Publication_Date: 20000000 Title: Geologic Map of the Powder Mill Ferry Quadrangle, Shannon and Reynolds Counties, Missouri, I-2722 Publication_Information: Publication_Place: Reston, VA Publisher: U.S. Geological Survey Online_Linkage: Description: Abstract: The geology of the Powder Mill Ferry 7 1/2-minute quadrangle , Shannon and Reynolds Counties, Missouri was mapped from 1997 through 1998 as part of the Midcontinent Karst Systems and Geologic Mapping Project, Eastern Earth Surface Processes Team. The map supports the production of a geologic framework that will be used in hydrogeologic investigations related to potential lead and zinc mining in the Mark Twain National Forest adjacent to the Ozark National Scenic Riverways (National Park Service). Digital geologic coverages will be used by other federal and state agencies in hydrogeologic analyses of the Ozark karst system and in ecological models. Purpose: The purpose of this geologic map and database is to support and be part of a three-dimensional geologic framework study of south-central Missouri. The framework will be used to assess environmental impacts of lead and zinc mining in the Mark Twain National Forest on the hydrologic system of the Ozark National Scenic Riverways. Supplemental_Information: Bedrock, Quaternary , residual units, faults, and structural data are each stored in separate coverages. See readme.txt file for explanation of organization.

Authors as well as USGS map editors performed separate reviews. Logical_Consistency_Report: These data are believed to be logically consistent, though no rigorous formal tests were performed. Polygon coverages were queried to screen for empty or inconsistent values. Line geometry is topologically clean. Completeness_Report: Geologic map units were collected and digitized at a resolution appropriate for portraying on a base of 1:24,000 scale. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The data were created by delineating the boundaries from stable overlays on a USGS 7.5 minute Topographic Map at 1:24000 scale. Therefore, the mapped horizontal accuracy is assumed to be within National Map Accuracy Standards, with a horizontal accuracy of 45.6 feet at the 95% confidence level. As with all things human, potential exists for error in location by the mapper in the field especially as all ground locations were plotted manually without aid of GPS, surveying, or other precision locating equipment. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The data were delineated off a USGS 7.5 minute Topographic Map at 1:24000 scale. Therefore, the vertical accuracy is assumed to be within National Map Accuracy Standards, with a vertical accuracy of 11.9 feet at the 95% confidence level. As with all things human, potential exists for error in location by the mapper in the field especially as all ground locations were plotted manually without aid of GPS, surveying, or other precision locating equipment. Measurement of some vertical positions (altitude) was aided by barometric altimeter readings, but with accuracy of only about plus or minus 20 feet. Most vertical positions are derived from the plotted horizontal position on the topographic base.

Process_Step: Process_Description: The original map data was manually transferred to separate stable media overlays registered to a stable-base USGS 7.5 minute topographic map. The overlays were scanned using Anatech Scansmith sofware driving an Eagle 4080 ET scanner to produce .tiff files. The .tiff files were then processed via GTX Corporation's GTX OSR V4.0 software to produce .dxf vector files. The .dxf files were imported to ESRI Arc/Info and transformed to match the geographic coordinates of the quadrangle. The coverages were then edited to eliminate dangles, gaps, and other errors, and built to the appropriate topology. Items were created for features in each coverage and attributed as appropriate. Test plots were generated with data sets plotted over other data and base topography and hydrology for review by USGS map editors and authors. Errors were corrected by on-screen digitizing, and corrections were checked again by map editors and authors. A separate database file for polygon attributes was generated and populated in Microsoft Access 2000, exported as a .bdf file, converted in Arc/Info to an Info file, then joined to each polygon coverage using map_unit as the join item. Each coverage was then projected to either (UTM, Zone 15, NAD83, GRS80) or (Geographic, DD, NAD27, Clarke1866) and exported to an Arc .e00 export file. Base coverages included with the data (hypsography, hydrography, and roads) were downloaded over the WWW from the USGS GLIS site, converted from SDTS to Arc/Info coverages, built, then projected to match the data, and then exported to .e00 format also.
