Southern California Areal Mapping Project

Project Description
SCAMP is a cooperative mapping project between the U.S. Geological
Survey and the California Division of Mines and Geology. The project
provides a variety of geologic-information products for public access
in southern California-including geologic and geophysical maps and
reports that describe the geologic setting and geologic history of
southern California. These maps and reports are providing a foundation
for specialized investigations of geologic hazards and earth
resources, and can be used for land-use planning decisions that
involve earth-science data.

The project has two objectives:

* Develop a uniform geologic-map data base for southwestern California
that will provide a geologic foundation for a broad range of societal
applications--including evaluations of geologic hazards, natural
resources, and environmental quality

* Determine the geologic framework and geologic history of
southwestern California, with emphasis on the evolution of the San
Andreas fault system.


These objectives are achieved mainly by making general-purpose
geologic maps in digital form. Studies of isotope geology and
geochronology, regional geophysics and geochemistry, paleontology,
geomorphology, and pedology provide essential information that is
incorporated into the map data base.

For the entire project area, the geologic-map data base will be at
1:100,000 scale; where warranted by geologic and societal issues,
additional maps will be produced at 1:24,000 and 1:48,000 scale. The
maps produced may include both surface-geology maps and
subsurface-geology maps generated from drill records and from
geophysical data. The maps are digitally produced using the Geographic
Information System (GIS) software ARC/INFO, and graphic files are
available for downloading in several formats via anonymous ftp. Future
plans include map release of digital geologic folios on CD-ROM. The
primary folio layer will be a digital geologic map, mostly captured at
1:100,000 scale.
