The District of Columbia Geographic Information System (DC GIS) is coordinated by the Office of the Chief Technology Officer (OCTO) and provides District agencies and the public a 'one-stop shop' for geospatial data and enterprise applications. As a technology, GIS empowers policymakers and implementers with data and application tools that support better decision-making and performance.
