John, Do they teach you that grid reference to give to first responders or do they determine it by address look up?
USNG seems like a good idea but appears to be a bit of a flop here because it is not used for general mapping and no one knows their USNG address. Well, I have mine written down somewhere, but I doubt 1% of families would know it, I can't find a road map marked in USNG (but topographical maps have either that or the underlying UTM grid), and I don't know if my town's first responders could understand USNG coordinates if I could recite them. One of my two GPS units will display it on request, however. ________________________________ From: John Frewen-Lord <[email protected]> To: U.S. Metric Association <[email protected]> Sent: Wed, December 30, 2009 1:50:17 PM Subject: [USMA:46331] Re: 144 years to go.... And Canada also uses a metric based grid for first responders. My house in Ontario not only had a street adress, but also a 6 figure grid reference, which emergency services would use to locate it.
