I'm a total newbie. I've tried to google this but have not found a solid answer. Essentially I am making a land navigation (orienteering) course and am using a trimble juno 3b with arcpad and arcmap 10. I am not making paper maps, ever. All I want to do is stand at a tree, make a point walk to another tree, make a point then tell other people to go X direction and X degrees. I can do all of this already on the GPS device and in ArcMap yet looking at the numbers I believe the degree's are off a little leading me to believe perhaps I am using the wrong coordinate system. Currently both the GPS and arcmap are using: GCS_WGS_1984 Datum: D_WGS_1984 Is this the correct coordinate system to use as a reference for a compass? Any help is greatly appreciated.
