Nearest Asset properties

Summary

The properties below are returned by the nearestAssets object when using Describe on a utility network.

If the filter nearest function is being used for a trace operation, these are the asset groups and asset types that will be returned.

Utility network nearest neighbor and nearest asset properties example (stand-alone script)

This stand-alone Python script prints a report of some utility network properties.
