Road segments representing centerlines of all roadways or carriageways in Chatham County, NC. This representation of the road centerlines support address geocoding and mapping. It also serves as a source for public works and other agencies that are responsible for the active management of the road network. This feature class is maintained by the E-911 Addressing Specialist for Chatham County within the addressing dataset of the ChathamGIS enterprise SDE database. The geometry of this feature class is imported and fields matched to the RoadCenterline feature class located in the reference dataset of the ChathamGIS SQL database to adhere to the LGIM data structure nightly through a scripting process.
