[mkgmap-dev] unpaved roads

Tue Feb 7 07:57:51 GMT 2017

But none are "paved" in the usual sense of that word. I would hate to drive
on a "fine gravel" road, or an ice road, unless I was prepared for it. Even
if the fine gravel were on top of a compacted substrate it would present a
hazard to bicycles and motorcycles. I'm not sure I care how a "salt" road
is classified - I've never seen one let alone driven on one.
