I knew someone at a 911 dispatch center in Georgia. They had someone calling about an intruder in their house, they’re hiding in a closet, etc, and gave the address. But! They had recently upgraded to e911 services, and they were able to see that the person was 5 miles from the address, in a different house, and asked them about that. They hung up after that. It was a college town, and they frequently got fake calls. It’s accurate enough that the dispatcher could see the person pacing in their actual location.
