If you want OSM Mapnik to render something differently you need to submit a

What about when a junction is a roundabout? Should that be rendered the

Following the general approach to handle  *=yes as kind of a fallback 
for cases where more detailled information is missing 
junction=crossroads in fact would add information.
Sure: There's not much reason to tag junction=yes anywhere as a fallback 
as these kinds of junctions are derived out of the fact of three or more 
streets (to distinct from the OSM way type) joining at a common node, 
but on the other hand one could (!) interpret that as the untagged 
default here.
junction=yes is therefore IMHO worse than junction=crossroads or 
junction=intersection.

junction=yield is no good because it does not specify which direction of
approach should yield.  junction=stop is also no good, for the same reason.

+0.5
junction=yield/stop is not enough, but better than nothing, and it would 
allow to search for nearby stop signs to determine that missing 
information perhaps.
Is there a good approach yet how to match stop signs to the intersection 
they belong to?
And if I'm at the street that has the right of way the software would 
have to look around at every intersection if there are stop or yield 
signs, as it's not obvious that there's a right of way (and not right 
before left or vice versa, which usually should be the default (at least 
in traffic, not necessarily in OSM), I think).


junction=stop/yield on the opposite would say: hey, here you 
definitively have to look about right of way signs around.

So, what I want is for Mapnik to render a label at a node if the there is a
junction=yes tag (and name=* tag) present.  This has been stated in the wiki

agreed (while I would prefer tagging junction=intersection nevertheless).

Well, first the question is if there are any roundabouts in Japan (I’ve 
never seen any, but that doesn’t mean that there are none). Second, for 
some other problems it would also be nice to go with a rendering 
according to region, meaning that the crossroads maybe are only 
displayed in Japan.
If we had something like that (Country specific rendering), we could 
tackle some other problems (the ugly fonts in Japan, for example).

Well, but this is now just something which came to my mind right now.

@Topic: I would also vote for junction=yes and name=* This seems to be 
the easiest. Basically, what we need is that the renderer understands 
that the name should be displayed in the box, right? So why not just go 
with junction=yes? This basically just does the job, right?

That is a very good question.

If we have a normal crossroads junction (or T) then there is a single node at 
the point where the two ways cross (or meet).

If we have a crossroads with dual carriageways then there are four nodes where 
the roads cross.

In Korea we also have named junctions at overpasses, so the junction name is 
where the two roads cross (or meet) but they physically don't join because 
one road is on a bridge over the other, and there are sliproads to move 
between them.

The first case is very easy.  The single node is tagged junction=yes, and 
name=*

The second case we could tag all four nodes.  Or put a single node in the 
middle, but then it's not obviously related to the junction.  Or put all four 
nodes in a relation.  Or draw a closed way (area) covering the junction.

In the third case we could tag the four nodes at the beginning of each slip 
road.  Or put the nodes in a relation.  Or draw a big area covering the 
entire junction.

Obviously the same applies T-junctions but there are only three nodes.

I could post this question on the talk-ko list and ask what Korean users would 
expect to see.

Unfortunately, I don't think anyone is using the data, so it's hard to know 
exactly what to do until someone uses it and says 'yes, this is great', 
or 'no, this won't do'.  Most of the junctions in Korea /are/ named as 
free-standing name nodes that were brought in in a big import a while ago.  
When I am mapping I usually cross-reference the name node with a photo of the 
sign from the junction and then merge the name node into the physical 
junction node.

Having written this, I think that a combination of single nodes where two ways 
cross, and relations where dual-carriageways cross or there is a bridge and 
slip roads would work well.

Best wishes,

Andrew

Ah, yes, I already do put the name of the junction on the motorway exit, but I 
have not noticed if this would apply to other named junctions (they are 
signed differently but conceptually they might be the same).  It would be 
simple enough to adopt this for lower classes of road.

One of the problems we have in Japan and Korea is that they already have 
awesome free maps online.  Much better than Google, with lots of features and 
resources, and everyone can use them to full effect on their smartphones.  
That in conjunction with satnavs in every car means that OSM has no purpose 
other than a pleasant hobby here, which I am very happy to continue.  One day 
someone will make use of it and release a killer app that everyone will want 
to use.

Actually, I was fixated on highway=traffic_signals and got carried away
in sort of hijacking the thread to mention its proper positioning while
losing the point of the discussion...

My position in regards to highway=junction vs. junction=* is neutral -
though I consider the everything=yes trend as namespace pollution. So :
- junction=* if there is enough diversity to justify that namespace
- highway=junction if junction=yes is going to represent most of the
junction=* space

I disagree.  This is too complicated.

The problem is to specify that a junction has a name, and to disambiguate 
these from any other junction.

