Description:

Abstract:

This digital map database is compiled from new mapping by the author, represents the general distribution of surficial and bedrock geology in the mapped area. Together with the accompanying pamphlet, it provides current information on the surficial geology and stratigraphy of the area. The database delineate map units that are identified by age and lithology following the stratigraphic nomenclature of the U.S. Geological Survey. The scale of the source maps limits the spatial resolution of the database to 1:12,000 or smaller.

Purpose:

This geologic map is part of a cooperative project between the U.S. Geological Survey and Northern Arizona University. The map area includes lower Comb Wash in southeastern Utah on the Colorado Plateau. This part of the Colorado Plateau was not previously mapped in adequate geologic detail. The geologic information in this report may be useful to land management, range management, and flood control programs for all federal and state agencies, and private affairs.

Supplemental_Information:

This report consists of a set of geologic map database files (ARC/INFO coverages) and supporting text and plot files. In addition, the report includes two sets of plot files (Post Script and PDF format) that will generate map sheets and pamphlets similar to a traditional USGS Open-File Report. These files are described in the explanatory pamphlets (cw_readme.txt, cw_readme.pdf, or cw_readme.doc).

Access_Constraints: None
Use_Constraints:

Uses of this digital geologic map should not violate the spatial resolution of the map area (1:12,000) even though the digital data form removes the constraint of scale on a paper map. The accuracy inherent in map scale are also present in digital format. At a scale larger than 1:12,000, higher resolution data is not available and will not yield greater real detail.

Process_Step:

Process_Description:

The databases in this report were compiled in ARC/INFO version 7.1.2, a commercial Geographic Information System (Environmental Systems Research Institute, Redlands, CA). The files are in vector (coverage) format. Coverages are stored in uncompressed ARC export format. ARC/INFO export files with the .e00 extension can be converted into ARC/INFO coverages in ARC/INFO and can be read by other commercially available Geographic Information Systems. Stable-base maps were digitized at the USGS Flagstaff Field Center using an Altek Datatab Proline AC32 digitizer. A tic file was created in latitude and longitude and projected into the base map projection (Transverse Mercator) using a central meridian of -112.375. Tics are defined in the four extreme corners of the map are in the geologic coverages corresponding with quadrangle corners both in base maps and digital maps. The tic file was used to transform the digitized coverage into Universal Transverse Mercator projection. ARC/INFO generated an RMS (root mean square) report after transforming the original coverage from digitizer units into real world coordinates. Digitized lines were edited interactively by hand using the ARC module ARCEDIT and a series of macros and menus, polygon regions were attributed as necessary, and all artifacts visible at 1:12,000 were removed.

Overview_Description:

Entity_and_Attribute_Overview:

The databases described in this report were compiled in ARC/INFO, a commercial Geographic Information System by Environmental Systems Research Institute. 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 being <COVER>-ID, LTYPE and PTYPE. LTYPE and PTYPE are author added aspects of the coverages added to the PAT or AAT and are used to describe the type of line( LTYPE), area (PTYPE), or point. LTYPE is defined with WIDTH 35, OUTPUT 35, and TYPE C (character). PTYPE is defined with WIDTH 6, OUTPUT 6, and TYPE C. Coverage cwn_profile contains only points. There are no defined attributes for these coverages.
