Together with the accompanying pamphlet, it provides current information on the geologic structure and stratigraphy of the area. The database delineates 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 1:31,680 or smaller. Purpose: The geologic map of Hidden Hills and vicinity covers part of the Arizona Strip north of Grand Canyon and several large tributary canyons that make up the western part of Arizona's Grand Canyon. The map is part of a cooperative U.S. Geological Survey, National Park Service, and Bureau of Land Management project to provide geologic information for areas within the newly established Grand Canyon-Parashant National Monument. This map fills in one of the remaining areas where uniform quality geologic mapping was needed. The geologic information will be useful for future resource management studies for federal, state, and private agencies.

The accuracy inherent in map scale is also present in digital format. At a scale larger than 1:31,680, higher resolution data is not available and will not yield greater real detail. Any hardcopies utilizing these datasets shall clearly indicate their source. If users modify the data in any way they are obligated to describe the types of modifications they have performed. User specifically agrees not to misrepresent these datasets, nor to imply that changes they made were approved by the U.S. Geological Survey.

Native_Data_Set_Environment: Windows 2000 ARC/INFO version 8.0.2 Illustrator 8.0 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: 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. Logical_Consistency_Report: Polygon and chain-node topology present. Completeness_Report: This report is designed to describe completely the surficial and bedrock geology at a 1:31,680 scale. Geologic information only mappable at a larger scale has been omitted. All geospatial database elements are attributed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Well-located data are intended to have a positional accuracy within .5 mm at a 1:24,000 map scale, or 12 meters on the ground. Lineage: 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 either raster (GRID) or 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 scanned at the Flagstaff USGS Field site using an Optronics 5040 raster scanner at a resolution of 50 microns (508 dpi). The resulting raster file was in RLE format and converted to the RLC format using the "rle2rlc" program written by Marilyn Flynn. The RLC file was subsequently converted to an ARC/INFO Grid in ARC/INFO. The linework was vectorized using Gridline. 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 grid into Universal Transverse Mercator projection. ARC/INFO generated an RMS (root mean square) report after transforming the original Grid (raster image) into UTM. Scanned 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 and scanning errors visible at 1:24,000 were removed.

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 -ID, LTYPE, PTYPE, PTTYPE, PATTERN, STRIKE, and DIP. LTYPE, PTYPE and PTTYPE 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), point or arcmarker (PTTYPE). LTYPE and PTTYPE are each defined with WIDTH 35, OUTPUT 35, and TYPE C (character). PTYPE is defined with WIDTH 5, OUTPUT 5, and TYPE C. STRIKE and DIP are only present in HH_DIP.PAT, because they describe bedding orientation of point objects. Each is defined with WIDTH and OUTPUT of 3, and TYPE I (integer). PATTERN was another author-added attribute only in HR_POLY.PAT, and is defined by WIDTH 3, OUTPUT 3, and TYPE I. One coverage not described is HH_ANNO. This coverage contains only annotations, and leader placement. There are no defined attributes for this coverage.
