The digital files from the Census Bureau were converted into ARC/INFO files. Selected attributes were joined to the TIGER files from the Census 2000 Summary File 1. Each county coverage was checked against county census block grid maps on the Census Bureau website (www.census.gov Maps=>Map Products=>Census2000 block maps=>st37_northcarolina).
With the exception of dissolving polygons and projecting data,
no other positional changes were made by NC CGIA.
Linework for the 2000 Census files is based predominantly on the Census Bureau's TIGER Line files. The coverages were dissolved on the tract item and selected attributes joined from the 2000 Summary File 1 by NC CGIA.
The ARC/INFO files have been "cleaned" and "built" to ensure complete topology.
