[Tagging] tunnel=culvert

Hi Colin,


good point, I agree that they don't share the node. So I guess the wiki

should be changed ?

Does the pipe have to be below the road? There could be another tunnel below the culvert as well.

In any case the pipe and the road are (in real life, and by design) not connected and if they share a node it will doubtless lead to all kinds of QA complaints.

Hi,

thanks for the feedback. I think tunnel=culvert is special,
my understanding is that it implies that the water goes through
some kind of pipe. So tunnel=culvert on a node
simply implies that the waterway is below the road,
no layer tag is needed.

Hello,

Now I noticed that the wiki also "allows" to use tunnel=culvert

On the other hand, the wiki "disallows" to use tunnel=* on a node.

but this is rarely used
(taginfo shows 945 tags on nodes and > 305.000 on ways)
I wonder why. The usage of a node seems to be clearer for me,
at least in those cases where the tunnel is almost as broad as the
road.

What would be in the tunnel? the waterway or the highway? how would
the layer= apply?

In my eyes it is the same case as with a
railway=level_crossing. We map it as a node (and only as a node).
Did I miss something?

In this case, the highway and the railway share the same level.
