NOAA/NGS Aeronautical Survey Program NGS ORIENTATION Mark Howard October, 2008
How NGS supports the FAA • Provide products and services to FAA (ATO-R) through an inter-agency agreement • Provide positional, height, and orientation information to the FAA in support of the National Airspace System (NAS) and safe navigation • Develop standards, guidelines, tools, and models designed to assist surveyors conducting aeronautical surveys • Quality Review aeronautical survey data submitted by 3rd party providers to the FAA
Standards and Guidance Manuals AC 150/5300-16 “General Guidance and Specifications for Aeronautical Surveys: Establishment of Geodetic Control and Submission to the National Geodetic Survey” AC 150/5300-17 “General Guidance and Specifications for Aeronautical Surveys: Airport Imagery Acquisition and Submission to the National Geodetic Survey” AC 150/5300-18 “General Guidance and Specifications for Aeronautical Surveys: Airport Survey Data Collection and Geographic Information System Standards” FAA 405 http://www.ngs.noaa.gov/AERO/aerospecs.htm

High-Resolution Imagery • High-Resolution photography of the Airport is collected for the entire study area being surveyed. • Imagery is used in the photogrammetric process for determining the height of obstructions and airport feature compilation.
Obstruction Survey Numerous types of surveying techniques are used to determine the latitude, longitude, and height of obstructions within the FAA Part 77 and Area Navigation Approach Obstruction Identification Surfaces
Photogrammetric Survey All survey information brought together into a Digital Photogrammetric Workstation
Digital Airport Obstruction Chart • Geo-spatial file (ESRI shape file format) • Metadata • Geo-PDF • Data in UDDF format http://www.ngs.noaa.gov/AERO/eAOC/eAOC.htm
FY09 Aeronautical Surveys 17 AOC/AC-18B Surveys 117 ANA-LPV Approach Surveys 47 NAVAID Surveys
Transitioning to a QA Role • Focus on quality review services • Collaborate with FAA in developing Aeronautical Survey Standards • Support commercial surveyors performing aeronautical surveys • Develop procedures, guidelines and models • Convene workshops and training seminars

Summary • Continue to conduct aeronautical surveys and maintain current core capabilities. • Increased support to FAA in a Quality Review Role • Continue to refine Quality Review process • Continue to develop models and tools designed to support surveyors conducting aeronautical surveys. • Continue to evaluate and research new technologies for increasing efficiency in mapping programs.
