The North Carolina Department of Transportation - GIS Unit developed the digital GIS Municipal Boundaries - Powell Bill 2008 data set from the 2008 Powell Bill boundaries which incorporated municipalities in North Carolina that participate in the Powell Bill Program are required to submit to NCDOT on a regular basis. Boundaries of municipalities which do not participate in the Powell Bill Program are also included in the layer. These boundaries are periodically updated from maps and GIS data submitted by the local towns or counties to the North Carolina Department of Transportation - GIS Unit. Sources for the boundaries vary in scale and format based on what was supplied.
This data were created to assist governmental agencies and others in making resource management decisions through use of a Geographic Information System (GIS). Municipal boundaries are recognized as a base cartographic layer for location analysis.
2008 Powell Bill Information: 506 Cities/Towns are participating in the Powell Bill Program. 45 Cities/Towns are not participating in the Powell Bill Program, but are incorporated and are included in the layer. Total: 551 Cities/Towns. Powell Bill Participants are responsible for submitting paper maps to the NCDOT Powell Bill Administration annually, if there have been changes to their boundaries since the previous year. For the Powell Bill Participants, the NCDOT GIS Unit updates the boundaries for the municipalities that have submitted maps. For Non-Powell Bill Participants, the NCDOT GIS Unit updates the boundaries periodically. Sources for these updates come from contacting the local government agencies. Attributes for all municipalities are updated on an annual basis, where applicable.

Local Government Agencies
The North Carolina Department of Transportation collects town and city maps of various scales from municipalities participating in the Powell Bill Program. Maps and GIS Layers of municipalities that do not participate in the Powell Bill Program are also collected periodically.
The North Carolina Department of Transportation - GIS Unit Data Conversion Group digitizes the boundaries. The digital files are compared for accuracy against the originals.
Attributes are updated in a separate database and are joined to the boundaries after the digitizing process is complete.
