Summary
The Evaluate Intersection Count check finds polyline features that spatially intersect other polyline or polygon features a specified number of times.
Overview
The Evaluate Intersection Count check finds polyline features that intersect the boundary of other polyline or polygon features a specified number of times. Features to compare can be from the same polyline data source or from a different polyline or polygon source.
An error is created for each input feature when it intersects another polyline or polygon feature the number of times specified in the rule.
Industry scenarios
In topographic mapping, linear features of the same type, such as railroads, that intersect more than two times may be an indication of intertwined features that you can merge or generalize. Other linear features include powerlines and water courses.
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 | No |
Yes | No | Yes (ArcGIS Pro 2.9 or later) | |
Syntax
| Parameter | Required | Description | Workflow |
|---|---|---|---|
Subtype | No | The subtype to which the rule is applied. | Validation |
Attribute | No | A query that identifies the features to which the rule is applied. | Validation |
Features to Compare | Yes | Input features are returned as errors based on their relationship to the features from this data source. Valid inputs are polyline and polygon features with a datum that matches the datum of the input features. | Validation |
Features to Compare Filter | No | A query that identifies the features to include in the rule. | Validation |
Number of Intersections | Yes | A query that defines the number of intersections that are not allowed between the input features and the features to compare. Any input feature with an intersection count that matches what is defined in this parameter is returned as an error.
Additional input is required if you choose an operator with upper and lower bounding values. | Validation |
Name | Yes | A unique name for the rule. This information is used to support data quality requirement traceability, automated reporting, and corrective workflows. | 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. | Validation |
Severity | Yes | 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. | Validation |
Notes
Keep the following in mind when using the check:
- Only polyline features are supported as an input data source.
- The data sources of the input features and Features to Compare parameter must share a common datum.
- When using z-enabled data sources, the z-value of a feature is not considered when evaluating for intersections.
- The Validation Status attribute value of both the input features and data sources included in the Features to Compare parameter are ignored during evaluation. For example, input features with a validation status of 0 (No calculation required, no validation required, no error), 1 (No calculation required, no validation required, has error(s)), 4 (Calculation required, no validation required, no error), or 5 (Calculation required, no validation required, has error(s)) are still included during rule evaluation.
- Include the data source for the Features to Compare parameter when sharing web layers with the Validation capability enabled.
- 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.
- Data sources for the Features to Compare parameter must include a global ID field.
