Simplify By Tangent Segments (Editing)

Summary

Simplifies polygon and line features by removing collinear and co-circular vertices from straight and curved lines. If the line or arc segments between vertices are tangent to each other, the vertices between the segments will be removed.

Illustration

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.

• This tool can be used to remove extra vertices on straight and curved lines. For example, in some cases, vertices are added to features for topology validation. These cases include when features intersect with other features or touch other features. Over time, the extra vertices can accumulate and affect the outcomes of future edits to the features.

Parameters

Dialog

Label	Explanation	Data Type
Input Features	The features that will be simplified. The features can be lines or polygons.	Feature Layer
Maximum Allowable Offset	The maximum distance the resulting output feature geometries can deviate from the input feature geometries. If the geometries of the resultant features deviate by more than the specified offset from the input feature geometries, the vertices will not be removed and the features will remain unaltered.	Linear Unit

Derived Output

Label	Explanation	Data Type
Output Features	The updated features.	Feature Layer

Python

arcpy.edit.SimplifyByTangentSegments(in_features, max_offset)

Name	Explanation	Data Type
in_features	The features that will be simplified. The features can be lines or polygons.	Feature Layer
max_offset	The maximum distance the resulting output feature geometries can deviate from the input feature geometries. If the geometries of the resultant features deviate by more than the specified offset from the input feature geometries, the vertices will not be removed and the features will remain unaltered.	Linear Unit

Derived Output

Name	Explanation	Data Type
out_feature_class	The updated features.	Feature Layer

Code sample

SimplifyByTangentSegments example (Python window)

The following Python window script demonstrates how to use the SimplifyByTangentSegments function to simplify line features using a 0.5 foot offset.

import arcpy
arcpy.edit.SimplifyByTangentSegments("C:/Data/Database.gdb/Parcels/Tax_Lines", '0.5 Feet')

Environments

This tool does not use any geoprocessing environments.
