Data sources used in this process:
Data sources used in this process:
Congressional districts shapefiles were acquired from the General Assembly, Information Systems Division. Block assignments were based on the plan ratified by the General Assembly in 2001 and effective for the 2002 elections. The shapefiles were converted to ARC/INFO coverages and projected to Stateplane NAD83 meters projection, resulting in a statewide districts coverage.
No positional changes were made by NC CGIA.
These data represent the boundaries of 2001 Congressional districts in North Carolina. Each district is labeled with unique district identification number as supplied by the General Assembly, Information Systems Division data.
Using ESRI's ARC/INFO GIS software, the dataset was built for arc and polygon topology using the "build" command. The data set was then cleaned with a fuzzy tolerance of 1 meter. Topology has not been edited since the last build or clean.
Are there legal restrictions on access or use of the data?
