Use the MAR Web Geocoder to convert a list of addresses or place names to a set of complete addresses with spatial attributes like x,y or latitude/longitude coordinates. The batch geocoder enables the bulk geocoding of location records against DC’s Master Address Repository (MAR).
Start by viewing the MAR Web Geocoder user guide. Support for the MAR Web Geocoder is available to District agencies and their contractors through octohelps.dc.gov. Limited support is available for non-DC government organizations or public individuals.
