Abstract:
A paper copy of the Geologic Map of the Catalina Core Complex and San Pedro Trough (Dickinson, 1992) was scanned and digitized by U.S. Geological Survey staff and contractors at the Southwest Field Office (Tucson, AZ) in 2000-2001 for input into an ArcInfo geographic information system (GIS). The resulting geologic map database (in ArcInfo format) can be queried in many ways to produce a variety of geologic maps. Digital base map data files. (topography, roadways, towns, and hydrography) are not included: they may be obtained from a variety of commercial and government sources. Geologic map graphics and plot files that are provided in the Open-File Report are representations of the digital database and are not designed to be cartographic products.
Purpose:
This database was constructed to provide a geologic map GIS for use in spatial analysis by a variety of users. The digital geologic database can be queried in many ways to produce a variety of derivative geologic maps. The data are not meant to be used at any scale larger than 1:125,000 (for example, 1:100,000 or 1:24,000)
Supplemental_Information:
This database consists of two major ArcInfo datasets. The CCC125K dataset contains arc features representing geologic contacts, faults, and folds; polygon features representing geologic rock (map) units; and regions representing allochthons. The CCCPNT dataset contains point features representing geologic point data of bedding, foliation, and fault attitude.
The datasets and related INFO look-up tables have been "exported" into ArcInfo interchange files with a .e00 file extension and will need to be imported for use. Lower case letters are consistently used in naming datasets and other files although they may be listed in uppercase letters for emphasis in this document and the Open-File Report it accompanies.

Data_Set_Credit:
D.M. Hirschberg (contractor), G.S. Pitts (contractor), and K.S. Bolm (USGS), scanned Dickinson's (1992) geologic map; registered the resulting image; digitized the arcs and points; captured and positioned the annotation, attributed the arcs, polygons, and points; defined and populated the look-up tables; prepared the data model; wrote the metadata; and produced the Open-File Report text. See the Process_Step sections for more details on these steps.
Native_Data_Set_Environment:
SunOS, 5.6, sun4u UNIX ArcInfo version 7.2.1
Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Attribute accuracy was verified by manual comparison of Dickinson's (1992) map with hard copy printouts.
Logical_Consistency_Report:
All lines and points on the source map representing geologic features were digitized as arcs (line segments) or points. These features were digitized once. Lines intersect only where intended. Overshoots (dangling arcs) and undershoots are present as represented in Dickinson's (1992) map. Line segments are a set of sequentially numbered coordinate pairs. No duplicate features exist nor duplicate points in a data string. Intersecting lines are separated into individual line segments at the point of intersection.
Polygon and chain-node topology present. All polygons have a label. All polygons close. Polygons intersecting the neatline are closed along the border. Segments making up the outer and inner boundaries of a polygon tie end-to-end to completely enclose the area. Point data are represented by two sets of coordinate pairs, each with the same coordinate values. All nodes are represented by a single coordinate pair which indicates the beginning or end of a line segment.
Completeness_Report:
None of the base map data (roads, washes, etc.) from Dickinson's (1992) map were digitized nor are represented in this database.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The horizontal positional accuracy is probably no better than +/- 100 meters.
The base for Dickinson's (1992) map is believed to be two U. S. Geological Survey 1:250,000 scale sheets spliced at the 32nd degree parallel and enlarged in scale to 1:125,000. Inaccuracies in the digital data would include inherent errors in Dickinson's (1992) map.

Process_Step:
Process_Description:
A paper copy of the geologic map (Dickinson, 1992) map was obtained and scanned at 300 dpi to create an 8-bit grayscale TIFF. The TIFF was registered to an ArcInfo coverage (dataset) of tics which had been mathematically generated in ArcInfo then projected to the Universal Transverse Mercator (UTM) projection.
Process_Date: 2000
Process_Step:
Process_Description:
A dataset (CCC125K) with arc and polygon topology was created from the same mathematically generated and projected set of tics. Items (fields) were added to its arc attribute table (.aat) and polygon attribute table (.pat) as needed.
Process_Date: 2000
Process_Step:
Process_Description:
Arcs were digitized and attributed on-screen in a 'heads-up' fashion with the image of the geologic map (Dickinson, 1992) as background. Each arc was attributed as soon as it was digitized. Attribute selections were entered via an on-screen menu for quality control purposes.
Process_Date: 2000
Process_Step:
Process_Description:
Check plots on mylar were produced for each sector. First, generic line symbols were used to proof the locational fidelity of the linework to Dickinson (1992). Later, check plots with symbolized lines were produced to check for attributional fidelity to the source map. Updates to the CCC125K dataset were made as needed.
Process_Date: 2000
Process_Step:
Process_Description:
Polygon topology was re-built. Polygons were attributed in the 'heads-up' fashion mentioned previously.
Process_Date: 2000
Process_Step:
Process_Description:
Check plots were produced to proof for polygon attributional fidelity to Dickinson (1992). Polygons were edited as needed.
Process_Date: 2000
Process_Step:
Process_Description:
An ArcInfo dataset (CCCPNT) with point topology was created. Items were added to the dataset's point attribute table (.pat) as needed.
Process_Date: 2000
Process_Step:
Process_Description:
Points were digitized and attributed in the same 'heads-up' fashion. Check plots were produced to proof locational, rotational, and other attributional qualities of the points.
Process_Date: 2000
Process_Step:
Process_Description:
Look-up tables for the CCC125K and CCCPNT datasets were defined and populated.
Process_Date: 2000
Process_Step:
Process_Description:
Rock unit annotation was captured for the CCC125K dataset and annotation strings were repositioned as needed. Dip values were captured for the necessary points in the CCCPNT dataset and repositioned as needed.
Process_Date: 2001
Process_Step:
Process_Description:
Arcs representing "plated" faults on the source map were re-coded as thrust faults (linecode = 171 or linecode = 173) in the arc attribute table (CCC125K.AAT). (Descriptions for the linecodes are given in the CCC125K.ST2 look-up table; however, for archival purposes, Dickinson's (1992) original line descriptions are given in the ORIG_DESC item in the CCC125K.AAT file.)
