Geologic mapping and digital preparation of this report were sponsored jointly by (1) the National Cooperative Geologic Mapping Program of the U.S. Geological Survey, (2) the California Geological Survey, and (3) the Southern California Areal Mapping Project (SCAMP). The California Geological Survey graciously provided geologic map data and critical input.
These data sets were derived to describe the relative soil-slip susceptibility for upland areas of southwestern California. Although released on a 1:100,000-scale topographic base, the data were derived at a scale of 1:24,000 and as such can be transferred from 1:100,000-scale to 1:24,000-scale without any loss of accuracy. The maps are not intended to be used at any scale larger than 1:24,000.
Are there legal restrictions on access or use of the data?Access_Constraints: none
Use_Constraints:This data base is not to be used at a scale larger than 1:24,000.
