Nonlinear Segment

Disponible avec une licence Data Reviewer.

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 will be applied to if the dataset has subtypes.	Validation
Attribute	No	A query that identifies the features to which the rule will be 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.
• 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.
