Hi Tim, a good benchmark is to see that if there are 2 or more GPX tracks on the road, and its more than 10meters off, then its a good reason to move it.
If you stopped a few times, it would be good to list what it was (gas stations, rest stops, food places, points of interest) the roads being imported are a mix of sources, with varring accuracy, and varring dates when data was origionally acquired. Hope that helps, cheers, Sam Vekemans Across Canada Trails On 8/28/09, Tim Francois <sk1pp...@yahoo.co.uk> wrote: > Hi all, > > I live in the UK, but parents live in Calgary.
