An overview of the Topology toolset

The Topology toolset contains a set of tools that can be used to create and manage a geodatabase topology.

Geodatabase topologies help ensure data integrity. Using a topology provides a mechanism to perform integrity checks on data and helps validate and maintain better feature representations in a geodatabase. In addition, topologies can be used for modeling numerous spatial relationships between features. These enable support for a variety of analytic operations, such as finding adjacent features, working with coincident boundaries between features, and navigating along connected features.

Topology tools

Tool	Description
Add Feature Class To Topology	Adds a feature class to a topology.
Add Rule To Topology	Adds a new rule to a topology.
Create Topology	Creates a topology. The topology will not contain any feature classes or rules.
Export Topology Errors	Exports the errors from a geodatabase topology to the target geodatabase. All information associated with the errors and exceptions, such as the features referenced by the error or exception, are exported. Once they are exported, the feature classes can be accessed using any license level of ArcGIS. The feature classes can be used with the Select by Location dialog box or the Select Layer By Location tool and can be shared with other users who do not have access to the topology itself.
Remove Feature Class From Topology	Removes a feature class from a topology.
Remove Rule From Topology	Removes a rule from a topology.
Set Cluster Tolerance	Sets the cluster tolerance of a topology.
Validate Topology	Validates a geodatabase topology.
