GPS Datum...??
Here's a question - I've got a couple of Garmin GPS units, a small GPSIII and a StreetPilot III. I'm off to Morocco soon and will take both, the SP3 for the trip down and the GPSIII for the waypoint guided routes.
I've finally figured out that the datum used in the GPS needs to be set for the units to work in concert with my OS Maps (I was struggling with building offsets into my co-ordinates!) but it made me wonder what datum would be needed to use in N. Africa.
Any thoughts??
Cheers
Greg
