The correct topology of a utility network is the basis for managing information and maintaining connectivity between features. Therefore, all included features of a utility network must comply with the rules of the utility network.
Areas that have been edited or where changes have been made to the geometry of network features are marked as Dirty Areas and displayed in a separate layer. Dirty areas must be validated before being transferred to the dataset to ensure a correct network topology.
Detailed information about the network topology can be found in the Esri ArcGIS Pro Help.
Dirty Areas is a term from Esri terminology. Further information can be found on the Esri homepage.
Procedure
Validate Topology
1.Call function
The function can be activated from the Home tab or the Validate toolbar. The Validate topology tab opens in the left side panel.
Via the tab Validate topology the following functions are available for validating the network topology rules (e.g. correct snapping of objects):
a.Extent only: The network topology in the current map section is validated.
b.All: The entire network topology is checked.
The mode for the topology check can be selected via the action menu 
. The default setting is Standard. Further information on this can be found in the Esri documentation, chapter Validate Network Topology, parameter validationType.
Standard |
Perform a standard validation. |
Rebuild |
Rebuild and repair inconsistencies in the network index. |
Force rebuild |
Ignore any dirty areas and validate all features. Rebuild and repair inconsistencies in the network index. |
Depending on the size of the network, the check with the "Rebuild" and "Force rebuild" modes may take longer.
If the validation is successful because all topology rules have been recognized as correct, the area previously marked as Dirty Area is automatically removed from the layer.
If inconsistencies are detected during the validation, they are displayed in a list below the map window and the user must manually correct the features that led to this dirty area.
After a manual correction, the validation must be performed again. This iterative process of Validation - Correction - Validation must be executed until there is no Dirty Area left.
2.Evaluate result
The topological inconsistencies found during the validation are displayed in a list. With Change item grouping it is possible to switch to a view grouped by error type.
The following functions are available via the action menu :
|
Zoom to |
Zoom to the result(s) |

The visibility setting on the "Layer" tab affects the visibility of the results displayed here!
3.Show detail result
Clicking on a validation result will display further notes about the error and indicate possible actions to clean it up.
4.Filter results
The results displayed can be filtered by domain (e.g. electricity, gas, water) and error type (e.g. geometry, connectivity). Filtering affects the results list and the map.
