How can you verify it's the same stream?
I can't. I've deleted it.
This raises the question of the maximum length of a culvert under a
road, beyond which it is no longer permissible to map it as such.
Under a country lane is ok? But under a motorway?
This one is some 470 meters long. It goes under shopping and residential
areas, some roads and a train line, when (not if) it gets blocked it
floods the area.
Way: Terrys Creek (447098073)
Fortunately OSM has access to data of where it goes, in the past I would
think a straight line would have been used between the entry and exit
points.
The culvert is large ... say 3 meters height and 4 meters wide.
What is a stream? Even if it's the same water, does that make it the
same stream? Is a pipe a stream?
This one is a stream. It is well known in the area and thus easy to
verify from local knowledge, topology and the lack of any matching
features in the area.
And to my mind it is a culvert.
