Description:
Abstract:
The geology of the Stegall Mountain 7 1/2-minute quadrangle, Shannon and Carter Counties, Missouri was mapped from 1997 through 1999 as part of the Midcontinent Karst Systems and Geologic Mapping Project, Eastern Earth Surface Processes Team. 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.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
All polygon atributes were checked for correct values against original field data by the geologists.
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: These data are complete at a resolution of 1:24,000
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.
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 vertical accuracy is assumed to be within National Map Accuracy Standards, with a horizontal accuracy of 11.9 feet at the 95% confidence level.

Process_Description:
A digital geographic base layer was created by georegistering then rectifying a .tiff image of the USGS 7.5 minute quadrangle. RMS error was required to be less than 3 meters (10 ft) in ground units. Geologic data was added as layers in ArcView 3.2 from field maps and notes by the authors. The shape files were converted to coverages and edited to eliminate dangles, gaps, and other errors, then were 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.
