I am looking for some help and more detailed information about setting up custom elevation utility gp service in Portal 10.5.1 and 10.6. The documentation I've found thus far points me to a github page with a custom viewshed service. However, I am trying to figure out how this service is used once it's published to the federated server and entered as the value in Portal (which I've setup with a profile gp service). How do we use this utility service? Should it be visible somewhere for users connected to the Portal from Pro? Or visible in the Portal map viewer?
I may have received incorrect information but I had heard it's possible to re-point the "Ready-To-Use" elevation analysis tools in Pro to this custom elevation utility service. Is that true?
Any information would be much appreciated. Thank you!
