An overview of the Obstruction Identification Surfaces toolset

This toolset contains tools that create obstruction identification surfaces based on the specifications outlined in FAA FAR 77, ICAO Annex 14, and ICAO Annex 15.

Tool name	Description
FAA FAR 77	Creates obstacle identification surfaces based on the FAA FAR 77 specification. These surfaces describe airspace segments that are clear of obstacles. The type, function, and dimension of a surface differs by runway classification. This tool creates surfaces as polygon features.
ICAO Annex 14	Creates obstacle identification surfaces based on the ICAO Annex 14 specification. These surfaces define areas of airspace around an aerodrome. Each area defines the limits to which an obstacle may project into an airspace. The type, function, and dimension of a surface differs by runway classification. This tool creates surfaces as polygon features.
ICAO Annex 15	Creates obstacle identification surfaces based on the ICAO Annex 15 specification. These surfaces define areas of airspace around an aerodrome. Each area defines the limits to which an obstacle may project into an airspace. This tool creates surfaces as polygon features.
