Summary
The Nonlinear Segment check finds features that contain nonlinear segments. This includes polyline or polygon features that contain curves and arcs.
Overview
The purpose of the Nonlinear Segment check is to identify polyline or polygon features that contain nonlinear segments. Nonlinear segments include those that contain circular or elliptic arcs and Bézier curves. Nonlinear segments can impact analysis and sharing workflows.
Industry scenarios
The following are example industry scenarios for the Nonlinear Segment check:
- In national and defense mapping workflows, features that contain nonlinear segments can impact feature generalization and sharing to non-Esri data formats.
- In roadway management, centerline features that contain nonlinear segments may result in the creation of nonmonotonic routes.
- In network datasets, curves or arcs without vertex coincidence to straight line vertices create an impact in network connectivity.
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:
| Validation | Constraint | ||
|---|---|---|---|
Reviewer batch job | Reviewer map rule | Attribute (validation) rule | No |
Yes | No | Yes | |
Syntax
| Parameter | Required | Explanation | Workflow |
|---|---|---|---|
Subtype | No | The subtype that the rule is applied to if the dataset has subtypes. | Validation |
Attribute | No | A query that identifies the features to which the rule is applied. | Validation |
| 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. | Validation |
| Description | No | Descriptive text of the error condition when noncompliant features are found. This information is used to provide guidance to facilitate corrective workflows. | Validation |
| 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 |
| 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. | Validation |
Notes
Consider the following when using the Nonlinear Segment check:
- Polyline and polygon feature layers are supported.
- The Attribute parameter is limited to comparison (=, <>, >, <, >=, <=) and logical (AND/OR, IN/NOT IN, LIKE/NOT LIKE, IS NULL) operators.
