Hi Daniel, Thanks for the clarification. I was noticing as I browsed that data set that it was quite out of date. The Geobase data I found on MLI seems to have more "minor roads" such as driveways and approaches. I'm going to stick with the classifications in the Canvec data for the tertiaries. I'll probably downgrade single-lane unpaved tertiaries to unclassified though. I think there will likely be some tertiaries that are technically more minor roads, but you'd need to be a local to know that for sure. The farm road I showed as an example on Google street view is a prime example -- apparently this one is used by locals as a throughfare, and as such deserves the tertiary status, while one of the roads next to it that appears the same is not as well used. Go figure. :) Thanks, Tyler -- Tyler Gunn ty...@egunn.com _______________________________________________ Talk-ca mailing list Talk-ca@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ca
