Data Quality Information:

Attribute accuracy report:

Horizontal Positional Accuracy Report:

Approximate horizontal accuracy is 51 meters, assuming source data meets National Map Accuracy Standards.

Source information:

Originator: U.S. Census Bureau
Publication date: 1992
Title: 1992 Tiger/Line Files
Edition: 1992
Source scale denominator: 100000
Source contribution:: The coordinates were copied from the TIGER files. The TIGER attribute FMCD was used to determine which lines were Minor Civil Division boundaries.
Calendar date: 1992

Process step:

Convert TIGER files to Arc/Info format and project them from geographic coordinates to Albers.


Process date: 05/01/1996

Process step:

Dissolve TIGER county coverages on the FMCD attribute. Mapjoin all the coverages and dissolve again. Rename the FMCD attribute FIPS.


Process date: 05/02/1996

Process step:

Join the place names from the look-up table to the Polygon Attribute Table.
