Cutbacks

Mit der Data Reviewer-Lizenz verfügbar.

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 in which the angle between segments is below a specified minimum value.

When configured as a validation rule, an error is created during validation when a feature contains segments in which 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.

Supported workflows

ArcGIS Data Reviewer checks support multiple methods for implementing automated review of your data. The following table identifies the supported implementation methods for this check:

No

A query that identifies the features to which the rule will be applied.

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.

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.

No

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

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

Constraint

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.

Validation

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

  • Polyline and polygon feature layers are supported with this check.
  • When this check is authored as an attribute (validation) rule, the Attribute and Features to Compare Filter parameters are limited to comparison (=, <>, >, <, >=, <=) and logical (AND/OR, IN/NOT IN, LIKE/NOT LIKE, IS NULL) operators.
  • When this check is authored as a map-based rule, care should be taken when configuring filter parameters using database-specific SQL functions that differ from those supported in your production environment.
