Unnecessary boundaries sometimes exist where adjacent polygons have the same editable field attribute values. In some instances, the two features should be merged into a single feature.
The Unnecessary Polygon Boundaries check finds polygon features within a single feature class that are adjacent to one another and have identical attribute values on editable fields. The designated feature class can optionally be a part of a database topology. Different algorithms are used to find unnecessary polygon boundaries for feature classes that have topology and those that do not. Optionally, fields that are considered feature-level metadata can be excluded from consideration. This check can be run on an entire feature class, a subtype, or a set of features that have been selected using an SQL query.
Once you have defined the criteria for the check, you can configure the notes and a severity rating. The notes allow you to provide a more specific description for the feature that has been written to the Reviewer table and are copied to the Notes field in the Reviewer table. The severity rating allows you to indicate how important the results from a check are in terms of your quality assurance/quality control processes. The lower the number, the greater the priority the check's results have.
