Aeronautical Survey Program

Aeronautical Data

The National Geodetic Survey (NGS), in accordance with a series of interagency agreements with the Federal Aviation Administration (FAA), provides runway, navigational aid, obstruction, and other aeronautical data that is critical to the operation of the National Airspace System. Most of this data is source information obtained using field survey and photogrammetric methods.

Digital delivery is available through ASCII files in the "Universal Data Delivery Format (UDDF)". Hard copy delivery is available through the products described in "Other Aeronautical Products".