Right now we have a mechanism for this when the junction is a roundabout:
junction=roundabout
name=*

In the wiki is was stated that named junctions can be marked with:
junction=yes
name=*

However, Mapnik does not render a label for this.  I'm not sure if any other 
renderer does.  Mapnik *does* render a label for a named roundabout.

To add a junction name we could just add a name=* tag to the junction node, 
but then there is no hint about what the name means.  So, by adding 
junction=yes it indicates that this *is* a junction, and the name is the name 
of the junction.  It's simple and obvious.

junction=crossroads would be fine, but it doesn't add any information.
junction=yield is no good because it does not specify which direction of 
approach should yield.  junction=stop is also no good, for the same reason.

So, what I want is for Mapnik to render a label at a node if the there is a 
junction=yes tag (and name=* tag) present.  This has been stated in the wiki 
for a long time.

Yes. Generally I think that non-Western map styles are completely 
neglected in OSM, but I have no idea to change that. How can we get in 
touch with the people who define the rendering styles? Somehow it seems 
to me (from the perspective of an ordinary user) that they are some kind

Well, this time I try not to give up until this is done :) It must be 
very frustating for Korean and Japanese users to map, but seeing that 
their efforts are basically completely useless on OSM, because the map 
will not display anything which is needed for a usable map in these areas.


Concerning tagging: I don’t think that there should be some special tag. 
The node which intersects both roads should just get a name property. 
JOSM displays the name there, and I think this is how it should be 
displayed on osm.org, too.

Take a look at this Google maps example from some small suburb of Tokyo:

http://goo.gl/maps/4j6c8

somehow in the middle you will see a a crossroad labelled 西原自然公園前 
(sorry, no English, this is read as “Nishihara Shizen Kōen Mae”). This 
is just it. The crossroad has a name which is displayed in the center of 
it. No direction or something like that.

Re: [OSM-talk] Display names of crossroads

2013-02-13 Thread Andrew Errington
Hi there,

My experience in Japan is that the junctions are named, but not oriented.  You 
give directions by saying 'go down this street and turn left at NAME 
junction'.  Or 'take the third right after NAME junction'.  Or if you are 
looking at a map, some junction names are shown, which makes it possible to 
follow a route by looking up for signs, and carefully counting the streets 
you pass.

The addressing system in Japan is not based on the crossroads name however.  
It's a block-based system.  The block has a name, and sub-blocks are 
numbered, and entrances are numbered around the edge of the block (I'm 
skipping a lot of detail[1]).

In Korea, again, junctions are not oriented.  Just named.  If you are driving, 
your satnav will announce the junction name that you are to take.  If you 
look out, you will see a sign with the name.  Again, with maps, the junction 
names are printed, which makes it easy to look around, see the signs, and 
locate yourself on the map.

The Korean address system used to be block-based, but now uses named streets 
with odd/even numbered houses on opposite sides of the road.

Best wishes,

Andrew

   This adress scheme is more important than street names in Japan, but
   currently, OSM does not display it. In consequence, it is very hard to

I don't think that's an appropriate way to name it.  It's not a locality, nor

+1
seems logical to use the junction-key for this together with name.
Maybe evaluating just yes would not be sufficient though, I imagine
there are also other (specific) types of junctions like
junction=roundabout.

The standard OSM.org map style is actually completely neglected, not just
for non-Western users. Several people have converted the style to CartoCSS
[1], which is much friendlier to edit.

Before talking about getting Japanese/Korean style features rendered on the
OSM.org standard map, someone should first demonstrate it is possible, but
making sure an appropriate tagging system is in place and creating a map
style. For this last part definitely look into TileMill, which can also
load the openstreetmap-carto style.

You could use something like junction=crossroads or junction=t, to 
specify what sort of junction it is.
Though this seems somewhat pointless, as the fact that its a crossroads 
or T-junction should be obvious from the geometry of the ways.


highway=junction would conflict with other highway tags. eg many 
T-junctions or crossroads are also tagged with highway=traffic_signals.

Named roundabouts is also ordinary : junction=roundabout + name=*

So junction=yes + name=* looks a bit strange but it's by far

Yes, actually the crossroads I tagged before all have traffic lights (I 
would even presume this is the more common case, because only the major 
crossroads have names, and they tend to have traffic lights - there may 
be exceptions, though).

Hi All,

We also have many cross-road or T-junctions junctions in the United Kingdom
that have names. Particularly in rural areas where early fingerpost signs
still exist:

Devon: I believe I am right in saying that the name on the column is the
junction name. I seem to remember that I've been provided driving
instructions such as turn left at xyz junction. Here's an example, but
they're easy to find if you zoom in on Google StreetView in a more rural
location you should stumble across them almost straight away.

http://www.geograph.org.uk/photo/2857741
http://www.flickr.com/photos/tollhouses/5904146435/in/photostream/

Dorset: Seems to put the junction name in the roundel at the top:

p.s. junction=* and name=* seems suitable to me (as we do with roundabouts)
