Feature on Feature

Mit der Data Reviewer-Lizenz verfügbar.

Summary

The Feature on Feature check finds features from the same or two different feature layers that share a spatial relationship and returns them as results.

Overview

The purpose of the Feature on Feature check is to find features that spatially relate to each other, such as a road on a land feature or a lake surrounded by grassland. Features from the same feature class can also overlap one another and share common attribute values.

When configured as a constraint rule, an error notification is returned when a feature that meets the conditions defined in the parameters of the rule is created or modified.

When configured as a validation rule, an error is created for each feature that meets the conditions defined in the parameters of the rule.

Industry scenarios

  • In parcel management, the Feature on Feature check ensures that lot units within tax parcels do not overlap each other.
  • In address management, road centerline features that contain overlaps or gaps in address ranges can impact the accuracy of locators used in geocoding.
  • In water utility management, features connected with different values on key attributes are a common problem. For example, errors may occur when a valve is connected to a pipe but the diameters of the pipes are different, such as a 12-inch diameter valve that connects to two 8-inch diameter water mains.
  • In electrical utility management, for proper network analysis, features that are connected must be located on the endpoints of another feature. For example, analysis errors may occur when a switch feature does not split the primary conductor line that it is connected to.

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:

Parameter Required DescriptionWorkflow

Input Feature Layers

Yes

The input feature layers evaluated by the rule.

Valid inputs for this rule type are point, polyline, and polygon feature layers. Click Filter or the Forward button Weiter to identify features used for comparison.

Validation (map rules)

Subtype

No

If the dataset has subtypes, specify the subtype to which the rule will be applied.

Constraint

Validation

Attribute

No

A query that identifies the features to which the rule will be applied.

Validation

Features to Compare

Yes

The features from Input Feature Layers will be returned as Reviewer results based on their relationship to the features from this data source.

Valid inputs for this rule type are point, polyline, and polygon feature layers. Click Filter or the Forward button Weiter to identify features used for comparison.

Constraint

Validation

Spatial Relationship

Yes

The spatial relationship to be evaluated.

  • Touches—A part of the feature comes into contact with the boundary of a feature from the Features to Compare source. The interiors of the features do not intersect.
  • Contains—A feature completely encloses a feature from the Features to Compare source.
  • Intersects—Any part of a feature comes into contact with any part of a feature from the Features to Compare source.
  • Within—A feature is completely within a feature from the Features to Compare source.
  • Crosses—The interior of a feature comes into contact with the interior or boundary (if a polygon) of a feature from the Features to Compare source.
  • Overlaps—The interior of a feature partly covers a feature from the Features to Compare source. Only features of the same geometry can be compared.

Constraint

Validation

Search Distance

No

A buffer distance used in determining the spatial relationship.

This parameter is only valid if the Spatial Relationship parameter is set to Intersects.

Constraint

Validation

Attribute Relationship

No

After the spatial relationship is evaluated, this option enables the comparison of attribute values to be included in the validation. For example, this option can be used to identify features that intersect and share a common attribute value.

Validation (map rules)

Invert Relationship

No

After the relationship is evaluated, this option determines if the result should be used as is or inverted. For example, this option can be used to identify features that do not intersect or are not within a defined distance of another feature.

  • Unchecked—The result of the validation will not be inverted. This is the default.
  • Checked—The result of the validation will be inverted.

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

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.

Constraint

Validation

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.

Constraint

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.

Notes

  • Input and comparison features must share a common datum to be compared.

  • When authoring a validation rule for multiple input feature layers, only fields that are common (matching name and data type) across all layers can be used in the Attribute Relationship parameter.
  • When this check is authored as an attribute (validation) rule, the Attribute parameter is limited to comparison (=, <>, >, <, >=, <=) and logical (AND/OR, IN/NOT IN, LIKE/NOT LIKE, IS NULL) operators.
  • When this check is authored as an attribute (validation) rule, caution should be taken to include the data source for the Features to Compare parameter when sharing web layers with the Validation capability enabled.
  • When configuring filter parameters for map-based rules, care should be taken when using database-specific SQL functions that differ from those supported in your product environment. For more information, see SQL reference for query expressions used in ArcGIS.
