Description:
Abstract:
The bedrock geology was mapped to study the geologic and tectonic history of the State of Vermont. The digital data are intended for use by all government, academic, commercial, or other agencies in need of digital geologic map information.
Purpose:
The bedrock geology was last mapped at a statewide scale 50 years ago at a scale of 1:250,000 (Doll and others, 1961). The 1961 map was compiled from 1:62,500-scale or smaller maps. The current map was created to integrate more detailed (1:12,000- to 1:24,000-scale) modern mapping with the theory of plate tectonics to provide a framework for geologic, tectonic, economic, hydrogeologic, and environmental characterization of the bedrock of Vermont.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
All attributes digitized during the creation process were verified by displaying the lines and points in the database with respect to the USGS 30 x 60 minute topographic base map (1:100,000 scale), but no formal tests were performed.
Logical_Consistency_Report:
These data are believed to be logically consistent, though no tests were performed. Geometry is topologically clean.
Completeness_Report:
The geologic contacts were delineated on USGS 1:100,000-scale topographic base maps from published and unpublished observations. 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 delineated on USGS 30 x 60 minute topographic maps at 1:100,000 scale. The horizontal accuracy of solid lines and points is considered "approximate" and dotted lines are considered "concealed", according to the terminology set forth in the FGDC Digital Cartographic Standard for Geologic Map Symbolization (2006) <http://ngmdb.usgs.gov/fgdc_gds/geolsymstd.php>
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The data were delineated on a USGS 30 x 60 minute topographic maps at 1:100,000 scale. Therefore, the vertical accuracy of the base map is assumed to be within National Map Accuracy Standards. Vertical accuracy of the geologic data was not tested.
Lineage:
Process_Step:
Process_Description:
The geology was compiled at 1:100,000-scale from source maps ranging from 1:12,000- to 1:250,00-scale. The line and polygon data were first drafted with pen and ink on stable-base mylar greenlines of the 1:100,000-scale topographic base maps. Mylar greenlines were scanned and auto-vectorized in Adobe Illustrator. Film positive separates of the published topographic base maps were scanned and mosaicked in Illustrator. Illustrator line work was converted to Autocad DXF vector files and imported to Arc/Info version 9.3. Point data were heads-up digitized. Attribute data were compiled in Excel and joined with the shapefiles in ArcMap. Line and polygon data were edited in Arc/Info and converted to shapefiles. In ArcMap, layer files were created from the shapefiles. In ArcToolbox, Google Earth KMZ files were created from the layer files. Cartography was done in Adobe Illustrator CS4.
