Split Features (Defense Mapping)

Summary

Defense Mapping tool that splits features in batch for any number of polyline or polygon target feature classes using the cutting features and inserts points on the cutting feature.

Usage

• 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.

Syntax

SplitFeatures_defense (cutting_features, target_features, use_target_z)

Parameter	Explanation	Data Type
cutting_features	The source features used to split target features at intersection points of the feature class geometries.	Feature Layer
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. YES —Uses the z-value from the source or target. NO —Does not use the z-value. This is the default.	Boolean

Code Sample

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, "YES")
