Create Curved Approach (Aviation)

获得 Aviation Airports 许可后可用。

获得 Aviation Charting 许可后可用。

描述

Creates curved approach obstacle identification surfaces (OIS) based on the supported specifications in ArcGIS Aviation. These curved approach surfaces are based on an input flight path and the information in the selected specification, for example, ICAO Annex 15, FAA 18B and classification. This tool creates surfaces in existing polygon or multipatch features.

使用方法

• 输入跑道要素参数必须启用 Z 值。

• The surfaces generated are based on the Specification and Runway Classification parameter values.

• The tool creates a curved approach surface in an existing polygon or multipatch feature class. If Output OIS Features is a feature class, it must have a vertical spatial reference.

• The tool uses a flight path ID field (PATHID) for Output OIS Features.

• 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.

参数	说明	数据类型
in_runway_features	The input runway dataset. The feature class must be z-enabled and contain polylines.	Feature Layer
in_flightpath_features	The polyline features that define curved approaches to the specified runways.	Feature Layer
target_ois_features	The target feature class that will contain the generated OIS.	Feature Layer
specification	Specifies the approach surface specification. ETOD —ICAO Annex 15 (ETOD) OLS —ICAO Annex 14 (OLS) FAR77 —FAA regulations part 77 (FAR77) 18B —FAA Advisory circular 150/5300_18B (18B) 13A —FAA Advisory circular 150/5300_13A (13A)	String
runway_classification	The runway classification of the approach surface. The option used for the Specification parameter (specification in Python) will determine the available options for the this parameter.	String
custom_json_file （可选）	The import configuration, in JSON format, that creates the custom OIS.	File
threshold_offset （可选）	The distance offset from the runway end point. The threshold will be applied in the units of the input.	Double

派生输出

名称	说明	数据类型
out_ois_features	The updated feature class containing the generated OIS.	Feature Layer

代码示例

CreateCurvedApproach example (stand-alone script)

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

import arcpy

# set gp environment
arcpy.CheckOutExtension("Airports")

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

# Input Flight Path Feature Class 
inFlightPathFeatures= r"C:\data\ois.gdb\TakeOffClimb"

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

# Speicfication
specification = "FAR77"

# Runway Classification
runway = "PRECISION_INSTRUMENT_RUNWAY"

# JSON
customJSON = r"C:\data\customOIS.json"

# Treshold Offset
thresholdOffset = 0

# Generate FAA 77 OIS
arcpy.CreateCurvedApproach_aviation(inFeatures, inFlightPathFeatures,
                                    outFeatures, specification, runway, customJSON, thresholdOffset)
