I thought you needed 3 points to get any kind of decent calibration.?ÿ I just use state plane coordinates and get a rough direction to look for the next corner and mostly use the distant from trying to stake the corner I just found.
I understand what Skeeter is doing with his calibrations. Imagine a figure with four sides, he puts 10000, 10000 on the NW corner and calculates coordinates for the other 4 corners, finds and locates the NW with a base on a here position nearby, then finds the SW corner, locates it, uses his calcs to calibrate to the two points, making the scale 1.0, holding the NW corner as his origin point. This will "rotate" his calibration onto the coordinates of the figure he calculated.?ÿThen he uses the calculated coordinates he did in the office to look for the other two. I'm pretty sure I have that correct.
You now have a calibrated file with an origin point of 10,000 10,000 and a lat long origin of whatever the NW corner turns out?ÿto be. I can't say what kind of projection the software created doing that, there would need to be some kind of rotation and scale factor applied to make it all work in a defined projection, obviously a?ÿscale of 1.0 wouldn't be it, so the software would need to come up with the correct one somehow.
