The structure of this geodatabase and its associated feature classes, as well as the feature class naming conventions, loosely follows The National Park Service Geologic Resources Inventory GIS Geodatabase Data Model v.2.1, which can be found at: http://science.nature.nps.gov/im/inventory/geology/GeologyGISDataModel.cfm. This geodatabase includes the following: Feature classes: bedding, foliation, and fault attitudes (provatd), fold axes (provfld), geologic contacts and faults (provglg_arc), concealed geologic faults (provglg_conc_flt), geologic unit polygons (provglg_poly), geologic unit points (provglg_pt), tuff localities (provgpt), cross section lines (provsec), and cartographic symbols (prov_carto). Annotation feature classes: miscellaneous (provmisc_anno), attitude and fault (provatd_anno), and geologic units (provglg_anno). Relationship class: provatdpt_anno - links provatd to provatd_anno. Note: This geodatabase and its metadata were originally created in ArcGIS 9.3. Metadata in this report is current. The FGDC read-only metadata appended to the end of this report is no longer fully accurate and cannot be deleted. Purpose: This digital database depicts distribution of geologic materials and structural features at 1:24,000-scale. The publication, which also includes an explanatory pamphlet, 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 pamphlet contains new information and interpretations about regional geologic history and framework. However, the 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 classifay landslide hazards.

Technical review was provided by Keith Howard and Kevin Schmidt of the U.S. Geological Survey. Digital review was provided by Michelle Roberts of the U.S. Geological Survey. Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Geologic features in this geodatabase were symbolized based on attributes, plotted at 1:24,000-scale and visually reviewed for accuracy by the authors. Logical_Consistency_Report: This geodatabase has been reviewed and is considered to be error-free. All features have attributes. Each line segment has a length and directionality that is appropriate for the geologic feature it depicts. No sliver polygons are present. Geologic lines (provglg_arc) and geologic units (provglg_poly) are topologically related entities. The following topology rules were employed to maintain the topological integrity of the data: geologic lines 1) must not self-overlap, 2) must not self-intersect, 3) must not have pseudonodes, 4) must not intersect or touch interior, 5) must be single part, and 6) must not have dangles [excepting faults]; geologic unit polygons 1) must not overlap, 2) must not have gaps, and 3) boundary must be covered by provglg_arc. Completeness_Report: This geodatabase is considered complete. All geologic features on the source maps were digitized and attributed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Most of the geologic features in this database are considered to be accurately located and within +/- meters of their actual location on the 24,000-scale topographic base. Many features were located in the field using a hand-held GPS (Global Positioning System) device. The 24,000-scale topographic maps and corresponding Digital Raster Graphics (DRGs) used as the primary mapping bases for this project were assumed to meet the National Map Accuracy Standard of +/- 12 meters. The scanned source maps, which were georeferenced to the DRGs all had registration errors less than +/- 12 meters, and most had errors less than +/- 5 meters. Note: Refer to metadata for each feature class for detailed information about the positional accuracy of features. Lineage: Process_Step: Process_Description: Mapping was accomplished using a combination of field investigations and aerial photographs. New and existing geologic data were compiled on a 1:24,000-scale Mylar topographic base map which was scanned and saved in TIF format. The TIF files were georeferenced in ArcMap to corresponding 1:24,000-scale DRGs, using a 1st-order polynomial transformation and then used as a guide from which to heads-up digitize geologic data. Process_Step: Process_Description: Minor edits were made to the geodatabase to correct geology. The database was also upgraded from ArcGIS 9.3 to 10.2.
