I have put this diary note aside given the doubts about using Queensland official data sets. I guess you could call a map a data set.. I understand there is still work in hand to obtain the right licence from Qld Government.

Thanks, I updated the diary note. There are more C roads than I thought.

Appreciate your comments and it’s nice to know I’m not just doodling here for my own benefit. It motivated me to advance my half finished work. I thought such a classificaton issue would be small beer for the DWG but would welcome any other feedback. It would be good to have something incorporated in the Australian Tagging Guidelines/Roads as a result.
