Data were compared to referenced data sources to ensure consistency. Data were fitted to national-scale state boundaries. Topologic rules were used to eliminate polygonal gaps or overlaps.
The data set is considered complete for the information presented and as described in the abstract. Users are advised to read the accompanying report and this metadata document carefully for additional details.

Newly updated data for California (geology, structure and points).
Process_Step:
Process_Description:
The 48 separate databases forming the Preliminary Integrated Geologic Map Databases for the United States (PIGMD) were integrated into a single ArcGIS 10 file geodatabase. Outdated state maps were replaced with newer state geologic maps or geologic information where available. All data were compared to published state geologic maps to ensure spatial integrity and data were fitted to a USGS national-scale state boundary. Attributes in the original state geologic map databases were standardized to conform to the USGS SGMC format (see the accompanying data series report for details). Errors, primarily in the coding of attributes, were corrected when reported or encountered. Where appropriate, supporting tables were updated to reflect current USGS nomenclature and linkages between tables were checked.
Process_Date: 2016
Process_Step:
Process_Description:
Version 1.1: California - replaced the original digital data (Saucedo, George J., Bedford, David R., Raines, Gary L., Miller, Robert J., and Wentworth, Carl M., GIS Data for the Geologic Map of California, California Geological Survey, CD 2000-07) with the newer version (Jennings, C.W., with modifications by Gutierrez, C., Bryant, W., Saucedo, G., and Wills, C., 2010, Geologic map of California, Version 2.0 (California Geological Survey 150th Anniversary Edition), Department of Conservation, California Geological Survey: California Geologic Data Map Series, GDM No. 2, scale 1:750,000.).
The newer 2010 California data contains corrections of spatial errors of up to 1km in the older dataset and updated fault, and point features. See the original source metadata of California for more information.
