Description:

Abstract:

This open-file report is a digital representation of the Dickinson (1993, 1998, 2000) remapping of the post-Mid- Miocene Quiburis Formation in southeastern Arizona. It delineates constituent facies of the Formation throughout the San Pedro trough.

Purpose:

This dataset was developed to provide geologic map GIS of the Quiburis Formation for use in future spatial analysis by a variety of users. These data can be printed in a variety of ways to display various geologic features or used for digital analysis and modeling. It was digitized from 1:24,000-scale maps. The digital database is not meant to be used or displayed at any scale larger than 1:24,000 (for example, 1:12,000).

Data_Set_Credit:

Karen S. Bolm and Tasha Lewis digitized these data from scans of the Dickinson (1993, 1998, 2000) maps made by G. Stephen Pitts. Douglas M. Hirschberg provided programs to aid in attribution of the data, and William R. Dickinson provided attribute information, assisted in the editing, and resolved problems resulting from the combination of three maps.

Native_Data_Set_Environment:

SunOS, 5.6, sun4u UNIX ARCINFO version 7.2.1 ARCINFO version 8.1 ArcView version 3.2 for Windows

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

When the digitized maps were printed and compared to the Dickinson (1998) mylar originals, a considerable north/south distortion was discovered. The mylar originals were compared to topographic maps of the same area and it was determined that the distortion was due to the mylars becoming stretched during repetitive copy processing. Because of this distortion of the Dickinson(1998) maps, it is difficult to estimate the accuracy of this digital map.
Accuracy of the digitized versions of the Dickinson (1993, 2000) maps was verified by manual comparison of the source with hard copy printouts and plots and with screen images.

Logical_Consistency_Report:

Polygon and chain-node topology present.
The Dickinson (1993, 1998, 2000) maps were digitized by Karen S. Bolm and Tasha Lewis. Attributes have the same meaning throughout the maps. In some cases, however, units and lines symbols were not consistent from one map to the other. In those cases, one attribute had to be chosen over the other.

Completeness_Report:

Some of the units at the edge of the Dickinson (1993, 1998, 2000) maps were labeled, but accurate contacts were not defined. In those cases, either units were attributed as "unmapped" or not included on the digital version or new contacts were added by William R. Dickinson. Some labeling, which could not be easily included as attribution, was omitted. Also, some of the symbolization chosen for this dataset is different than that used by Dickinson (1993, 1998, 2000). This was done to standardize products.
The original Dickinson (1993, 1998, 2000) maps were drawn on topographic background. Digital versions of those topographic maps are not included with this dataset.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Due to distortions in the original maps, it was impossible to test the accuracy of the digital mapping of the Dickinson (1998) maps. Based on testing of the the Dickinson (1993, 2000) maps, it is estimated that the features are accurate to within 24 meters.

Process_Step:

Process_Description:

Twelve 1:24,000-scale mylar maps that comprise three Dickinson (1993, 1998, 2000) reports were scanned by G. Stephen Pitts on a Scanographics CF500/4 scanner using ScanServ 3.5.1 software. Pitts mathmetically generated a tic file with tics of the study area spaced at 2.5' intervals, and Karen S. Bolm rectified the scanned images using ESRI ArcView Image Analysis. Bolm and Tasha Lewis digitized the linework using Geologic Mapping Tools, an ArcView extension developed by William R. Kelley (contractor at the U.S. Geological Survey's Western Regional Mineral Resources Team, Spokane Field Office). Lines and polygons were attributed by Bolm in ArcInfo 7.2.1.
Points were digitized from the scanned images using digpnt.aml, and attribution was retrieved for annotation using getdip.aml, both programs written by Douglas M. Hirschberg.

Process_Date: 2000-2001

Process_Step:

Process_Description:

After review, it was decided to merge the three Dickinson (1993, 1998, 2000) maps into a single spatial digital database. The coverages were merged by Karen S. Bolm, and discrepancies were resolved by her and William R. Dickinson. Some additional contacts had to be added to separate units that were originally on the edges of the mapped areas. Duplicate lines and points were removed. Maps were plotted at 1:24,000 and checked for errors.

Overview_Description:

Entity_and_Attribute_Overview:

The "Spatial Digital Database for the Geology of the San Pedro River Basin in Cochise, Gila, Graham, Pima, and Pinal Counties, Arizona" report (quib24k.pdf) contains a detailed description of each attribute code and a reference to the associated map symbols in the map source materials. The database includes a geologic linework arc attribute table, quib24k.aat, that relates to the quib24k.co3 (contact look-up table), quib24k.st2 (structure look-up table), quib24k.lgu (linear geologic units look-up table), and quib24k.ref (source reference look-up table) files and a rock unit polygon attribute table, quib24k.pat, that relates to the quib24k.ru (rock unit look-up table) and quib24k.ref (source reference look-up table) files. Associated with this database is a geologic marker point attribute table, quib24kp.pat that relates to quib24kp.sym (symbol description look-up table) and quib24kp.ref (source reference look-up table).
