This tuto is based on the 'N-point calibration', which I think is the most versatile:
We add points which we know the coordinates and position on the picture (cities, road intersection,… etc.).
In this example, I made a quick calibration with 3 points, the coordinates of which were found with the help of Google Earth.
Caution to be accurate and choosing points at the ends of the map!
Do File / Export - Calibration.
Check OziExplorer then Export.
Copy on your PDA, the picture and le .map file generated.
On NoniGPSPlot :
Main menu, Advanced setup, Maps, New, Import, and select the .map file.
It will probably be necessary to re-définir the File (the path on your PC will probably not the one on your PDA).
Remark : The picture .ozf2 are not recognized.
Remark : It is possible that NoniGPS ask the UTM Zone: Under CarteSurTable, select Grid UTM/UPS, Datum WGS 84. look at the Zone then Cancel.
