资源简介：
The current road centerline system was established in 1992 by MSAG Data Consultants and is based on a grid based numbering system. Since 2001, all new roads are GPS'd, typically to an accuracy of about 3 feet. Other road centerlines are updated with aerial imagery as needed. When three or more addresses are off of one driveway it becomes a new road. The E-911 Ordinance and E-911 Guidance documents address the process for naming roads. This layer contains attribution for road class type and other routing data.
