Developing a Regional Routable Centerline for Fairfax County GIS Mapping Standards

This project outlines the creation of a regional routable centerline for Fairfax County, focusing on GIS and mapping standards. Key elements include implementing persistent unique IDs for tracking relationships between parent and child IDs. The project aims to integrate attributes such as speed limits, road classifications, one-way designations, and ramp naming. Additional considerations include modeling intersections and addressing border streets and elevated crossings. Establishing a comprehensive methodology ensures accurate and consistent mapping throughout the region.
