[ Open Data DC ] – Centerlines

Street Roadway Centerlines. A single line, segmented at all intersections (alley , service road, drive, street, and driveway centerline types), representing each street in the District. They follow the general trend of the street and do not deviate due to parking lanes, turning lanes, etc. and contain address ranges for geocoding. The street GIS database includes five different street road types: street centerline, alley, drive, ramp and service road. All DC GIS data is stored and exported in Maryland State Plane coordinates NAD 83 meters. This layer contains complete theoretical address ranges.
