I’ve heard of similar AR type 3D real time mapping for utilities and construction, but i’m not sure what kind of capital, time and effort it would take to implement the new tech and train everyone to use it. We joke about it occasionally at my work place, but a lot of the field guys are old timers and they have a hard time getting used to using tablets for field work. Some day i hope though, i run across badly mapped stuff in GIS all the time.
