Generate OIS Intersection (Aviation)

Mit der Aviation Airports-Lizenz verfügbar.

Mit der Aviation Charting-Lizenz verfügbar.

Zusammenfassung

Creates the most restrictive (lowest) surfaces within the extent of all collective surfaces. Obstruction identification surfaces (OIS) determine objects that are vertical obstructions. An object is considered a vertical obstruction if it penetrates the OIS surface. Surfaces are used to support planning and design activities.

Many airports have more than one runway and each runway has a set of obstruction identification surfaces. Supporting automatic generation of subsurfaces that constitute the overlapping portions of surfaces can produce a better visualization and a more accurate analysis for an airport. To generate a single set of surfaces, multiple sets of surfaces are needed. This tool creates surfaces as multipatch features.

Verwendung

• The Input OIS Features parameter must be z-enabled.

• The Output OIS Features parameter must be z-enabled.

• All of the Input OIS Features parameter values must have the same projected coordinate system.

Parameter

Dialogfeld

Beschriftung	Erläuterung	Datentyp
Input OIS Features	The input OIS features. The feature class must be a multipatch.	Feature Layer
Output OIS Features	The updated feature class containing the meshed OIS with the lowest z-value.	Feature Layer
Create Multipart Feature (optional)	Specifies whether multipart features will be created in the output. Multipart features are composed of more than one physical part that only references one set of attributes. Create multipart features—Multipart features will be created. This is default. Do not create multipart features—Adjacent triangulated multipart features will be created as individual features.	Boolean

Python

arcpy.aviation.GenerateOISIntersection(in_ois_features, out_ois_features, {multipart_feature})

Name	Erläuterung	Datentyp
in_ois_features [in_ois_features,...]	The input OIS features. The feature class must be a multipatch.	Feature Layer
out_ois_features	The updated feature class containing the meshed OIS with the lowest z-value.	Feature Layer
multipart_feature (optional)	Specifies whether multipart features will be created in the output. Multipart features are composed of more than one physical part that only references one set of attributes. MULTIPART—Multipart features will be created. This is default. MERGE_ADJACENT—Adjacent triangulated multipart features will be created as individual features.	Boolean

Codebeispiel

GenerateOISIntersection example (stand-alone script)

The following stand-alone script demonstrates how to use the GenerateOISIntersection function with a single OIS as input.

import arcpy

# Check out the Airports extension
arcpy.CheckOutExtension("Airports")

# Input Obstruction Identification Surface feature class
inOISFeatures = r"C:\data\ois.gdb\ObstructionIdSurface"

# Feature class that will contain the output OIS surface
outOISFeatures = r"C:\data\ois.gdb\MeshedSurface"

# Create multipart feature
createMultipart = "MULTIPART"

# Run the Generate OIS Intersection tool
arcpy.GenerateOISIntersection_aviation(inOISFeatures, outOISFeatures, createMultipart)

# Check in the Airports extension
arcpy.CheckInExtension("Airports")

GenerateOISIntersection example (stand-alone script)

The following stand-alone script demonstrates how to use the GenerateOISIntersection function with two OIS feature classes as input.

import arcpy

# Check out the Airports extension
arcpy.CheckOutExtension("Airports")

# Input Obstruction Identification Surface feature classes
inOISFeature_set1 = r"C:\data\ois.gdb\ObstructionIdSurface_set1"
inOISFeature_set2 = r"C:\data\ois.gdb\ObstructionIdSurface_set2"

# Feature class that will contain the output OIS surface
outOISFeatures = r"C:\data\ois.gdb\MeshedSurface"

# Create multipart feature
createMultipart = "MULTIPART"

# Run the Generate OIS Intersection tool against a multivalue string
arcpy.GenerateOISIntersection_aviation([inOISFeature_set1, inOISFeature_set2], outOISFeatures, createMultipart)

# Check in the Airports extension
arcpy.CheckInExtension("Airports")
