Together with the accompanying pamphlet, it provides current information on the geologic structure 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 1:100,000 or smaller. Purpose: This database and accompanying plot files depict the distribution of geologic materials and structures at a regional (1:100,000) scale. The report is intended to provide geologic information for the regional study of materials properties, earthquake shaking, landslide potential, mineral hazards, mineral and energy resources, seismic velocity, and earthquake faults. In addition, the report contains new information and interpretations about the regional geologic history and framework. However, the regional scale of this report 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. Similarly, the database cannot be substituted for comprehensive maps that systematically identify and classify landslide hazards. Supplemental_Information: The databases in this report were compiled in ARC/INFO, a commercial Geographic Information System (Environmental Systems Research Institute, Redlands, California). The files are COVERAGE (ARC/INFO vector data) format. Coverages are stored in uncompressed ARC export format (ARC/INFO version 8.1.2). 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. The geologic map information was digitized from stable originals of the geologic map at 1:100,000 scale. The author manuscripts (pen on mylar) were scanned. 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, color boundaries were tagged as appropriate, and some scanning artifacts visible at 1:100,000 were removed. This report has undergone two scientific peer reviews, a digital database review, and review of the plotfiles for conformity with USGS map standards. This report consists of a set of geologic map database files (Arc/Info coverages) and supporting text and plotfiles. The base map layer used in the preparation of the geologic map plotfiles was derived from a Digital Raster Graphic (DRG) of the Blythe 30' by 60' quadrangle (scale 1:100,000) produced by the U.S. Geological Survey. The base map has a 50 meter contour interval.

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 1:100,000 means that higher resolution information is not present in the dataset. Plotting at scales larger than 1:100,000 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.

Geologic information only mappable at larger scale has been omitted. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Well-located data items are intended to have a horizontal positional accuracy within .5 mm at 1:100,000 scale, or within 50 meters on the ground. The general positional accuracy of each line in the database is indicated within the LTYPE field in the Arc Attribute Table (see below). Points in the database are generally considered well located. The position of each data item is derived from the USGS topographic base map, and therefore additional inaccuracies arising from inaccuracies in the base map may be encountered.

Enumerated_Domain_Value_Definition_Source: author Overview_Description: Entity_and_Attribute_Overview: The databases in this report were compiled in ARC/INFO, a commercial Geographic Information System (Environmental Systems Research Institute, Redlands, California). Almost all the attributes in the various attribute tables of the coverages included in the report are set or calculated by Arc/Info. The exceptions are "coveragename"-ID, LTYPE, PTYPE, PTTYPE, STRIKE, and DIP. "coveragename"-ID is required by internal policy to be sequential. This ensures the highest compatibility of our databases with other GISs. Therefore "coveragename"-ID is calculated equal to "coveragename"#, which is a unique, sequential integer assigned by Arc/Info to each data record. LTYPE, PTYPE, and PTTYPE are author added items to the coverage AAT or PAT that are used to describe the type of line (LTYPE), area (PTYPE), or point (PTTYPE) being recorded. All coverages with AAT and PAT present include these items in the data structure. Each has WIDTH 35, OUTPUT 35, TYPE C. STRIKE and DIP are author added items to the coverage PAT that record information about the orientation of planar geologic structures. Both have WIDTH 3, OUTPUT 3, TYPE I. These items are recorded in the tables BLW-STR.PAT of the structure coverage. The base map layers are included for visual reference only and contain no data attributes or attribute tables.
