Description:

Abstract:

This dataset is a polygon shapefile representing unassessed Mesozoic (Triassic) basins of the Eastern U.S. The shapefiles were digitized off of a printed map that was done by the Delaware Geological Survey. The scale of the map that was digitized is 1:1,000,000. The map demonstrates the maximum extent of several basins, and their qualitatively assessed potential for coal. These basins have not been quantitatively assessed by the U.S. Geological Survey.

Purpose:

This dataset was compiled to update the Coal Fields Map of the Conterminous United States, OFR 96-092. It was included to demonstrate potential for coal basins and exploration in areas that have not previously been considered.

Technical reviews for this publication were provided by Leslie Ruppert, Christopher Garrity, Susan Tewalt, Lee Osmonson, James Luppens and James Coleman.

Native_Data_Set_Environment:

Microsoft Windows Vista Version 6.1 (Build 7601) Service Pack 1; ESRI ArcCatalog 9.3.0.1770

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:: Attribute accuracy was tested by manual comparison of the source with georeferenced digital printouts of the original publication, hard copy printouts and/or symbolized display of the digital geologic data on an interactive computer graphic system.

Logical_Consistency_Report:

Map elements were visually checked for overshoots, undershoots, duplicates, polygon closure and proper attribution.

Completeness_Report:

Data set complete. No data was intentionally omitted from the hard copy and digital source maps.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:: The digital file and shapefile was digitized by hand, with a RMS error not exceeding .005 when coordinating the digitizer. Visual comparison of the basins with the digital geologic map of North America displayed some offset, with the maximum being around 1 km.

Process_Description:

The Mesozoic basins shapefile was digitized by hand from the paper map Benson (1992). The coverage was projected from UTM 18 with a datum of NAD 1927 into geographic, and the datum was converted using the ESRI NADCON datum conversion. The coverage was exported as a shapefile and the polygons were populated with attributes.
