Hello SarahWard.
Did you have a look at the
http://www.basic4ppc.com/forum/tutor...-tutorial.html ?
There is already a chapter on 'Drawing on a scaled image' with an example program, not directly linked to GPS yet.

Wow! That would go way beyond normal GPS code. You'd need to be able to calibrate a map (which would be a heavy coding task). Then you'd need to be able to convert a point on the map into lat/long coords using the calibration data.

This exists in the
http://www.basic4ppc.com/forum/share...aled-maps.html program.
There will come an update of the Graphics Tutorial with a 'GPS Graphics' chapter in the near future.
Best regards.
