Hmm I'll carry on recording my journeys this week then. They seem to
be almost always wrong, compared to Google Earth (or is this normal?)
and the ways already in the map (I haven't managed to get other
people's tracks yet, there was a 500 server error..... ). They do seem
to get better when in a wide road or an open area, e.g. in Hyde Park
my tracks are very accurate, almost to the metre probably.

Hopefully soon I'll be able to save the raw NMEA strings - at the
moment I'm using GEtrack (i'm not impressed with it......it should be
FOSS, it would get a lot better really quickly....) as it's the only
thing available that works on my N80 at present AFAIK (I'm new to
this).
