An overview of the Obstruction Identification Surfaces toolset

Available with Aviation Airports license.

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

Tool	Description
Create Curved Approach	Creates curved approach obstacle identification surfaces (OIS) based on the supported specifications in ArcGIS 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 in existing 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 notification requirements for objects affecting navigable airspace. The type, function, and dimension of a surface differ by its runway classification. This tool creates surfaces as a polygon or multipatch features.
Generate OIS Intersection	Creates the most restrictive (lowest) surfaces within the extent of all collective surfaces. Obstruction identification surfaces (OIS) determine which objects are vertical obstructions. An object is considered a vertical obstruction if it penetrates the OIS surface. Surfaces are used to support planning and design activities.
ICAO Annex 14	Creates obstruction identification surfaces (OIS) based 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 a 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 a 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.
Light Signal Clearance Surface	Creates a Precision Approach Path Indicator (PAPI) Obstacle Clearance Surface (OCS) based on the FAA Engineering Brief (EB) 95.
PAPI Obstacle Clearance Surface	A PAPI OCS determines which objects are vertical obstructions. An object is considered a vertical obstruction if it penetrates the PAPI OCS. Surfaces are used to support planning and design activities.
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.
