Although the digital form of the data removes the constraint imposed by the scale of a paper map, the detail and accuracy inherent in map scale are also present in the digital data. The fact that this database was edited for a scale of 1:24,000 means that higher resolution information is not present in the dataset. Plotting at scales larger than 1:24,000 will not yield greater real detail, although it may reveal fine-scale irregularities below the intended resolution of the database. Similarly, where this database is used in combination with other data of higher resolution, the resolution of the combined output will be limited by the lower resolution of these data. Originating_Center: (required) Group: Data_Center Data_Center_Name: U.S. Geological Survey Dataset_ID: USGS Open-File Report OF-00-127 consists of both traditional geologic map products and Arc/Info format geospatial databases. Furthermore, the traditional geologic map products (map sheets and pamphlets) can be obtained either as paper or as digital plot files.

End_Group Group: Reference End_Group Group: Summary These susceptibility maps and the cost assessment data allow landowners in rural western San Mateo County to determine if their property is impacted by deep-seated landslide and debris flow hazards and, if so, how much money might be required to investigate them. The information is also useful for land use planners, local officials and public interest groups. For example, the maps will be useful for purposes such as determining where sediment from landslides might adversely affect fish in the various creeks, or where roads might be closed after heavy rainfall. This publication addresses deep-seated landslide susceptibility, debris flow susceptibility, and other geologic hazards in rural parts of western San Mateo County. The report also estimates possible costs of investigating and mitigating the landslide hazards. The study area includes the Half Moon Bay 7.5' quadrangle, the Montara Mountain 7.5' quadrangle, and the Pescadero/Butano Creeks watershed. Hazard maps were derived by integrating slope data and previous geologic, landslide and debris flow mapping. The digital database, which is found at http://geopubs.wr.usgs.gov/open-file/of00-127 includes 43 plotfiles for slope maps, Digital Orthophoto Quadrangle maps, Digital Raster Graphic topographic base maps, geologic maps, deep-seated landslide inventory maps, deep-seated landslide susceptibility maps, and debris flow inventory and susceptibility maps. Twelve ARC export files of supporting digital data are included in the database, and other data have been published previously and are available at other USGS websites named in an accompanying pamphlet (of00-127_2. ps, of00-127_2.pdf, of00-127_2.txt). All data layers are in Universal Transverse Mercator (UTM) projection, zone 10. The scale of the source maps limits the spatial resolution (scale) of the database to 1:24,000. An explanatory pamphlet (of00-127_2.ps, of00-127_2.pdf, of00-127_2.txt) accompanies the digital database.
