I'm interested in writing to the new Esri Utility Network.
I wonder if others are? What systems are you coming from? What is most important to you?
Maybe reading is more your thing? Vote and give feedback for reading the Esri Utility Network here.
Note: The reason for a new format is as a result of the Utility Network being completely Services-based. As such, the underlying Geodatabase is inaccessible apart from accessing it via the Feature Service.
