ArcGIS Data Reviewer checks

Available with Data Reviewer license.

Checks are tools that allow you to evaluate your data based on specific conditions. Some checks allow you to search for conditions, such as polygon slivers or cutbacks, while other checks allow you to search for features that have spatial relationships with each other. For example, you can find cutbacks on route features that impact measurement values in pipes or find buildings that have been mistakenly placed on water features.

The following tables describe the Data Reviewer checks that support constraint and validation workflows:

Attribute checks

Check name	Description	Workflow
Domain	Finds attribute values that do not comply with coded value or range domains that are associated with an attribute field	Validation
Query Attributes	Finds records based on a WHERE clause run against row attributes	Validation
Regular Expression	Finds features and rows that contain text values that do not match a defined pattern	Validation
Relationship	Finds rows in feature classes and stand-alone tables that violate cardinality or relationship rules defined in a relationship class	Validation
Subtype	Finds features in a subtype with improper or null attribute values	Validation
Table to Table Attribute	Finds features or rows that contain attribute values that meet a relationship you define and compares them to values in another feature class or stand-alone table	Validation
Unique Field Value	Finds rows in feature classes and stand-alone tables that contain nonunique values in an editable field or a list of fields	Validation

Event checks

Check name	Description	Workflow
Event on Event	Finds linear referenced events that overlay other events based on a relationship you define	Validation

Feature integrity checks

Check name	Description	Workflow
Check Geometry	Finds features whose geometry is empty, nothing, or not simple, as well as features with empty envelopes	Validation
Cutbacks	Finds segments where the angle between segments in a polygon or polyline is below a specified minimum value	Constraint
		Validation
Duplicate Vertex	Finds vertices from the same feature that are collocated or within a specified tolerance of one another	Constraint
		Validation
Evaluate Part Count	Finds features with a part count that is within a specified range of values	Constraint
		Validation
Evaluate Vertex Count	Finds polyline or polygon features that have a vertex count within a specified tolerance	Constraint
		Validation
Nonlinear Segment	Finds polyline or polygon features that contain nonlinear segments such as arcs and curves	Validation

Polygon checks

Check name	Description	Workflow
Evaluate Polygon Perimeter and Area	Finds polygon features based on the area or perimeter of the entire polygon or its individual parts or segments	Constraint
		Validation
Polygon Gap is Sliver	Finds gaps between polygon features that are below a specified thinness ratio	Validation
Polygon Overlap is Sliver	Finds overlaps between polygon features that are below a specified thinness ratio	Validation
Polygon Sliver	Finds polygon features with a thinness ratio below a specified threshold	Validation
Unclosed Polygon	Finds unclosed rings in polygon features	Validation
Unnecessary Polygon Boundaries	Finds polygon features that share a common boundary and contain identical attribute values	Validation

Polyline checks

Check name	Description	Workflow
Evaluate Polyline Length	Finds polyline segments, parts, or features that have a line length within a specified tolerance	Constraint
		Validation
Find Dangles	Finds polylines that have dangles within a specified tolerance	Validation
Find Disconnected Polylines	Finds polyline features that are not connected to other features in the same or other data sources	Validation
Monotonicity	Finds vertices in z-enabled or m-enabled polylines that are not strictly increasing or decreasing in value or are trending based on specified conditions	Constraint
		Validation
Polyline or Path Closes on Self	Finds paths or lines in polyline features that close themselves	Constraint
		Validation
Unnecessary Nodes	Finds polyline features that share a node and have matching attribute values	Validation

Spatial relationship checks

Check name	Description	Workflow
Composite	Finds features or rows based on the result from multiple Reviewer checks	Validation
Duplicate Feature	Finds features of the same geometry type that are collocated and share attributes	Validation
Evaluate Intersection Count	Finds polyline features that spatially intersect other polyline or polygon features a specified number of times	Validation
Feature on Feature	Finds features that have a specific relationship, either from two feature layers or within the same feature layer	Constraint
		Validation

Z-value checks

Check name	Description	Workflow
Adjacent Vertex Elevation Change	Finds features that contain an elevation (Z) change greater than a specified tolerance	Validation
Different Z at Intersection	Finds intersecting polyline features with z-value differences that are larger than a specified tolerance at intersection points	Validation
Evaluate Z Values	Finds features with z-values that fall within specified parameters	Validation
