Cutbacks

Available with Data Reviewer license.

Summary

The Cutbacks check finds polyline or polygon features that contain high-angle turns that cause features to turn back toward themselves.

Overview

The purpose of the Cutbacks check is to identify features that contain high-angle turns between vertices. These angles affect polyline and polygon features and can be created during editing and data conversion. Features that contain cutbacks impact length and perimeter calculations and analysis results.

When configured as a constraint rule, an error notification is returned upon creation or modification of a feature that contains one or more segments, where the angle between segments is below a specified minimum value.

When configured as a validation rule, line error geometries are returned for each segment where the angle between segments is below a specified minimum value.

Industry scenarios

The following examples highlight the impact that errors of this type represent:

  • In topographic mapping, elevation contours that contain cutbacks impact cartographic products, feature labeling, and generalization workflows.
  • In pipeline management, cutbacks on route features impact measurement values and the referencing of events along the route.

Input Layers

Yes

The input feature layers evaluated by the rule.

Valid inputs for this rule type are polyline and polygon feature layers. Click the Forward button Forward to apply filtering to specific features in the feature layer.

Reviewer rules

Subtype

No

If the dataset has subtypes, specify the subtype to which the rule will be applied.

Attribute rules

Minimum Angle Size

Yes

The minimum angle (in degrees) used to determine a cutback.

Features with an angle between segments below this value are returned as an error.

Reviewer rules

Triggers

Yes

The editing events that trigger the rule to take effect.

  • Insert—Triggers the rule when a new feature is added.
  • Update—Triggers the rule when a feature is updated.
  • Delete—Triggers the rule when a feature is deleted.

Title/Name

Yes

A unique title or name for the rule.

This information is used to support data quality requirement traceability, automated reporting, and corrective workflows.

Notes/Description

No

Descriptive text of the error condition when noncompliant features are found.

This information is used to provide guidance to facilitate corrective workflows.

Attribute rules

Severity

No

Severity of the error created when noncompliant features are found.

This value indicates the importance of the error relative to other errors. Values range from 1 to 5, with 1 being the highest priority and 5 being the lowest.

Tags

No

Tag property of the rule.

This information is used in rule authoring and management workflows to support traceability and reporting of data quality requirements.

Notes

  • When configuring filter parameters, care should be taken when using database-specific SQL functions that differ from those supported in your production environment. For more information, see SQL reference for query expressions used in ArcGIS.
  • Both polyline and polygon feature layers are supported with this check.
