at 1:50,000 were removed.
Base Map layers were prepared from scale-stable printing negatives of the U.S. Geological Survey San Francisco (1978 edition), Stockton (1989 edition), and San Jose (1978 edition) 1:100,000 topographic maps, which have a 50 meter contour interval. Scanned and vectorized images were transformed from scanner coordinates to projection coordinates with digital tics placed by hand at map corners. The images were then trimmed interactively by hand using ALACARTE to conform to the area of the geologic coverages, and the four portions were combined. Small mismatches at the boundaries caused by slight differences in the original scans remain in the three base map coverages. These base map layers are digital images but no information other than location is attached to the lines.
