The files are in either GRID (ARC/INFO raster data) format or COVERAGE (ARC/INFO vector data) format. Coverages are stored in uncompressed ARC export format (ARC/INFO version 7.x). ARC/INFO export files (files with the .e00 extension) can be converted into ARC/INFO coverages in ARC/INFO (see below) and can be read by some other Geographic Information Systems, such as MapInfo via ArcLink and ESRI's ArcView (version 1.0 for Windows 3.1 to 3.11 is available for free from ESRI's web site: http://www.esri.com/ ). The digital compilation was done in version 7.0.4 of ARC/INFO with version 3.0 of the menu interface ALACARTE (Fitzgibbon and Wentworth, 1991, Fitzgibbon, 1991, Wentworth and Fitzgibbon, 1991). The PostScript plotfiles for maps were produced by the "postscript" command with compression set to zero in ARC/INFO version 7.0.4. The PostScript plotfiles for pamphlets were produced in Microsoft Word 6.0 using the Destination PostScript File option from the Print command.

End_Group End_Group Group: Reference End_Group Group: Summary This map is intended to be of general use to engineers and land-use planners. However, its 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, 1988). Similarly, the database cannot be used to identify or delineate landslides in the region. For a depiction of landslide distribution, see Brabb and Pampeyan (1972), Brabb and others (1978), Mark (1992), Wieczorek and others (1985), and Wieczorek and others (1988). This digital map database, compiled from previously published and unpublished data, and new mapping by the authors, represents the general distribution of bedrock and surficial deposits in San Mateo County. Together with the accompanying text, it provides current information on the geologic stucture and stratigraphy of the area covered. The database delineates map units that are identified by general age and lithology following the stratigraphic nomenclature of the U.S. Geological Survey. The scale of the source maps limits the spatial resolution (scale) of the database to 1:62,500 or smaller. Additional information is available in two textual reports: smgeo.ps is a PostScript report containing detailed unit descriptions and geological information, sources of data and cited references. The text is available in smgeo.txt. smdb.ps is a PostScript report describing the structure of the database. The text is available in smdb.txt. >ARC/INFO coverages >sm_um-py.e00 > Faults, depositional contacts, and rock units in San Mateo County >sm_um-sr.e00 > Strike and dip information and fold axes in San Mateo County >sm_quad.e00 > Index map of quadrangles in San Mateo County. >sm_um-flt.e00 > Index map of faults in San Mateo County with annotation showing the names of major faults. >sm_corr.e00 > Correlation table for the units in this map database. >sm_so.e00 > Sources of data index map for this map database. >sm_as.e00 > Index map of Assemblages in San Mateo County.
