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

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.

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

FAA Airports Surveying-GIS Program

Provider establishes and submits geodetic control


Provider acquires and submits geo-referenced digital imagery


Airport contracts for

Survey using AIP



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

  • 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.
