Download the MAR Geocoder

As of October 2021, the MAR Desktop Geocoder is no longer supported by OCTO. This means that although the geocoder is still available and generally continues to work for some users, OCTO is no longer devoting resources to support bug fixes nor enhancements. We encourage users to begin using the MAR Web Geocoder. It offers the same functionality without dependencies associated with using a desktop client. The user guide is available here.
The MAR Web Geocoder (version 1) was released in September 2022 and we continue to improve it. Support for the MAR Web Geocoder is available to District agencies and their contractors. Limited support is available for non-DC government organizations or public individuals. The tool was tested against common datasets successfully. Other limitations and errors may exist.
