I am at a loss. In words there are: natural stones from the local area, embedded into concrete. Picture:
I have tagged similar as surface=sett sett:shape=irregular, with an appropriate smoothness value
Sett was also my first idea, the additional shape attribute should make it clear to the next-comer that this is but an approximation.
Current markup there:
highway=path
sac_scale=hiking
scale:dav=red
trail_visibility=good
Why is the forum software asking me about ending a poll?
PS: I used that shape attribute. I did not bother to add smoothness to “steps”
