Generate OIS Intersection (Aviation)

获得 Aviation Airports 许可后可用。

摘要

Creates the most restrictive (lowest) surfaces within the extent of all collective surfaces. Obstruction identification surfaces (OIS) determine which objects 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 new subsurfaces that constitute the overlapping portions of surfaces can have 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.

使用情况

• The Input OIS Features must be z-enabled.

• The Output OIS Features must be z-enabled.

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

参数

对话框

标注	说明	数据类型
Input OIS Features	The input OIS features. The feature class must be multipatch.	Feature Layer
Output OIS Features	The updated feature class containing the meshed OIS with the lowest z-value.	Feature Layer
Create Multipart Feature (可选)	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})

名称	说明	数据类型
in_ois_features [in_ois_features,...]	The input OIS features. The feature class must be multipatch.	Feature Layer
out_ois_features	The updated feature class containing the meshed OIS with the lowest z-value.	Feature Layer
multipart_feature (可选)	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

代码示例

GenerateOISIntersection example (Python window)

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

import arcpy
 
# set gp environment
arcpy.CheckOutExtension("Airports")
 
# Input Obstruction Identification Surface Feature Class
inOISFeatures = r"C:\data\ois.gdb\ObstructionIdSurface"
 
# Feature class that will contain the OIS surface
outOISFeatures = r"C:\data\ois.gdb\MeshedSurface"
 
# Create multipart feature
createMultipart = "MULTIPART"
 
# Processing Generate OIS Intersection tool
arcpy.GenerateOISIntersection_aviation(inOISFeatures, outOISFeatures, createMultipart )
 
arcpy.CheckInExtension("Airports")

环境
