ICAO Annex 14 OFS OES (Aviation Tools)

Summary

Creates obstacle-free surfaces (OFS) and obstacle evaluation surfaces (OES) based on ICAO Annex 14 OFS OES specifications. These surfaces define the airspace around aerodromes to be free of obstacles and safeguard airspace so flight operations can be performed safely. This tool creates surfaces as a polygon or multipatch features.

Usage

  • The Input Runway Features parameter must be z-enabled.

  • This tool creates the obstruction identification surfaces (OIS) in an existing polygon or multipatch feature class. The OIS can also be generated in an existing polygon shapefile. If a feature class is used as the Target OIS Features parameter value, it must include a vertical spatial reference.

  • To create a .json file for the Custom JSON File parameter, use the CustomizeOIS.exe utility included in the Aviation Airports Product Data download available from My Esri.

  • The Input Runway End parameter uses two fields to determine the approach classification for each runway end. The approach guidance field APPROACHG determines the runway classification. The design group field DESIGNGR will determine the airplane design group. The runway end designator field RUNWAYENDD must be populated to match the corresponding Runway End. If displaced threshold points are included, surfaces will be constructed based on their x-, y-, and z-geometry instead of their corresponding Input Runway Features parameter endpoint.

  • The Input Airport Control Point Feature parameter can be used to supply x-, y-, and z-geometry for the Airport Elevation parameter.

  • The horizontal surface generated by this tool will be continuous across the multipatch feature.

Parameters

Label Explanation Data type

Input Runway Features

The input runway dataset. The feature class must be z-enabled and contain polylines.

Feature Layer

Target OIS Features

The target feature class that will contain the generated OIS.

Feature Layer

Input Runway

(Optional)

The input runway feature layer. The Runway Designator and Width fields are used to determine the surface dimensions.

Feature Layer

Input Runway End

(Optional)

The input runway end feature layer. The approach guidance field APPROACHG is used to determine the runway classification. The design group field DESIGNGR is used to determine the airplane design group. The runway end Designator field RUNWAYENDD must be populated with the corresponding runway end value.

Feature Layer

Input Airport Control Point Feature

(Optional)

Supplies x-, y-, and z-geometry for displaced threshold features. If displaced thresholds are included, surfaces will be constructed based on their x-, y-, and z-geometry instead of their corresponding runway feature endpoint.

Feature Layer

Custom JSON File

(Optional)

The import configuration, in JSON format, that will be used to create the custom OIS.

File

Include Merged Surfaces

(Optional)

Specifies whether merged surfaces will be generated.

  • Checked—All the surfaces will be generated for the merged surfaces, as well as merged conical and horizontal surfaces. This is the default.

  • Unchecked—Surfaces will not be generated for the merged surfaces.

Boolean

Derived output

Label Explanation Data type

Output OIS Features

The output feature class with the output OIS features.
