New version of calibration applications: --------------------------------------- In addition to putting their results into the clipboard the new versions also print them onto the screen. New tool "Distance": -------------------- The tool calculates target positions with a known distance in east/west and north/south direction to an already known position. It may be useful if you have a map without useable geographic references. If you have at least one known position and if you have a distance ruler on the map you can define the ideal locations for calibration on the map and then enter their distance (either kilometers, nautical miles or statute miles) to the known position for getting their geographical position.
