Evaluate Vertex Count

Mit der Data Reviewer-Lizenz verfügbar.

Summary

The Evaluate Vertex Count check finds polyline or polygon features that have a vertex count within a specified tolerance.

Overview

The purpose of the Evaluate Vertex Count check is to identify features that meet vertex count conditions that are considered to be invalid. For example, to improve system performance and reduce data storage requirements, it may be important to identify features that contain an excessive number of vertices.

When configured as a constraint rule, an error notification is returned when a feature with a vertex count specified in the rule is created or modified.

Syntax

Parameter Required DescriptionWorkflows

Subtype

No

The subtype that the rule will be applied to if the dataset has subtypes.

Attribute rules

Number of Vertices

Yes

The query that is applied to the vertex count of a feature. Any feature with a vertex count that matches what is defined in the rule is returned as an error.

  • Is equal to—The vertex count is equal to the specified value.
  • Is not equal—The vertex count is not equal to the specified value.
  • Is less than—The vertex count is less than the specified value.
  • Is less than or equal to—The vertex count is equal to or less than the specified value.
  • Is greater than—The vertex count is greater than the specified value.
  • Is greater than or equal to—The vertex count is equal to or greater than the specified value.
  • Is between (including bounds)—The vertex count is between or equal to the lower bound (minimum) and upper bound (maximum) values.
  • Is between (excluding bounds)—The vertex count is between the lower bound (minimum) and upper bound (maximum) values.
  • Is not between (including bounds)—The vertex count is not between or equal to the lower bound (minimum) and upper bound (maximum) values.
  • Is not between (excluding bounds)—The vertex count is not between the lower bound (minimum) and upper bound (maximum) values.

Additional input is required if you choose an operator with upper and lower bounding values.

Attribute 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.

Attribute rules

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.

Attribute rules

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

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.
