Publication_Date: 2003 Title: Geologic Map and Digital Database of the Lower Grand Wash Cliffs and Vicinity, Mohave County, Northwestern Arizona Edition: Version 1.0 Geospatial_Data_Presentation_Form: geologic map Series_Information: Series_Name: U.S. Geological Survey Miscellaneous Field Studies Report Issue_Identification: Map MF-2427 Publication_Information: Publication_Place: Flagstaff, AZ Publisher: U.S. Geological Survey Online_Linkage: http://pubs.usgs.gov/mf/2004/2427 Description: Abstract: This digital map database is compiled from unpublished data and new mapping by the authors and represents the general distribution of surficial and bedrock geology in the mapped area. Together with the accompanying pamphlet, it provides current information on the geologic structure and stratigraphy of the area. The database dilineates 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 the Lower Grand Wash Cliffs and vicinity is mostly in the Grand Wash trough of the Basin and Range province and partly in the Grand Wash Cliffs and Grand Gulch Bench of the Colorado Plateau Province, all in northwestern Arizona. This 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 Grand Canyon National Park, Lake Mead National Recreation Area, and Grand Canyon-Parashant National Monument. This map fills one of the remaining areas where uniform quality geologic mapping is needed. The geologic information presented will be useful for resource management studies for federal, state, and provate agencies. Supplemental Information: This digital publication contains all the information used to publish U.S. Geological Survey Miscellaneous Field Studies Report MF-2427. The scale of the source map limits the spatial resolution (scale) of the database to 1:31,680 or smaller. The content and character of the digital database, as well as methods for obtaining the digital files, are described here. This metadata document contains information for the entire set of ArcInfo coverages included in this database. The following four coverages are documented here: gw_poly, gw_dip, gw_fold, and gw_anno. The coverages and their associated INFO directories have been converted into ARC/INFO export files. ARC export files are converted to ARC/INFO format using the ARC 'import' command. To ease conversion and preserve naming convention, an AML is enclosed that will convert all the export files in the database to coverages and will also create an associated INFO directory. From the ARC command line type '&r import.aml'.

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. Where this database is used in combination with other data of higher resoultion, the resolution of the combined output will be limited by the lower resolution of these data. Acknowledgement of the U.S. Geological Survey would be appreciated in products derived from these data. 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.

Logical_Consistency_Report: Polygon and chain-node topology present. Polygons internal to the map boundary are completely enclosed by line segments which are themselves a set of sequentially numbered coordinate pairs. Point data are represented by coordinate pairs. The neatline was mathematically generated from latitude and longitude values. Completeness_Report: The geolgic map and digital database of the Lower Grand Wash Cliffs 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 0.5 mm at a 1:31,680 map scale, or 16 meters on the ground. Lineage: Process_Step: Procsses_Description: Stable-base maps were scanned at the Flagstaff USGS Field Center on 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 latitute and longitude and projected into the base map projection (Polyconic) using a central meridian of -114.0000. Tics are defined in the four extreme corners of the map and correspond with quadrangle corners. The tic file was used to transform the grid into Universal Transverse Mercator projection. ARC/INFO generated a root mean square (RMS) report after transforming the original Grid 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 1:31,680 were removed.

Geospatial entities in ARC/INFO coverages have the following software-defined attributes: .pat contains AREA, PERIMETER, #, and -ID; .aat contains FNODE#, TNODE#, LPOLY#, RPOLY#, LENGTH, #, and -ID. User-defined attributes are described in detail below. (1) The coverage gw_poly includes the following feature attribute tables: (a) a polygon feature attribute table (GW_POLY.PAT) that describes the geospatial distribution of surficial units represented in the Postscript (.eps) and Portable Document Format (.pdf) plotfiles of the map. GW_POLY contains a PATTERN attributes desfining unit fill patterns. (b) an arc feature attribute table (GW_POLY.AAT) that describes the contacts and linear features that bound rock-unit polygons. For display purposes, the GW_POLY coverage includes an annotation class which contains line types and arcmarker symbols derived from the coded items LTYPE and PTTYPE respectively. (2) The coverage gw_fold includes an arc feature attribute table (GW_FOLD.AAT) that describes linear features (folds and basalt flow lines). For display purposes, the GW_FOLD coverage includes an annotation class which contains line types and arcmarker symbols derived from the coded items LTYPE and PTTYPE respectively. Arrowheads indicating plunging folds are drawn based on values in the coded item PLUNGE. (3) The coverage GW_DIP includes the following: (a) a point feature attribute table (GW_DIP.PAT) that describes the position of point data including strike and dips, collapse features, sinkholes, and volcanic vents. Symbols are derived from the item PTTYPE, dip angle in degrees is derived from item DIP, and strike angle in degrees is from item STRIKE. (b) GW_DIP also contains annotation for fault offsets, and dip values. (4) The coverage GW_ANNO, containing subclass anno.unit, is used to annotate geologic unit labels. The unit labels were derived from the coded item PTYPE in the coverage cwpoly.
