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 0.000000. Longitudes are given to the nearest 0.000000. Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is North American Datum of 1927.
The ellipsoid used is Clarke 1866.
The semi-major axis of the ellipsoid used is 6378206.400000.
The flattening of the ellipsoid used is 1/294.978698.
Sequential unique whole numbers that are automatically generated.
Coordinates defining the features.

This geologic map was prepared as part of a study of digital methods and techniques as applied to complex geologic maps.
Christiansen, Love and , 1985, geologic scribe sheets.
Data sources used in this process:
The accuracy of the attributing is unknown
The USGS does not have National Mapping Accuracy Standards for data produced at the 1:500,000-scale.
Unknown, but likely to be as complete in attributing as the Love and Christiansen geologic map.
Polygon topology present and Arc/Info reports matching labels/polygons Line toplogy also present.
Are there legal restrictions on access or use of the data?
- Access_Constraints: none
- Use_Constraints: scale is 1:500,000 and should not be used outside that range
