When mapping I sometimes come across ways without any tags, often along roads that have or have not been mapped already. Sometimes I use them as just another public track, sometimes I convert them into the road I believe is there, but I am not quite sure what is the preferred way to deal with them:
Is somebody in the middle of mapping something and I should leave the way alone?
Should the way be deleted, after the road, or whatever is there, has been mapped?
Should they be considered as reliable as uploaded GPS tracks?
