Validates the network topology of a trace network. Validation of the network topology is necessary after edits have been made to network attributes or the geometry of features in the network.
Inconsistencies between feature spatial edits and the network topology are marked with dirty areas.
The network topology must be enabled.
Invalid geometries encountered during the validate process will be included as error features in the Point Error and Line Error feature classes grouped under the trace network layer in the Contents pane.
The trace network for which the network topology will be validated.
|Trace Network; Trace Network Layer|
The geographical area for which to build the trace network. This parameter is similar to the Extent geoprocessing environment.
The validated trace network.
Build the network topology for the HydroNetwork trace network.
