Description:
Abstract:
The geology of the Greer 7 1/2-minute quadrangle, Oregon
County, Missouri was mapped from 1995 through 1996 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.
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.

Scanned raster images of stable-base map separates,
vectorized, edited, and attributed coverages to produce
DLG-style vector coverages of hypsography, hydrology, and
transportation layers.
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.
