I've added about a hundred more ways to the Fort McMurray area. I think road matcher was able to detect some more standalone roads once the surronding roads were imported, but it could be due to me using slightly different settings. I tried to manually make sure these didn't cause conflict with work people have done since (but I apologies if I missed a few overlaps) I also noticed that Road Matcher is not always able to match the geobase imported road in OSM to the source road in the NRN file.
