Сводка

Creates a Light Signal Clearance Surface (LSCS) based on the FAA Engineering Brief (EB) 95.

A LSCS determines which objects are vertical obstructions. An object is considered as vertical obstruction if it penetrates the LSCS. Surfaces are used to support planning and design activities.

Использование

Параметр Входные объекты взлетно-посадочной полосы должен поддерживать z-значения.
This tool creates the Obstruction Identification Surface (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.
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.

Parameter	Объяснение	Тип данных
in_features	The input runway dataset. The feature class must be z-enabled and contain polylines.	Feature Layer
target	The target feature class that will contain the generated obstruction identification surfaces.	Feature Layer
runway_direction (Дополнительный)	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 (Дополнительный)	The length of the surface in miles. The default value is 8.	Double
divergence (Дополнительный)	The divergence of the surface in degrees. The default value is 14.	Double
slope (Дополнительный)	The slope of the surface in degrees. The default value is 1.	Double
distance_from_threshold (Дополнительный)	The distance from the threshold in feet. The default value is 1000.	Double

LightSignalClearanceSurface example (stand-alone script)

The following Python window script demonstrates how to use the LightSignalClearanceSurface tool.

import arcpy

arcpy.CheckOutExtension("Airports")

# 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 = 8
divergence = 14
slope = 1
distance_from_threshold = 1000
first_papi_light = 60
last_papi_light = 120
start_height = 35

# Generate Light Signal Clearance Surface
arcpy.LightSignalClearanceSurface_aviation(inFeatures, outFeatures, runway,
                                           length, divergence, slope,
                                           distance_from_threshold,
                                           first_papi_light, last_papi_light,
                                           start_height)
