An overview of the Obstruction Identification Surfaces toolset

The Obstruction Identification Surfaces toolset contains tools to create obstruction identification surfaces based on various specifications.

Tool nameDescription

Create Curved Approach

Creates curved approach obstacle identification surfaces (OIS) based on the supported specifications in ArcGIS for Aviation. These curved approach surfaces are based on an input flight path and the information in the selected specification, for example ICAO Annex 15, FAA 18B and classification. This tool creates surfaces such as a polygon or multipatch features.

FAA 13A

Creates obstruction identification surfaces (OIS) based on the FAA Advisory Circular 150/5300-13A specification. These approach and departure surfaces are designed to protect the use of the runway in both visual and instrument meteorological conditions near the airport and are used to support planning and design activities. The type, function, and dimension of a surface differ by its runway classification. This tool creates surfaces such as a polygon or multipatch features.

FAA 18B

Creates obstruction identification surfaces (OIS) based on the FAA Advisory Circular 150/5300-18B specification. These OIS assist in the identification of possible hazards to air navigation and critical approach/departure obstructions within the vicinity of the airport and are used to support planning and design activities. The type, function, and dimension of a surface differ by its runway classification. This tool creates surfaces such as a polygon or multipatch features

FAA FAR 77

Creates obstruction identification surfaces (OIS) based on the FAA Part 77 specification. This regulation establishes standards and notiļ¬cation requirements for objects affecting navigable airspace. The type, function, and dimension of a surface differs by its runway classification. This tool creates surfaces as polygon or multipatch features.

ICAO Annex 14

Creates obstruction identification surfaces based (OIS) on the ICAO Annex 14 specification. These surfaces define the airspace around aerodromes to be free of obstacles so operations can be performed safely. This tool creates surfaces as polygon or multipatch features.

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 polygon or multipatch features.

ICAO Annex 4

Creates obstruction identification surfaces (OIS) based on the ICAO Annex 4 specification for the Precision Approach Terrain chart.

Unified Facilities Criteria

Creates obstruction identification surfaces based on the Unified Facilities Criteria UFC 3-260-01 that is prescribed by MIL-STD 3007. These surfaces provide planning, design, construction, sustainment, restoration, and modernization criteria for the United States Department of Defense. Surfaces are created as polygon or multipatch features.
