Here I diverge. If the hedgerow is an improtant part of the landscape
then I'd map it .. even if it is not at your required level of
'accuracy'. Reason: it is the relationship between the objects on the
map that is important rather than the absolute accuracy of any one
object.

How precise is the value of the length tag? From what is the value
derived?

A node does not have an orientation so why can it have a length?
If it has a length it does not make sense to use a node.

Some small features can actually be summarized as nodes when drawing their
shape sounds irrelevant regarding the cluttering it introduces.
I'm sorry that was trivial for me.
I won't draw a circle for a 5cm diameter pole
I understand your point.
Nevertheless, using a compass + indicating direction=* will be more precise
and exact than drawing the box according to aerial pictures (often
according where you think the box is)
Same for length=* or any other physical properties.

I have noticed a length tag used on some linear ways [1]. It seems
that this is redundant, as the length could be calculated from the

On a node it makes perfect sense. At least as long as it is not
Just FYI, at OSM-PL people map highway milestones - as nodes near
highways - which is less prone to error due to people editing
geometry..

In my mind, a road climbing a mountain won't have the same length in
reality than in the DB : the Z dimension may have influence too.
I just did a quick search in iD. We display the “Length” field only on the
Runway preset.
(I think it does make sense there)
Thanks, Bryan

Agree, length makes sense on nodes
