Hi, I am not from the area, but I did want to post my 2 cents about this issue. Your idea of how the offset got started sounds correct. I would caution you though that GPS traces can be offset, too, due to atmospheric effects. To really get a good trace with no offset you need to do a few traces on different days of the same road (or path is better since it is narrow) and through an area with few buildings around as these can cause offsets, too.
Other than those issues, if you trust your traces then I see no reason not to fix the offset, but as I said make sure your traces are good first. -AndrewBuck _______________________________________________ Talk-ca mailing list Talk-ca@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ca
