Available with ArcGIS Pro Standard and Data Reviewer licenses.
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 on 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 data. The following table identifies the supported implementation methods for this check:
| Validation | Constraint | ||
|---|---|---|---|
Reviewer batch job | Attribute (validation) rule | Yes (ArcGIS Pro 2.4 or later) | |
Yes | Yes (ArcGIS Pro 2.5 or later) | ||
Note:
Map-based Reviewer rules are deprecated and are no longer available for use. It is recommended that you migrate automated review workflows to Data Reviewer capabilities available in attribute rules. Opening or saving a map document (.aprx) at ArcGIS Pro 3.0 removes all the existing map rules from the document.
Syntax
| Parameter | Required | Explanation | Workflow |
|---|---|---|---|
Subtype | No | The subtype to which the rule is applied. | Constraint |
Validation | |||
Attribute | No | A query that identifies the features to which the rule is applied. | Validation |
| 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. | Constraint |
Validation | |||
Triggers | Yes | The editing events that trigger the rule to take effect.
| Constraint |
| Name | Yes | A unique name for the rule. This information is used to support data quality requirement traceability, automated reporting, and corrective workflows. | Constraint |
Validation | |||
| Description | No | A description you define of the error when a noncompliant feature is found. This information is used to provide guidance to facilitate corrective workflows. | Constraint |
Validation | |||
| Severity | No | The severity of the error assigned when a noncompliant feature is 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 |
| Tags | No | The tag property of the rule. This information is used in rule authoring and management workflows to support traceability and reporting of data quality requirements. | Constraint |
Validation |
Notes
Keep the following in mind when using the check:
- Polyline and polygon feature layers are supported with this check.
- The Attribute filter parameter is limited to comparison (=, <>, >, <, >=, <=) and logical (AND/OR, IN/NOT IN, LIKE/NOT LIKE, IS NULL) operators.
