10308Re: Re: [Hammock Camping] GPS UTM coordinates
- Sep 1, 2005OK. Let me think about it. I have some stuff at home (I'm not there now
unfortunatly, but will be Fri afternoon.) I have some notes about UTM from
some old SAR stuff.
Most of the MiI I know uses MGRS (Military Grid Refernce System)so make sure
you have the same coords.
Off hand I would think that each box could be (should be) broken down into
10ths. Try dividing it out by ten.
I have some emails on it I can search now. BRB
