NGS, in accordance with a series of interagency agreements with the Federal Aviation Administration (FAA), provides airport geodetic control, runway, navigational aid, obstruction and other aeronautical data that is critical to the operation of the National Airspace System (NAS). The FAA uses the data to develop instrument approach and departure procedures, determine maximum takeoff weights, update aeronautical publications, and airport planning and engineering studies.Most of this data is source information obtained using field and photogrammetric survey methods. NGS acquires aerial photography of most commercial and many general aviation airports in the United States to support several types of aeronautical surveys, including Airport Obstruction Chart (AOC), Operational Evolution Plan (OEP), and Congressional (CGR) and, until recently, Area Navigation Approach (ANA). The high resolution photographs are used to perform a photogrammetric analysis of the Obstruction Identification Surface (OIS), determine areas obstructing the OIS, delineate aircraft movement areas and associated airport features, and are useful when performing ground surveys. Over 1,000 airports have been flown and photographs for these locations are currently available through the NGS photo library. The National Geodetic Survey (NGS) provides position, height, and orientation information needed for safe navigation of the National Airspace System (NAS). These surveys provide critical information about runway, aids to navigation, obstructions and airport features. The Federal Aviation Administration uses the data to establish airport approach and departure procedures, determine maximum takeoff weights, update aeronautical publications, and airport planning and construction studies. underDevelopment NGS Communications and Outreach Branch (301) 713-3242 (301) 713-4172 ngs.infocenter@noaa.gov pointOfContact NGS Communications and Outreach Branch (301) 713-3242 (301) 713-4172 ngs.infocenter@noaa.gov custodian asNeeded Remotely Sensed Imagery/Photos theme NOS Data Explorer Topic Category ANA AOC Airport Navigation Approach Airport Obstruction Chart CGR Congressional FAA Federal Aviation Administration NAS National Airspace System OEP Operational Evolution Plan aerial photograph aerial photography aeronautical data aeronautical survey airport geodetic control imagery remote sensing theme Alaska Region Central Region Eastern Region FAA regions Great Lakes Region New England Region Northwest Mountain Region Southern Region Southwest Region United States Western Pacific Region place DOC/NOAA/NOS/NGS > National Geodetic Survey, National Ocean Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

These photographs are of metric quality for mapping purposes. The most current photogrammetric processing techniques need to be used. Documenting the process used to minimize the effects due to scale variations and optical distortions allows the user of the data obtained from photographs to determine its accuracy. Completeness Report The photographs adequately represented ground truth at the time they were obtained. These photographs have not been processed to reduce the errors inherent in the photogrammetric technique. Conceptual Consistency These photographs are being presented "as is". They have undergone no processing to reduce the errors that are inherent in the photogrammetric techniques. These photographs should be assumed to have errors due to scale variation and optical distortions. The National Geodetic Survey (NGS), in accordance with a series of interagency agreements with the Federal Aviation Administration (FAA), provides airport geodetic control, runway, navigational aid, obstruction, and other aeronautical data that is critical to the operation of the National Airspace System. NGS acquires aerial photography for many airports in the United States to support aeronautical surveys. The high resolution photographs are used to perform a photogrammetric analysis of the Obstruction Identification Surface (OIS), determine areas obstructing the OIS, delineate aircraft movement areas and associated airport features, and are useful when performing ground surveys.Photography is acquired when weather conditions, sun angle, and, when applicable, water levels are optimal to ensure the photographs will be suitable for a variety of purposes using standard photogrammetric techniques.Of the 1,000 airport locations in the NGS library approximately 300 photographs have been scanned and are available online through the Aeronautical Survey Program's (ASP) Airport Photo Gallery. The image is scanned directly from the film positive at 100 dpi.
