DC Geographic Information System Program

The DC GIS program works to improve the quality and lower the cost of services provided by the DC government, through the District's collective investment and effective application of geospatial data and systems. Furthermore, DC GIS reaches beyond the DC government by continuing to make DC GIS data freely and publicly available to the fullest extent possible in consideration of privacy and security.

The program is coordinated by the Office of the Chief Technology Officer (OCTO) GIS group. It provides DC agencies and the public a “one-stop shop” for disseminating geospatial data and enterprise applications. Nationally, it is in the top tier of comparable programs, and its accessible data and services surpass what is available in many states and city jurisdictions.
