@marscot: Nope, Hamilton New Zealand. But I've started marking Supermarkets and Fast Food places (big and easy to find from Yahoo's lowres pics) so if you ever come for a visit, you can find food!
@everyone else: I expect that as the GPS radios are coming from space, there's probably a fair few atmospherics and multipath and reflection that play with it. Indeed, I'm surprised it works at all. :)

Hi/thanks.
I have seen from my traces how accurate the unit is in general - most of the road lines are roughly where the road is; a systematic offset of 0-2m I can expect and fudge out; but what I'm thinking more of is the sudden unexplained leap 10 metres off to the side of the road - I don't recall twirling the wheel and driving through anyone's house! so it must be my cellphone/GPS thing. Probably it's getting a bad reading through interference or weak signal and so it's just doing the best it can with what it's got!
Solution is to move slower (walk!) and travel the same route multiple times to get more data points.

I started on JOSM and I think I prefer it to Potlach.. JOSM is offline and outside the browser; Potlach just irks me with their method of entering ways. I like/miss my right mouse button.

Alright, see you on the edit lists! :)
