It is good to have the technology in your phone, which some phones already have. The main problem is the PSAP must have inactive mapping software to say you are at the coordinates your GPS shows e.g. Main & Elm. Same principle applies to the OnStar system in GM vehicles. When you call 9-1-1 from a regular home phone the E-9-1-1 system is using a street map and your address to pinpoint your location. If your area is like mine, then your rural address probably changed from RR 5 Box # like mine to a coordinate system. This was required for both the postal service and E-9-1-1. Unfortunately some areas still have no 9-1-1. Imagine getting directions like "2 miles past the Thornton residence on Pine Valley Rd." Never mind the Thornton's moved in the 1970's. Occasionally on the ambulance service I volunteer for, we get directions just like that from a 9-1-1 call center. There are even times a caller calls and really has no idea where they are. You actually get calls to the PSAP like " I am on the freeway between Boise, ID and Pocatello, ID (a distance of 285 miles) and I just slid off the road because it's snowing. Then people wonder why my girlfriend (dispatcher) is soooo cranky. BTW these people think prepardness is just carrying the cell phone. I have spent countless hours searching for someone, only to have them found later at home, or not even in my response area.
