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

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 3 rd party providers to the FAA

FAA Standards and Guidance Manuals AC 150/ “General Guidance and Specifications for Aeronautical Surveys: Establishment of Geodetic Control and Submission to the National Geodetic Survey” AC 150/ “General Guidance and Specifications for Aeronautical Surveys: Airport Imagery Acquisition and Submission to the National Geodetic Survey” AC 150/ “General Guidance and Specifications for Aeronautical Surveys: Airport Survey Data Collection and Geographic Information System Standards”

Geodetic Control Network CORS PACS Airport BM#1 BM#2 HARN SACS#1 SACS#2 FBN and BM ties must be observed simultaneously with both PACS Simplified Schematic 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.

Runway Survey

NAVAID Survey

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

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.
