Open Government & The MAR

Of governments and geeks (Economist) - In 2008 the city of Washington, DC, a trailblazer in the field of open data, sponsored a contest called “Apps for Democracy”—with $50,000 in costs and prize money—which produced 47 applications.

A decent percentage of the open data that is made available in Washington, DC uses the Master Address Repository to acquire accurate location information.

Improvements to the Intersection Table


Currently the MAR Intersection Table only contains 'regular' at grade intersections. It does not include intersections where there is an overpass or underpass or ramps (such as ramps off of INTERSTATE 295). This is a shortcoming of the MAR and is being remedied. Situations occur at these location also and they need to be locatable using the MAR.
There are two phases for adding underpasses, overpasses and ramps to the Intersection Table:


Phase I
  • Add Underpasses (ex: FIRTH STERLING AVENUE SE UNDER INTERSTATE 295)
  • Add Overpasses (ex: INTERSTATE 295 NORTHBOUND OVER FIRTH STERLING AVENUE SE)
Phase II
  • Add Ramps (ex: NORTHBOUND NORTH CAPITOL STREET NE AND RAMP FROM EASTBOUND IRVING STREET NE)
Currently the overpasses and underpasses have been digitized and are undergoing testing. In order to easily find these location the code for the MAR Web Services will also need to be updated. Many of the ramps still need to be digitized. The overpasses and underpasses should be in production by the end of February.

Duplicate Address Problem at 3233 15th Place SE - Still Not Resolved

The duplicate address problem at 3233 15th Place SE has still not been resolved by DCRA. That is that both a cemetery and a townhouse use the address 3233 15th Place SE. The recommended solution is changing the address of the townhouse to 3233 1/2 15th Place SE. The cemetery had the address of 3233 15th Place SE before the townhouse was built, and thus the cemetery's claim to the address takes precedence.

DCRA needs to resolve this issue by informing the owner of the townhouse of the need to change their address. The homeowner then needs to physically change the address number on the exterior of their townhouse. Additionally, DCRA also needs to contact the various agencies to inform them of the new address 3233 1/2 15th Place SE.
