Hey folks,
Last night I discovered that I can take a photo (I don't have a scanner), of an OS explorer map, overlay it on Google World then save it to my Garmin Oregon as a custom map. This works perfectly, to the point that my tracklog from Saturday's ride up Dumyat in Stirlingshire matches the custom map's summit!. I'm quite chuffed with this, but not totally as the resolution of the map is a bit blurry / naff.
Next, I tried capturing a screen shot from Multimap of the same area, overlaid it again and hey presto, it was a bit better. The resolution's still nowhere near as good as the OS maps that came with the unit on microSD card (OS Discoverer GB National Parks), though.
So I was wondering if you lot had any ideas? Is it simply a case of finding the optimal zoom? Or breaking each area up into lots of little cells?.....which might work, although could be time consuming...hmmmm 
Has anyone else had a go at this with good results? The accuracy seems great, I just want to optimise the clarity of the maps.
Cheers for any advice,
B.
