A staircase over the dunes first climbs to the top and then descends. How to tag incline and/or decline? asked 20 Jun '21, 21:02  Bart De Ruytter |
One Answer:
Map both parts as separate ways both pointing to the top then tag both with incline=up. answered 20 Jun '21, 21:23  TZorn |
You can even map the bit at the top as a footway (this may be of help to people who find climbing stairs hard work & need a bit of a rest at the top).
