PAPI Obstacle Clearance Surface (Aviation Tools)

サマリー

Creates a Precision Approach Path Indicator (PAPI) Obstacle Clearance Surface (OCS) based on the FAA Engineering Brief (EB) 95.

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.

使用法

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. They can also be generated in an existing polygon shapefile. If a feature class is selected for the Target OIS Features parameter value, it must have a vertical spatial reference.
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.
The Input Airport Control Point Feature parameter can be used to supply 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.

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
Runway Direction (オプション)	Specifies the end of the runway where the approach surface will be created. High Runway End Designator—The approach surface will be created at the high end of the runway. This is the default Low Runway End Designator—The approach surface will be created at the low end of the runway.	String
Length (オプション)	The length of the surface in miles. The default is 4.	Double
Divergence (オプション)	The divergence of the surface in degrees. The default is 10.	Double
Slope (オプション)	The slope of the surface in degrees. The default is 3.	Double
Distance From Threshold (オプション)	The distance from the threshold in feet. The default is 700.	Double
Start Height (オプション)	The start height of the surface in feet. The default is 35.	Double
Input Airport Control Point Feature (オプション)	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

コードのサンプル

PAPIObstacleClearanceSurface example (stand-alone script)

The following Python script demonstrates how to use the PAPIObstacleClearanceSurface function.

import arcpy

# Input Runway Feature Class
inFeatures = r"C:\data\ois.gdb\RunwayCenterline"

# Feature class that will contain the OIS surface
outFeatures= r"C:\data\ois.gdb\ObstructionIdSurface"

# Define surface dimensions
runway = "HIGH_RUNWAY_END_DESIGNATOR"
length = 4
divergence = 10
slope = 3
distance_from_threshold = 700
start_height = 35

# Generate PAPI Obstacle Clearance Surface
arcpy.aviation.PAPIObstacleClearanceSurface(inFeatures, outFeatures, runway,
                                            length, divergence, slope,
                                            distance_from_threshold, start_height)
