The Aviation OIS toolbox contains tools that generate obstruction identification surfaces (OIS) according to different specifications.
| Tool name | Description |
|---|---|
| FAA 18B | Creates obstruction identification surfaces based on the FAA 18B specification. These surfaces describe airspaces that should be free of obstructions. Surfaces are used to support planning and design activities. The type, function, and dimension of a surface differ by runway classification. This tool creates surfaces as polygon or multipatch features or triangulated irregular networks (TINs). |
| FAA FAR 77 | Creates obstruction identification surfaces based on the FAA FAR 77 specification. These surfaces describe airspace segments that are clear of obstructions. The type, function, and dimension of a surface differs by runway classification. This tool creates surfaces as polygon or multipatch features, or triangulated irregular networks (TINs). |
| ICAO Annex 14 | Creates obstruction 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 obstruction may project into an airspace. The type, function, and dimension of a surface differ by runway classification. This tool creates surfaces as polygon or multipatch features, or triangulated irregular networks (TINs). |
| ICAO Annex 15 | Creates obstruction identification surfaces (OIS) based on the ICAO Annex 15 specification (Areas 2a, 2b, and 2c). These surfaces assist in determining the height restriction or removal of obstacles that pose a hazard to air navigation in and around an aerodrome. This tool creates surfaces as a polygon or multipatch features. |
