Abstract

Air Space locations. The dataset contains locations and attributes of Air Space in the Washington Metropolitan Area, created as part of the DC Geographic Information System (DC GIS) for the D.C. Office of the Chief Technology Officer (OCTO) and participating D.C. government agencies.

A database provided by the National Geospatial-Intelligence Agency (NGA) identified Air Space guideliines for the DC Metro Area. The data specifically comes from NGA's Digital Aeronautical Flight Information File (DAFIF).

All DC GIS data is stored and exported in Maryland State Plane coordinates NAD 83 meters.

METADATA CONTENT IS IN PROCESS OF VALIDATION AND SUBJECT TO CHANGE.
