JOSM first and foremost since it's the only editor and validator that seems
to pay much attention to directionality. Other tools (trying to think of
the name of the tool right now and coming up blank that I'm thinking of
specifically) seem to validate cleanly if there's one continuous path end
to end, order and direction regardless (so a fairly broken relation would
still pass).

Re: [Talk-us] [Tagging] destination:street

[Duane Gearhart]

Hey Martijn,

It looks correct to me - using the destination:street allows users to know
if the ramp is branching onto the specified street name vs. heading toward
a street name - examples are located here:
http://wiki.openstreetmap.org/wiki/Exit_Info#Road_name_Example

Mappers have been using in the US too:
http://overpass-turbo.eu/s/ln4

Here is an example way:
https://www.openstreetmap.org/way/11502773#map=19/39.21853/-76.65894

You can see how it is used in the directions:

Regards,
Duane

[Talk-us] destination:street

[Martijn van Exel]

Hi all, 

The Telenav mapping team noticed quite a few destination:street tags on 
(mostly) motorway_link off-ramps in Canada. This is an undocumented sub-tag of 
the destination tag so I am curious how it is being used and if there is some 
sort of consensus that is documented somewhere else than the OSM wiki.

An Overpass query surfaced 1883 cases, http://overpass-turbo.eu/s/ln2  

Looking at a random one, http://www.openstreetmap.org/way/34154734 
 / 
http://openstreetcam.org/details/10767/4194 
 — I think in the US we would just 
map this as destination=Carman Road;Iriquois and destination:ref=1

So my question is whether this is some relic of a past practice, or is this 
actively used and encouraged mapping practice and if so, where should it be 
documented? 
(https://wiki.openstreetmap.org/wiki/Proposed_features/Destination_details 
 
seems to be a good candidate.)

We’re happy to help improve these tags based on OSC / Mapillary data but I 
wanted to make sure first that this is the way you all want to go.

Happy mapping,

Martijn van Exel

What tools were you thinking about? I remember submitting a patch to JOSM a 
while ago which did not get accepted.. That’s all I did on the tools end of 
things. Agreed support could be better.
