map datums.

[sharpy]

can anyone tell me what map datum i would use if i were using an 'ordnance survey' style map in france ie; in the uk, i would buy an ordnance survey landranger map and my gps would show for example sy2234 3456. what would the french equivalent be; i could just use lat/long but really i am looking for something more 'local'.

many thanks,

Hi

Set your GPS to UTM WGS84

This setting  works with the blue grid squares on GPS compatible 1:25000 IGN maps. There are other coordinates on these maps and the addition of this grid system is fairly recent. It is nowhere near as well established as the  British grid system.

A good reason to buy new maps (if a reason is needed)
