You may be surprised to learn that the National Ocean Service is responsible for surveying and reviewing aeronautical data in support of the nation's airports and airspace.
NOAA has played a role in our nation's aviation industry since the early 1900s. Today, the National Geodetic Survey (part of NOS) administers the Aeronautical Survey Program. This program provides highly accurate position, height, and orientation information needed for safe air navigation.
NGS has been performing aeronautical surveys since the 1920s. More recently, NGS' responsibilities have expanded to reviewing surveys by commercial surveyors to ensure the aeronautical data meets Federal Aviation Administration (FAA) standards and specifications. These surveys provide critical information about airport features and about obstructions and aids to navigation. FAA uses this information to establish airport approach and departure procedures, determine maximum takeoff weights, update aeronautical publications, and conduct airport planning and construction studies.
