Publication_Date: 2007 Publication_Time: Title: Geologic map and map database of eastern Sonoma and western Napa Counties, California Edition: 1.0 Geospatial_Data_Presentation_Form: geologic map Series_Name: U.S. Geological Survey Scientific Investigations Map Issue_Identification: 2956 Publication_Information: Publication_Place: Menlo Park, CA Publisher: U.S. Geological Survey Other_Citation_Details: Online_Linkage: http://pubs.usgs.gov/sim/2007/2956 Description: Abstract: This digital map database, compiled from previously published and unpublished data, and new mapping by the authors, represents the general distribution of bedrock and surficial deposits in the mapped area. Together with the accompanying text file (eswnmf.ps, eswnmf.pdf, eswnmf.txt), 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 1:62,500 or smaller. Purpose: This database and accompanying plot files depict the distribution of geologic materials and structures at a regional (1:62,500) scale. The report is intended to provide geologic information for the regional study of materials properties, earthquake shaking, landslide potential, mineral hazards, 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 (Hart and Bryant, 1999). Similarly, the database cannot be used to identify or delineate landslides in the region. Supplemental_Information: Procedures_Used: The databases in this report were compiled in ARC/INFO, a commercial Geographic Information System (Environmental Systems Research Institute, Redlands, California), with version 3.0 of the menu interface ALACARTE (Fitzgibbon and Wentworth, 1991, Fitzgibbon, 1991, Wentworth and Fitzgibbon, 1991). 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). 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 7.1.1 of ARC/INFO with version 3.0 of the menu interface ALACARTE (Fitzgibbon and Wentworth, 1991, Fitzgibbon, 1991, Wentworth and Fitzgibbon, 1991). The geologic map information was digitized from stable originals of the geologic maps at 1:62,500 and 1:24,000 scale. The author manuscripts (pen on mylar) were scanned using a Altek monochrome scanner with a resolution of 800 dots per inch. 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 using ALACARTE, color boundaries were tagged as appropriate, and scanning artifacts visible at 1:24,000 were removed. Revisions: 03/12/2007 There have been no revisions to any part of the report. Please see the ASCII text file sim2956.rev for more information about revisions. Reviews_Applied_to_Data: This report has undergone two scientific peer reviews, one digital database review, one review for conformity with geologic names policy, and review of the plotfiles for conformity with USGS map standards. Related_Spatial_and_Tabular_Data_Sets: This report consists of a set of geologic map database files (Arc/Info coverages) and supporting text and plotfiles. In addition, the report includes two sets of plotfiles (PostScript and PDF format) that will generate map sheets and pamphlets similar to a traditional USGS Miscellaneous Field Studies Report. These files are described in the explanatory pamphlets (eswnsim.ps, eswnsim.pdf, or eswnsim.txt). The base map layer used in the preparation of the geologic map plotfiles was derived from scanned and vectorized versions of USGS 1:125,000 scale regional topographic maps (Aitken, 1997).

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 1:62,500 means that higher resolution information is not present in the dataset. Plotting at scales larger than 1:62,500 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.

Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: See Entity_Attribute_Information Quantitative_Attribute_Accuracy_Assessment: Attribute_Accuracy_Value: See Explanation Attribute_Accuracy_Explanation: Attribute accuracy is described, where present, with each attribute defined in the Entity and Attribute Section. Logical_Consistency_Report: Polygon and chain-node topology present Completeness_Report: The report is intended to describe completely the surficial deposits and bedrock geology at 1:62,500 scale. Geologic information only mappable at larger scale has been omitted. In addition, landslide deposits are for the most part not recorded. 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 1:62,500 scale, or within 31 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 to be 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 also be encountered. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: No vertical positional data recorded. Lineage: See Supplemental_Information Process_Step: Process_Description: Geologic linework was scanned, converted to vector data, and edited on-screen to repair errors visible at map scale. Polygon topology was created and each polygon tagged on-screen. Structural information was digitized by hand using a digitizing table. Plotfiles were created in ArcPlot.

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, FAULTNAME, 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 only recorded in the table ESWN-STRC.PAT. FAULTNAME is an author added item the coverage AAT that records information about the names of faults in the map area.
