Don't duplicate nodes or ways and don't join physical to non-physical.
Why not, and why not? Not to be rude, but it seems there are a few
different opinions around, so I think we give reasons for our
preferences.
Physical things can change (eg road or railway realignment), non
physical don't necessarily change. In the case of boundaries do we
definitely know that when a road is realigned does the boundary change
with it. This has been discussed many times since the import of the ABS
boundary data.
When I say just outside the two nodes can be immediately side by side
(infact touching), they do not need to be metres apart, so that there are
two distinct nodes.
So why is that a better solution than simply having the two ways
colinear? (Again, I'm not saying it's not...but please explain your
thinking.)
Rendering it appears to be the same line and therefore shows no
differently to a duplicated node/colinear way, even at the greatest zoom
level.
For editing (particularly for new users) it is easier to select which
one to edit (particularly in potlatch) and not try to select the correct
one using the appropriate keyboard shortcut which is not immediately
apparent.
Cheers
