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.
Overview
The purpose of the Evaluate Polygon Perimeter and Area check is to identify 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 upon the creation or modification of a feature based on the specified range defined in the rule.
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
- In facility mapping, certain types of structures, such as sheds, must have an area less than a specified size, otherwise they should 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.
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 | Reviewer map rule | Attribute (validation) rule | Yes (ArcGIS Pro 2.4 or later) |
Yes | No | Yes (ArcGIS Pro 2.5 or later) |
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.
| Constraint |
Validation | |||
Type | Yes | The method used when evaluating a feature's area or perimeter.
| 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.
Additional 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.
| 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 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
- The errors found by this check will 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 WGS-84 (WKID 4326).
- The Attribute filter parameter is limited to comparison (=, <>, >, <, >=, <=) and logical (AND/OR, IN/NOT IN, LIKE/NOT LIKE, IS NULL) operators.
