Creating LAX FAA Part 77 - Obstruction Identification Surfaces (OIS) u
Track: Aviation
Authors: Abdel Khineche

Our Goal at EFMD was to produce within a short amount of time the OIS (Obstruction Identification Surfaces) for the 4 Runways at LAX Airport and make the data / layers available to LAWA Planning engineers through our Web-based Intranet application AEGIS (Airport Engineering GIS).
We decided to try the Esri Airport GIS extension - Obstruction Identification Surfaces toolset - to create the Surfaces, based on the specifications outlined in FAA 18B, FAA FAR 77, ICAO Annex 14, and ICAO Annex 15.
