Hi all,

As described, location:transition=yes may enable mappers to indicate

approximative ways (when guessing where a feature goes underground).

It would be great you spend a little time to write a feedback at the
bottom of the page.



Having read that page I don't really understand what the motivation for 
it is.  Maybe add a bit more information explaining how this new tag 
will provide information that isn't automatically apparent from other 
tags already present?  For example, if a road goes into a tunnel the bit 
not in a tunnel has no "tunnel" tag and the bit in the tunnel does; in 
that situation what extra information does a "location transition" provide?

Hi Martin

Can you provide an example for this situation please ?

I think about power=substation + substation=transition but several
different features can emerge from it and location:transition may indicate
where exactly in the given substation (which goes nowhere itself)

Cheers

It appears to me a bit like noexit=yes on a road, i.e. when the visible part
of the pipeline ends the tag would indicate that the pipe indeed goes 
underground,
and the osm-way does not end just because the mapper got tired or the hires 
aerial
turned lowres.

Can you provide an example for this situation please ?

I think about power=substation + substation=transition but several
different features can emerge from it and location:transition may indicate
where exactly in the given substation (which goes nowhere itself)

I think one example is with subway tunnel portals.

What about a pole where the cable continues both overhead and
underground ? This is a pretty common case in Belgium. The overhead
cables are on one side of the street and in order to connect the
houses on the other side of the road, the cable also continues under
the ground.

See e.g. [1], [2] where  [2] is a close up of the pole in front of the
house in [1]

Not exactly : to be really precise, the portal may be a man_made or
building feature and shouldn't get the location:transition tag.
The subway line way feature should (maybe this is was you thought about)
Nevertheless this example fits completely the current proposal

Just add location:transition=yes on the pole where the underground
cable gets connected to the overhead line.
The underground cable location changes to allow a connection overhead.

You can quick map utility wires and low voltage lines along road
according to this proposal of brycenesbitt (different tagging on
highway feature itself without any location:transition usage)

this is currently proposed to be used only on nodes, but might be useful for 
polygons as well.

Hi Clifford

The RFC was announced last august
