Attribute Rules Overview

User defined rules for simple features using Arcade scripting

Ensure data quality during data collection and maintenance

Enforce data integrity

Defined in feature classes or tables

Supported across the ArcGIS system*

Ready To Use Rules

Pre-defined data validation methods

Easily configurable (no scripting required)

Support in Constraint and Validation workflows

Assess feature’s integrity, properties and spatial relationships

Automated reviewKey enhancements in ArcGIS Pro

• Attribute Rule integration

- Attribute (constraint) Rules enforce

data integrity during editing

- Reviewer checks assess a feature’s

- Integrity

- Spatial relationships

DomainFinds attribute values that do not comply with coded value or

range domains that are associated with an attribute field.

Query AttributesFinds features based on a query WHERE clause run against

row attributes.

CutbacksFinds segments where the angle between segments in a polygon or

polyline is below a specified minimum value.

Duplicate VertexFinds vertices from the same feature that are collocated or within a

specified tolerance of one another.

Feature on FeatureFinds features that have a specific relationship, either from two

different feature layers or within the same feature layer.

MonotonicitySearches Z or M-enabled polylines for vertices that are not strictly

increasing or decreasing in value or are trending based on specified

conditions.

Polyline or Path Closes on SelfFinds paths or lines in polyline features that close themselves.

Evaluate Polyline LengthFinds polyline segments, parts or features that have a line length

within a specified tolerance.

Evaluate Part CountFinds features with a part count that is within a specified value.

Evaluate Polygon Perimeter and AreaFinds polyline segments, parts, or features that have a line length

within a specified tolerance.

Evaluate Vertex CountFinds polyline or polygon features that have a vertex count within a

specified tolerance.
