  1. NOAA/NGS Aeronautical Survey Program NGS ORIENTATION Mark Howard October, 2008

  2. 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

  3. 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

  4. FAA Part 77 Surfaces FAA Part 77 Surfaces as depicted in FAA Spec. No. 405

  5. Geodetic Control Runway Data NAVAID Data Airport Imagery Obstruction Chart Obstruction Data

  6. Aeronautical Survey Process FAA Aerial Survey Geodetic Control Survey Prelim Photo Survey / Data Mining Field Survey FAA Final Photo Survey FAA

  7. BM#1 PACS BM#2 SACS#1 HARN Airport SACS#2 Geodetic Control Network CORS FBN and BM ties must be observed simultaneously with both PACS • PACS and SACS monuments are positioned and tied to the National Spatial Reference System through GPS observations. Simplified Schematic

  8. 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.

  9. Runway Survey

  10. NAVAID Survey

  11. 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

  12. Photogrammetric Survey All survey information brought together into a Digital Photogrammetric Workstation

  13. PhotogrammetricAnalysis

  14. 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

  15. FY09 Aeronautical Surveys 17 AOC/AC-18B Surveys 117 ANA-LPV Approach Surveys 47 NAVAID Surveys

  16. 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

  17. Survey Submission – Upload UDDF FAA Third Party Survey System (TPSS)

  18. NGS TPSS Validation Process UDDF File Provider re-submits TPSS Web Site NGS validation NGS Download NGS UDDF validation tool Resolve General items only YES Report NO Critical or Fatal items NGS email notification to POC

  19. FAA Airports Surveying-GIS Program Provider establishes and submits geodetic control AC-16 Provider acquires and submits geo-referenced digital imagery AC-17 Airport contracts for Survey using AIP Funds FAA Web portal to track surveys Once imagery is approved by NGS Provider conducts Aeronautical Survey in accordance with AC-18 Submits Deliverables to the FAA Web Portal NGS reports findings to FAA NGS performs Quality Review FAA

  20. Photo Control Archive

  21. Photo Control Points collected to support Photogrammetric surveys and accuracy assessments Positions NAD 83 / NAVD 88 Accuracy Horizontal: 3 Decimeters Vertical: 5 Decimeters Sketches, ground photographs

  22. 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.
