Zusammenfassung

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.

Verwendung

  • Der Parameter Eingabe-Lande-/Startbahn-Features muss Z-aktiviert sein.

  • 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 Airport Elevation parameter has a default value of 0. If you use an elevation value greater than 0, it takes precedence and overrides any existing airport elevation value read from the Input Airport Control Point Feature parameter.

  • The Input Airport Control Point Feature parameter can be used to supply x-, y-, and z-geometry for the Airport Elevation parameter, displaced threshold point features, or both. If displaced threshold points are included, surfaces will be constructed based on their x-, y-, and z-geometry instead of their corresponding Input Runway Feature parameter endpoint.

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

Parameter

BeschriftungErläuterungDatentyp
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
Surfaces to Generate

Specifies the type of surface that will be generated.

  • Obstacle free surfacesAn OFS will be generated. This provides a free volume of airspace in critical surroundings of the runway.
  • Obstacle evaluation surfacesAn OES will be generated. This provides the volume of airspace where obstacles could impact the operations and where their impact needs to be evaluated.
String
Runway Classification

Specifies the classification of the runway.

  • Non instrument runwayThis runway classification intended for the operation of aircraft using visual approach procedures.
  • Non precision instrument runwayThis runway classification is designed for a nonprecision instrument approach procedure.
  • Precision instrument runwayThis runway classification is designed for an instrument approach procedure.
String
Airplane Design Group

Specifies the airplane design group that will be used to generate surfaces.

  • IThe airplane design group I will be used.
  • IIAThe airplane design group IIA will be used.
  • IIBThe airplane design group IIB will be used.
  • IICThe airplane design group IIC will be used.
  • IIIThe airplane design group III will be used.
  • IVThe airplane design group IV will be used.
  • VThe airplane design group V will be used.
String
Length of High Runway End Clearway
(optional)

The length of the area at the high end of the runway. The unit of measurement is based on the input runway features.

Double
Length of Low Runway End Clearway
(optional)

The length of the area at the low end of the runway. The unit of measurement is based on the input runway features.

Double
Airport Elevation
(optional)

The highest elevation on any of the runways of the airport. The value must be in the vertical coordinate system linear units of the target feature class. If no value is provided, the highest point from the Input Runway Features parameter value will be used.

Double
Runway Direction
(optional)

Specifies the end of the runway where the approach surface will be created.

  • High end to low endThe approach surface will be created at the high end of the runway to the low end. If a displaced threshold point exists at the high end of the runway, that point will be honored when creating the OIS.
  • Low end to high endThe approach surface will be created at the low end of the runway to the high end. If a displaced threshold point exists at the low end of the runway, that point will be honored when creating the OIS.
  • Both endsThe approach surface will be created at both the low end and high end of the runway.
String
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
Custom JSON File
(optional)

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

File
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.
