Evaluate Polygon Perimeter and Area

Available with ArcGIS Pro Standard and Data Reviewer licenses.

Summary

The Evaluate Polygon Perimeter and Area check finds polygon features based on the area or perimeter of the entire polygon or its individual parts or segments.

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 and ArcGIS Enterprise 10.8 or later)

Overview

The Evaluate Polygon Perimeter and Area check identifies features that meet either area or perimeter conditions that are invalid. This can include an evaluation of the feature's entire geometry or its constituent parts or segments.

When configured as a constraint rule, an error notification is returned when a feature based on the specified range defined in the rule is created or modified.

When configured as a validation rule, an error is created during validation for each feature that contains an area or perimeter measurement within the specified range.

Industry scenarios

This check can be used in the following scenarios:

• In facility mapping, certain types of structures, such as sheds, must have an area less than a specified size; otherwise, they must be coded with a different structure type.
• In topographic mapping, features must have segment lengths greater than a specified value to maintain consistency in products generated from multiple data sources.

Syntax

Parameter	Required	Description	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
Evaluate	Yes	The geometric property of the feature evaluated by the check. Area—Evaluates the area of the entire feature or its individual parts Perimeter—Evaluates the length of the entire feature or its individual parts or segments	Constraint
			Validation
Type	Yes	The method used when evaluating a feature's area or perimeter. Polygons—Evaluates the area or perimeter of the entire polygon feature Parts—Evaluates the area or perimeter of individual parts of a polygon Segments—Evaluates the perimeter of the segments of a polygon	Constraint
			Validation
Search Goal	Yes	Error conditions evaluated by the rule. Any feature whose values match those defined in the rule are returned as an error. Is equal to—The perimeter or area is equal to the number of units specified. Is not equal to—The perimeter or area is not equal to the number of units specified. Is greater than—The perimeter or area is greater than the number of units specified. Is greater than or equal to—The perimeter or area is equal to or greater than the number of units specified. Is less than—The perimeter or area is less than the number of units specified. Is less than or equal to—The perimeter or area is equal to or less than the number of units specified. Is between (including bounds)—The perimeter or area is between or equal to the number of units specified in the lower bound (minimum) and upper bound (maximum) values. Is between (excluding bounds)—The perimeter or area is between the number of units specified in the lower bound (minimum) and upper bound (maximum) values. Is not between (including bounds)—The perimeter or area is not equal to or between the number of units specified in the lower bound (minimum) and upper bound (maximum) values. Is not between (excluding bounds)—The perimeter or area is equal to or not between the number of units specified in the lower bound (minimum) and upper bound (maximum) values. More input is required if you choose an operator with upper and lower bounding values.	Constraint
			Validation
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.	Constraint
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.	Constraint
			Validation
Description	No	A description of the error you define 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:

• The errors found by this check differ depending on whether the entire feature or its individual parts or segments are evaluated.
• When this check is authored as an attribute (constraint) rule, support for geographic coordinate system-based datasets is limited to those using Web Mercator (WKID 3857) or WGS84 (WKID 4326).
• The Attribute filter parameter is limited to comparison (=, <>, >, <, >=, <=) and logical (AND/OR, IN/NOT IN, LIKE/NOT LIKE, IS NULL) operators.
• The Attribute filter parameter does not support the following field types: Big Integer, Date Only, Time Only, and Timestamp Offset. If selected, the row header will turn red and will not allow the rule to save.
