Split Features (Topographic Production Tools)

Summary

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

Usage

Caution:

This tool modifies the input data. See Tools that modify or update the input data for more information and strategies to avoid undesired data changes.

The Cutting Features parameter value must have at least one feature selected. A warning will be returned if no features are selected.
Target features will be divided into multiple features at any point where they intersect the source features.
The Cutting Features parameter value will have new vertices added at every point where they intersect the target features.
Run the Integrate tool using the Cutting Features and Target Features parameter values to help ensure spatial integrity before using this tool. This is important when complex polygon features are involved.

Label	Explanation	Data type
Cutting Features	The cutting features that will be used to split the target features where they intersect the target feature class geometries.	Feature Layer
Target Features	The features that will be divided by the cutting features.	Feature Layer
Use Target Z Values	Specifies whether the z-value from the source or target will be used. Checked—The z-value from the source or target will be used. Unchecked—The z-value from the source or target will not be used. This is the default.	Boolean

Derived output

Label	Explanation	Data type
Output Features	The features that were divided by the Cutting Features value.	Feature Layer

arcpy.topographic.SplitFeatures(cutting_features, target_features, use_target_z)

Name	Explanation	Data type
cutting_features	The cutting features that will be used to split the target features where they intersect the target feature class geometries.	Feature Layer
target_features [target_features,...]	The features that will be divided by the cutting features.	Feature Layer
use_target_z	Specifies whether the z-value from the source or target will be used. `USE_TARGET_Z`—The z-value from the source or target will be used. `DONT_USE_TARGET_Z`—The z-value from the source or target will not be used. This is the default.	Boolean

Derived output

Name	Explanation	Data type
out_feature_layer	The features that were divided by the `cutting_features` value.	Feature Layer

Code sample

SplitFeatures example 1 (stand-alone script)

This script demonstrates how to use the SplitFeatures function to split single target features based on the cutting features.

# Name: SplitFeatures_sample1.py
# Description: Splits a single target features based on the cutting features

# Import System Modules
import arcpy

# Setting Local Variables
cutting_features = r'C:\Temp\MapIndex.gdb\Index_Polygons'
target_features = r'C:\Temp\Test.gdb\Builtup_Area_Polygons;C:\Temp\Test.gdb\Vegetation_Polygons'

# Setting selection on cutting features
selected_feature = arcpy.management.MakeFeatureLayer(cutting_features, 'AOI').getOutput(0)
arcpy.management.SelectLayerByAttribute(selected_feature, 'NEW_SELECTION', "PRODUCT_ID = 'V795X16573'")

# Splitting features based on the selected cutting feature
arcpy.topographic.SplitFeatures(cutting_features, target_features, 'DONT_USE_TARGET_Z')

SplitFeatures example 2 (stand-alone script)

This script demonstrates how to use the SplitFeatures function to split all feature classes in a geodatabase based on the cutting features.

# Name: SplitFeatures_sample2.py
# Description: Gets all feature classes in a geodatabase and splits them on the selected cutting feature

# Import System Modules
import arcpy
import os

# Setting Local Variables
cutting_features = r'C:\Temp\MapIndex.gdb\Index_Polygons'
target_database = r'C:\Temp\Test.gdb'

# Getting feature classes from the target geodatabase that are managed in a feature dataset
target_features = r''
arcpy.env.workspace = target_database
datasets = arcpy.ListDatasets('*', 'Feature')
for dataset in datasets:
    fclasses = arcpy.ListFeatureClasses('*', '', dataset)
    for fclass in fclasses:
        desc = arcpy.Describe(fclass)
        if desc.shapeType in ('Polygon', 'Polyline'):
            target_features += os.path.join(target_database, dataset, fclass) + ';'
target_features = target_features[:-1]

# Setting selection on cutting features
selected_feature = arcpy.management.MakeFeatureLayer(cutting_features, 'AOI').getOutput(0)
arcpy.management.SelectLayerByAttribute(selected_feature, 'NEW_SELECTION', "PRODUCT_ID = 'V795X16573'")

# Splitting all features in a database based on the selected cutting feature
arcpy.topographic.SplitFeatures(selected_feature, target_features, 'DONT_USE_TARGET_Z')
