Reply to "GPS coordinates on maps"

While I agree, Mark, that we could require NAD83 or WGS 84, I think we should also require that the datum be indicated. This could catch the occasional device that is set to NAD 27, if someone has to check the datum for notation on the map.

Jim, it was all Greek to me when Neville, Tom & Pete Reigel, and Jay were discussing the effects of slow leaks on tires, and how that changes the accuracy of calibration, or whatever they were using long-hair math for. It put me to sleep a couple of nights.
