Greg, >> But that is why I thought it didn't make sense. My understanding of GPS is that you fix your points from a series of measurements taken from sattelites. Thus, if point A and B somewhere on the earth, the distance between A and B are not relevant to the accuracy of the measurements! << That's my understanding as well. The distance between A and B isn't a _factor_ in GPS measuring. It's a _result_ of it. Figure the position of A, figure the position of B, then calculate the distance between 'em. Your calculated figure will differ from the actual figure obtained by traveling from A to B by 1mm (or less) per 96km of distance. Jon W.
