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 .001. Longitudes are given to the nearest .001. 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 scale of original data varies 1:24,000 to 1:250,000 depending on various maps that were used in the compilation by Illinois Basin Consortium personnel.
all data sent included
This cover had the most reliable locations and quality of the three fault covers used to portray faults in the lower Wabash Valley. Where this cover overlapped data from Illinois Basin Consortium compilation (ibcflt) or Geologic Map of Kentucky (kyflt), this data was used to erase those covers.
