Duplicate geometry is when two features of the same geometry type are colocated, or are at the same location. The features can also share attributes and can be from two feature classes or the same feature class.
The Duplicate Geometry check searches a designated feature class for features that share the same geometry and are located in the same place. You can either search for all duplicate features or only those with identical attribution on editable fields. If you are validating attribution as well as geometry, you can optionally choose to ignore fields that are considered feature-level metadata. The check can be run on feature classes, subtypes, and features selected using a 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.
