Available with ArcGIS Pro Standard and Data Reviewer licenses.
The Unnecessary Nodes check finds polyline features that share a node and have matching attribute values.
ArcGIS Data Reviewer checks support multiple methods for implementing automated review of data. The following table identifies the supported implementation methods for this check:
Reviewer batch job
Attribute (validation) rule
(ArcGIS Pro 3.2 or later)
(ArcGIS Pro 2.7 and ArcGIS Enterprise 10.9 or later)
When polyline features contain pseudo nodes and identical attribution on editable fields, the shared node is often unnecessary. Pseudo nodes occur when the end node on a feature connects to another end node with no other nodes present. Features found with this check can be merged without a loss of information and can result in enhanced database performance.
The subtype to which the rule is applied.
A query that identifies the features to which the rule is applied.
Attributes to Ignore
The attribute values to ignore when evaluating for unnecessary nodes.
The attribute values to ignore during evaluation. Only editable fields can be ignored.
A unique name for the rule.
This information is used to support data quality requirement traceability, automated reporting, and corrective workflows.
A description of the error you define when a noncompliant feature is found.
This information is used to provide guidance to facilitate corrective workflows.
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.
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.
Keep the following in mind when using the check:
- M- and z-values are ignored when evaluating the geometry of input features.
- The Validation Status attribute value of input features is 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.
- The Attribute filter parameter is limited to comparison (=, <>, >, <, >=, <=) and logical (AND/OR, IN/NOT IN, LIKE/NOT LIKE, IS NULL) operators.
- The Attribute and the Attributes to Ignore filter parameters do not support the following field types: Big Integer, Date Only, Time Only, and Timestamp Offset.
