This is a Vector data set. It contains the following vector data types (SDTS terminology):
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest .01. Longitudes are given to the nearest .01. Latitude and longitude values are specified in Decimal Degrees.
The horizontal datum used is Unknown.
The ellipsoid used is Clarke 1866.
The semi-major axis of the ellipsoid used is 6378206.4.
The flattening of the ellipsoid used is 1/294.98.

The data was generated to help in understanding the seismotectonic hazards in the vicinity of the lower Wabash Valley. This data complements similar data collected in the vicinity of New Madrid, MO (US Geological Survey Open-File Report 95-0574, available via ftp at <http://pubs.usgs.gov/of/1995/ofr-95-0574/>)

The coverage contains no attributes beyond those generated by ARC/INFO.
Original scale 1:500,000. The scanned images were not georeferenced,
and an unknown amount of error was introduced during the
georeferencing process.
No tests performed. Accuracy of locations on the Geologic Map of
Kentucky is unknown. The relative accuracy in this representation is
the same as on that source map. Absolute locations are within several
km, although this is estimated. Faults were compared to those on
1:250,000 scale Paducah Quadrangle Geologic Map and were
adjusted to connect where it appeared they should.
all faults included on the Geologic Map of Kentucky within the map area are represented in this cover
Chain-node topology present.
