+EH Squared Posted March 18, 2002 Share Posted March 18, 2002 Isn't UTM the same no matter what datum? I thought UTM was a specific spot on the globe. Why should switching datum matter? I used the UTM conversion from the website, since that's how my Magellan was already set up. Man, was I waaaaay off. That's why I'm still scratching my head. I didn't think it would matter. BTW, the datum in my GPS was NAD27 and I switched it to WGS84. BTW, in order to calculate deviation in feet, do you have to have WAAS? Thanks, Eric Quote Link to comment
