Resumen

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

Uso

• El parámetro Entidades de pista de entrada debe estar habilitado para z.

• When Runway Classification is set to Vertical Guidance, the output transitional surface will be split into four sections by a line perpendicular to the runway centerline.

• When Runway Classification is set to Vertical Guidance, the output conical and horizontal surfaces will be split into sections by a meridian and a parallel. The meridian intersects the Airport Elevation Point and the centerpoint of the runway centerline. The parallel runs perpendicular to the meridian through the centerpoint of the runway centerline.

  Nota:

  In the absence of Airport Control Point Feature Class parameter values, the split will be based on the runway endpoint and runway centerpoint. The split will then draw a line from the runway endpoint and runway centerpoint and form a line parallel and perpendicular to the runway centerline.

• This tool creates the OIS in an existing polygon or multipatch feature class. It can also be generated in an existing polygon shapefile. If a feature class is selected for Target OIS Features, it must have a vertical spatial reference.

• To create a JSON file for the Custom JSON File parameter, use the CustomizeOIS.exe file that is part of the ArcGIS Aviation data package 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.

• OIS tools are flexible and accept a variety of input and output feature class types. For more information, see the OIS Input and Output schemas.

Parámetros

Cuadro de diálogo

Etiqueta	Explicación	Tipo de datos
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 obstruction identification surfaces.	Feature Layer
Runway Classification	Specifies the runway classification of Input Runway Features. Non vertical guidance type 1—A runway designed for visual maneuvers, nonvertically guided operations, and instrument departure procedures. Non vertical guidance type 2—A specially prepared hard surface (SPHS) runway designed for visual maneuvers, nonvertically guided operations, and instrument departure procedures. SPHS runways have a primary surface that extends 200 feet beyond each end of the runway. Vertical guidance—A runway that uses precision guidance systems to support aircraft approach and landing.	String
Length of High Runway End Clearway (Opcional)	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 (Opcional)	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 (Opcional)	The highest elevation on any of the runways of the airport. The value should be given in the vertical coordinate system linear units of the target feature class. If no value is given, the highest point on the Input Runway Features will be used.	Double
Include Merged Surfaces (Opcional)	Indicates whether merged horizontal and conical surfaces are included in the OIS in addition to the regular surfaces. Checked—Include merged surfaces in the OIS output. This is the default. Unchecked—Do not include merged surfaces in the OIS output.	Boolean
Custom JSON File (Opcional)	The import configuration, in JSON format, that creates the custom OIS.	File
Input Airport Control Point Feature (Opcional)	The point features containing an Airport Elevation feature, displaced threshold features, or both. Values provided for the Airport Elevation parameter will take precedence over these point features.	Feature Layer
