Validate Network Topology (Utility Network Tools)

Summary

Validates features with dirty areas in the network topology of a utility network after edits have been made.

Usage

• Inconsistencies between feature spatial edits and the network topology are marked with dirty areas.

• When working with a utility network in an enterprise geodatabase, it is important to understand the validate operation is handled differently depending on the method used. The Validate command on the Utility Network tab uses synchronous processing, while the Validate Network Topology geoprocessing tool takes advantage of asynchronous processing.

  Dive in:

  The asynchronous validation process uses the UtilityNetworkTools geoprocessing service. The UtilityNetworkTools service is preconfigured in the System folder for feature services that include a utility network. It has a longer time-out setting and is reserved for utility network geoprocessing tasks.

• The network topology must be enabled.

• When working with an enterprise geodatabase, the input utility network must be a utility network service.

• When working with the Default version in an enterprise geodatabase, only a single session can run the validate operation at a time. While the validate operation is running, the network remains accessible for editing and tracing.

• When you validate a network topology based on a specific extent, the dirty areas that intersect the specified extent are clipped. To learn more, see Network topology.

• A trace is used during validate to discover which subnetworks were modified. The results from a validate operation return the name of any subnetwork that is marked as dirty along with its domain network and tier in the response. The output JSON for these Discovered Subnetworks values can be copied from the Message results in the details dialog box.

  • In situations where a subnetwork is dirty before the validate operation is run, the collection of discovered subnetworks will still contain the subnetworks modified by the validate operation.

  • When working with hierarchical networks, if all the subnetworks in a tier are dirty, the tier is not traced during the validate operation. When this scenario is encountered, dirty subnetworks in the tier are not returned in the collection.

• Failures may be encountered that prevent a validate operation from completing. When this occurs, use the Rebuild Network Topology tool to rebuild the network topology and repair inconsistencies. Rebuilding the topology within the extent ignores dirty areas and applies to all features in the specified extent.

Parameters

Label	Explanation	Data type
Input Utility Network	The utility network for which the network topology will be validated.	Utility Network; Utility Network Layer
Extent (Optional)	The geographical extent that will be used to validate the network topology. Current Display Extent —The extent will be based on the active map or scene. Draw Extent —The extent will be based on a rectangle drawn on the map or scene. Extent of a Layer —The extent will be based on an active map layer. Choose an available layer or use the Extent of data in all layers option. Each map layer has the following options: All Features —The extent of all features. Selected Features —The extent of the selected features. Visible Features —The extent of visible features. Browse —The extent will be based on a dataset. Intersection of Inputs —The extent will be the intersecting extent of all inputs. Union of Inputs —The extent will be the combined extent of all inputs. Clipboard —The extent can be copied to and from the clipboard. Copy Extent —Copies the extent and coordinate system to the clipboard. Paste Extent —Pastes the extent and coordinate system from the clipboard. If the clipboard does not include a coordinate system, the extent will use the map's coordinate system. Reset Extent —The extent will be reset to the default value. When coordinates are manually provided, the coordinates must be numeric values and in the active map's coordinate system. The map may use different display units than the provided coordinates. Use a negative value sign for south and west coordinates.	Extent
