Hi, what can you do with this app? The program calculates parameters between screen and map (UTM) coordinates (min. 2 and max. 8 identical points). Easiest way is to use a UTM grid. These parameters can be used on a PPC to display e.g. the current GPS position or UTM coordinates. Notepad must be installed on your system. Copy your maps in the application folder. A “help file” is available in the software. Don’t hesitate to ask or criticize me!
