Remove Cutback Vertices (Topographic Production)

Resumen

Removes unwanted cutbacks from polyline and polygon features.

Cutbacks are high-angle turns that cause features to turn back toward themselves. These angles affect polyline and polygon features and can be caused during an editing session. For example, through a digitizing error, a river feature may have a short segment (less than one meter) that turns back toward itself and back in the original direction again.

Ilustración

Roads before and after running Remove Cutback Vertices with a 40 degree minimum angle are shown. One cutback remains because it touches another feature.

• If the angle formed by a vertex and its two neighboring points is smaller than the Minimum Angle parameter value, the vertex is a candidate for cutback removal.

• When the Skip vertices coincident between multiple features parameter is checked, the vertices that have angles smaller than the Minimum Angle parameter value will not be removed from the feature geometry if they touch another feature in the Input Features parameter value.

• If you performed edits on features in the map prior to running the tool, you can undo the results of the tool. If you haven't performed edits prior to running the tool, you cannot undo the results of the tool.

Cuadro de diálogo

Etiqueta	Explicación	Tipo de datos
Input Features	The polyline or polygon feature class from which cutback vertices will be removed. This feature class (or layer) will be modified.	Feature Layer
Minimum Angle	The minimum angle threshold value in degrees. The angle value should be within the range of 0–180. If the angle formed by a vertex and its two neighboring points is smaller than the specified minimum angle, the vertex is a candidate for cutback removal.	Double
Removal Method (Opcional)	Specifies whether cutbacks will be removed sequentially (individually) or all at once. Sequential—Cutbacks will be removed sequentially for a feature. After a cutback is removed, the change in geometry is considered when determining cutbacks to the remaining vertices of a feature. This is the default. All—Cutbacks will be removed for all vertices at once.	String
Skip vertices coincident between multiple features (Opcional)	Specifies whether cutback vertices will be removed when the vertex is snapped to another feature in the same feature class. Checked—Cutback vertices with angles less than the specified Minimum Angle value will not be removed from the feature geometry if they are snapped to other features. Unchecked—Cutback vertices will be removed without considering whether they are snapped to other features. This is the default.	Boolean

RemoveCutbackVertices example (stand-alone script)

The following stand-alone sample script demonstrates how to use the RemoveCutbackVertices function to ignore cutbacks that are snapped to a feature.

# Name: RemoveCutbackVertices_sample.py
# Description: Determines a cutback in a line or polygon based on a provided angle and repairs it.
# In this example, the tool will ignore any cutbacks that are snapped to a feature to avoid creating gaps.

# Import System Modules
import arcpy

# Check Out Extensions
arcpy.CheckOutExtension("Foundation")

# Set workspace
arcpy.env.workspace = r'C:\Data\Editing_Sample.gdb'

# Setting Local Variables
roads = r"Roads"
minimum_angle = "25"
removal_type = 'SEQUENTIAL'
skip_coincident_vertices = 'REMOVE_COINCIDENT'

# Execute Remove Cutback Vertices
arcpy.topographic.RemoveCutbackVertices(roads, minimum_angle, removal_type, skip_coincident_vertices)

# Check In Extensions
arcpy.CheckInExtension("Foundation")
