Faulty Addresses in DC Government Datasets

In DC Government databases, like other municipal government databases, the address is the most common geographic piece of information. DC Government databases contain tens of thousands of incorrect address in all sorts of datasets. Some of these incorrect addresses cause many problems as these records often cannot be located. Incorrect addresses also cause problems when comparing different datasets to each other based on the address. For example in a DC Net database there was an address of 500 C Street NW for the DC Superior Court but in actuality the address should be 500 Indiana Avenue NW.

It is my hope that the various DC Agencies take the issue of correct addresses seriously. DC GIS is working with various agencies such as Office of Tax & Revenue, Department of Parks & Recreation on address issues.
