Validate and fix geodatabase topology

Available with Standard or Advanced license.

On the Edit tab, in the Manage Edits group, Error Inspector Error Inspector shows validated topology errors in a table. It also contains tools to zoom to and fix errors using predefined fixes. The status of a topology, including errors and exceptions, is saved to the source geodatabase.

In the Contents pane, geodatabase topology rules appear as group layers. When you validate a topology, spatial relationships that violate the rule are identified and symbolized as errors on separate topology sublayers. Features that are subsequently edited and require validation are symbolized on the sublayer named modified area or dirty area or a similar name.

This topic provides a basic workflow for validating a geodatabase topology source rule in your map and fixing errors. To learn more about geodatabase topology rules and predefined fixes for a specific feature type, see the following topics:
