Subtype

Disponible avec une licence Data Reviewer.

Summary

The Subtype check finds features with improper or null subtype values.

Overview

The purpose of the Subtype check is to find features that contain attribute values that are not defined for the subtype. This includes attribute values that are inconsistent with the subtype's defined values and may optionally include null attribute values.

Subtypes are a subset of features in a feature layer. For example, features in the Bridge line layer can be organized into separate subtypes for bridges, overpasses, and viaducts instead of combining them into one subtype. However, if the product specification does not allow this type of granularity between feature types, these subtypes would be considered invalid.

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:

Search for Null Values

Yes

Indicates whether the check searches for null subtype values.

Notes

No

Descriptive text of the error condition when noncompliant features are found.

This information is used to provide guidance to facilitate corrective workflows.

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.

Notes

  • Domain-restricted attributes for features or table records assigned to an invalid subtype can't be evaluated when using the Domain check. Evaluation of domain-restricted attributes will be required once subtype-related errors are corrected.
  • When this check is authored as a map-based rule, care should be taken when configuring filter parameters using database-specific SQL functions that differ from those supported in your production environment.
