Data sources used in this process:
Data sources used in this process:
House districts shapefiles were acquired from the General Assembly, Information Systems Division, ratified Nov. 25, 2003. The shapefiles were converted to ARC/INFO coverages, cleaned with a dangle and fuzzy tolerance of .0001 and projected from Decimal Degrees projection 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 2003 House 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.
