Anyone know about these? When I coded MGRS for Xastir I didn't know about MGRS-2 or MGRS-3. Perhaps the code needs to be updated to match the latest spec?

Sparke <[EMAIL PROTECTED]> Subject: Re: [CSAR] UTM vs USNG The shift from MGRS to MGRS-2 was they move the letter combos on us. The vertical letters (longitude equivalents) stayed the same, but the horizontal letters (latitdue equivalents) all shifted a bunch of letters (my area of NV switched from 11T LQ to 11T LE under MGRS-2). There is now a MGRS-3, but I haven't seen the difference from 2 yet. Why the change and whatever, haven't a clue. I just know the maps shown on the USNG site matched the letter sequence on the MGRS-2 screens rather than the older MGRS-1 I was used to and had maps for. My guess (and only a guess) was it was a change induced by the switch to WGS84 from NAD27. They wanted a bigger change in the system to make it more obvious when somebody was using the wrong one. As far as where I got the different MGRS's from, they just showed up on my Magellan GPS that I got about 3 years ago. First I knew there was more than one too.
