- Description:
-
- Abstract:
- Preliminary bedrock geologic map of the Stepens City 7.5
minute quadrangle, Clarke, Frederick, and Warren, Counties, VA, USA.
- Purpose:
- This map was produced to provide basic geologic
information for land-use planning and ground-water aquifer studies.
This data will be incorporated into a 3-dimesional model of the
hydrogeologic framework of the lower Shenandoah Valley.

- Data_Quality_Information:
-
- Attribute_Accuracy:
-
- Attribute_Accuracy_Report:
- All polygon atrtributes 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: The data are complete at a
resolution of 1:24,000
- Positional_Accuracy:
-
- Horizontal_Positional_Accuracy:
-
- Horizontal_Positional_Accuracy_Report:
- These data were collected with the aid a Trimble
GeoXm GPS reciever with a accuracy rating of within 3 meters.
- Vertical_Positional_Accuracy:
-
- Vertical_Positional_Accuracy_Report:
- These data were plotted on a USGS 7.5 minute
topographic map at 1:24,000 scale. Therefore, the mapped vertical
accuracy is assumed to approach National Map Accuracy Standards, with a
horizontal accuracy of 11.9 feet at the 95% confidence level.

- Process_Description:
- All structural measurements were done in the field
with a Brunton geologic transit read to the nearest degree. 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
captured in the field as point locations via a Trimble GeoXM
GPS-enabled handheld computer running ArcPad GIS software. The shape
files were converted to ArcGIS geodatabases and edited over the basemap
in ArcMap 9.0. Test plots were generated and provided to the authors
for comparison to the original data and corrections made to all errors
identified. The feature classes were then exported back to shapefiles
for distribution.
