README.TXT

If you can read this, you will have unzipped calfiles.zip

You should also be able to see a number of calibration files : .jpr, .map and .tfw

To use these with your GPS software you need to copy the files to the same directory as the map.

Depending on your software, you may need to open the map (.png) file or open the calibration file (e.g. .map)

If you rename the maps, you will need to edit the file name in the .jpr and .map files.

If you edit the maps - crop, rotate, rescale etc - the calibrations will no longer work correctly.
