was a plank over wet ground where water flows so that walkers did not have to walk in it. This was the report in the note. Unfortunately, Streetcomplete photos are not saved when the note is resolved, so the link is broken. Where did you get that 1 cm from? I think the measuring stick is not working correctly ;) You can make it a bit longer, as far as I'm concerned.
