Split Features

Résumé

Splits features for any number of polyline or polygon target feature classes using the cutting features and inserts points on the cutting feature.

Utilisation

• Cutting features must have at least one feature selected.

• Target features will be divided into multiple features at any point where they intersect the source features.

• Source features will have new vertices added at every point where they intersect the target features.

Syntaxe

SplitFeatures_defense (cutting_features, target_features, use_target_z)

Paramètre	Explication	Type de données
cutting_features	The source features used to split target features at intersection points of the feature class geometries.	Feature Layer
target_features [target_features,...]	The features that will be divided by the cutting features.	Feature Layer
use_target_z	Determines the source of the z-value from the source or target. USE_TARGET_Z —Uses the z-value from the source or target. DONT_USE_TARGET_Z —Does not use the z-value. This is the default.	Boolean

Exemple de code

SplitFeatures example (stand-alone script)

This script demonstrates how to use SplitFeatures.

# Name: SplitFeatures_Example.py
# Description: Split road features by AOI polygons
# Requirements: Esri Defense Mapping solution

# Import the Arcpy module
import arcpy

# Check out Defense Mapping extension
arcpy.CheckOutExtension('defense')

# Set up the gp environment
arcpy.env.overwriteOutput = 1
arcpy.env.workspace = r"C:\Data\MGCP_TRD4.gdb"
arcpy.env.scratchWorkspace = r"C:\Data\SplitFeatures.gdb"

# Declare paths to AOI features and polyline features
AOIFeatures = r"C:\Program Files (x86)\ArcGIS\EsriDefenseMapping\Desktop10.2\ReferenceData\MapIndex.mdb\MapIndex\TLM50_Index"
polylineFeautres = r"C:\Data\MGCP_TRD4.gdb\MGCP\RoadL"

# Create feature layers of the AOI
arcpy.management.MakeFeatureLayer(AOIFeatures, "AOIFeatures")

# Select specific AOIs
selection = "NRN = 'E732X57714'"
arcpy.management.SelectLayerByAttribute("AOIFeatures", "NEW_SELECTION", selection)

# Execute Split Features tool
arcpy.defense.SplitFeatures("AOIFeatures", polylineFeautres, "USE_TARGET_Z")
