DC GIS Announces the New Master Address Repository Sample Client

Story at a Glance 

The MAR sample client is built using a service-oriented-architecture design, easily integrated across District government applications.


The District's Master Address Repository is a comprehensive database of building addresses and other location identifiers in the District of Columbia.  Each address in the database is assigned a unique Address Identification Number (AID), map coordinates, and other useful information.  The MAR was recently presented to the Geographic Information Systems (GIS) community at the 2006 ESRI International User Conference.

The MAR:

  • facilitates analysis across District systems and agencies.
  • acts as a local gazetteer employing spell checks and aliases names.
  • informs users of alias names and condo units associated with addresses.
  • is built and distributed using the District's service-oriented-architecture.
