Description:

Abstract:

This study presents the results from a ground-based gamma-ray survey of bedrock outcrops in the 7.5-minute Barre West quadrangle, Vermont. Data were collected with a Geofyzika 512-channel portable gamma-ray spectrometer (GS-512) with a sodium iodide, thallium-activated scintillation probe. During the summer of 2003, 493 data points were collected at outcrops throughout the Barre West quadrangle. Two detailed transects were conducted at two roadcuts along Interstate 89 at Exits 7 and 8 to identify outcrop-scale differences in gamma radiation emissions.

Purpose:

The report was published as part of a study of fractured bedrock aquifers. The digital data are intended for use by all government, academic, commercial, or other agencies in need of digital geologic map information.

Supplemental_Information:

The GIS database is accompanied by a text pamphlet, in PDF format, and a readme.txt file.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

All attributes digitized during the creation process were verified by displaying the points in the database with respect to the USGS 7.5-minute topographic map, but no formal tests were performed.

Logical_Consistency_Report:

These data are believed to be logically consistent, though no tests were performed.

Completeness_Report:

The point locations were delineated on a USGS 7.5-minute topographic map based on observations and GPS locations. The features in the database are not based on legal parcels or definitions.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The data were created on a USGS 7.5-minute topographic map at 1:24,000 scale. Therefore, the horizontal accuracy is assumed to be within National Map Accuracy Standards, with a horizontal accuracy of 45.6 feet at the 95% confidence level. Locational information in the field was provided by general purpose hand-held GPS receivers using the code correlation method.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

The data were delineated on a USGS 7.5-minute topographic map at 1:24,000 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.

Process_Step:

Process_Description:

Location information was provided by general purpose hand-held GPS receiver (Garmin eTrex Venture). Point data were collected with GPS. Data from the gamma ray spectrometer was exported to Excel and combined in ArcView version 3.3, converted into shapefiles, and then imported into Arc/Info. Database files were edited as a coverage in Arc/Info and later converted to shapefiles. The projected point coverage was unprojected to geographic coordinates and exported to SDTS format.
