NOAA/NGS Aeronautical Survey Program

NGS ORIENTATION

Mark Howard

October, 2008


How ngs supports the faa
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”

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


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
Photogrammetric Survey

All survey information brought together into a Digital Photogrammetric Workstation

Summary
Summary surveys and accuracy assessments

  • 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.
