Validate Network Topology (Utility Network)—ArcGIS Pro

Summary

Validates the network topology of a utility network after there have been edits to features in the network.

Inconsistencies between feature spatial edits and the network topology are marked with dirty areas.
When working with a multiuser model utility network, 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 timeout 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 an enterprise geodatabase, only a single session can execute the validate operation at a time in the default version.

ValidateNetworkTopology(in_utility_network, {extent})

Parameter	Explanation	Data Type
in_utility_network	The utility network for which the network topology will be validated.	Utility Network; Utility Network Layer
extent (Optional)	The geographical area for which to validate the network topology. This parameter is similar to the extent geoprocessing environment. Extent object—An Extent object can be used to define the extent. MINOF— The extent where all input features or rasters overlap (intersect one another).It is possible that none of the features overlap and that a null extent (zero width and height) may result. In such cases, no features or cells will be processed. MAXOF—The combined extent of all input data. All features or cells will be processed. Xmin, Ymin, XMax, YMax— Space-delimited coordinates that define the extent in the coordinate system where the input data is stored, for example, "-107.0 38.0 -104.0 40.0". pathname— Path to a dataset. The extent of the dataset will be used.	Extent

Parameter

Explanation

Data Type

in_utility_network

The utility network for which the network topology will be validated.

Utility Network; Utility Network Layer

extent

(Optional)

The geographical area for which to validate the network topology. This parameter is similar to the extent geoprocessing environment.

Extent object—An Extent object can be used to define the extent.
MINOF— The extent where all input features or rasters overlap (intersect one another).It is possible that none of the features overlap and that a null extent (zero width and height) may result. In such cases, no features or cells will be processed.
MAXOF—The combined extent of all input data. All features or cells will be processed.
Xmin, Ymin, XMax, YMax— Space-delimited coordinates that define the extent in the coordinate system where the input data is stored, for example, "-107.0 38.0 -104.0 40.0".
pathname— Path to a dataset. The extent of the dataset will be used.

Name	Explanation	Data Type
out_utility_network	The validated utility network.	Utility Network

ValidateNetworkTopology example (Python window)

Validate a network topology for the entire extent of a utility network named GridNetwork.

import arcpy
arcpy.ValidateNetworkTopology_un('GridNetwork', 'Default')

This tool does not use any geoprocessing environments.
