The map supports the production of a geological 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 geological 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 surficial units, faults, structure contour, karst, structural and miscellaneous points, and base map data are each stored in separate coverages. See readme.txt file for explanation of organization.

DATA_QUALITY_INFORMATION

Attribute_Accuracy: Attribute_Accuracy_Report: Attribute accuracy is tested by manually comparing hard-copy plots of the digital data with the source materials. The author as well as USGS map editors performed separate reviews. Logical_Consistency_Report: These data are believed to be logically consistent, though no rigorous formal test 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: These data were created by delineating the boundaries from inked lines on a stable-base USGS 7.5 minute topographic map at 1:24,000 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 most ground locations were plotted manually without aid of GPS, surveying or other precise locating equipment. Horizontal positional accuracy was enhanced at most data points by use of a Paulin altimeter with time/temperature correction for fairly accurate vertical positions. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: These data were created by delineating the boundaries from inked lines on a stable-base USGS 7.5 minute topographic map at 1:24,000 scale. Therefore, the mapped horizontal accuracy is assumed to be within National Map Accuracy Standards, with a horizontal 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 many ground locations were plotted manually without the aid of GPS, surveying, or other precision locating equipment. Measurement of most vertical positions (altitude) was aided by use of a Paulin altimeter with time/temperature correction . Other vertical positions derived from the plotted horizontal position on the topographic base.

Process_Step: Process_Description: The map data was inked onto a stable-base USGS 7.5 minute topographic map. The map was scanned using Anatech Scansmith software driving an Eagle 4080 ET scanner to produce .tiff files. The .tiff files were then processed via GTX Coporation'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 and provided to the author for comparison to the original data and corrections made to all errors identified. A separate database file for map_unit polygon attributes was generated and populated in Microsoft Access 2000, exported as a .dbf 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 (NAD27, Clarke 1866) and exported to an Arc .e00 export files.
