Re: [Tagging] improve tagging of traffic_calming

2015-11-22 Thread Gerd Petermann
Hi Chris,

I am not a member of talk-GB, could you please post a link to this
discussion and ask the mappers to review the remaining 
highway=traffic_calming nodes in GB?

thanks,
Gerd

I asked Gerd to revert the edit simply because it was an undiscussed
mechanical edit, for which Gerd has acknowledged and apologised (thanks
Gerd). I would like to add that discussion on this list may reach a
conclusion about the tags used (if we're lucky), but that still will not
be a suitable place to discuss a mechanical edit. Gerd's link is to an
edit across much of GB, so it needs to be discussed *and* agreed with GB
mappers. I would suggest that GB mechanical edits need to be discussed
on talk-GB and / or the #osm-gb irc channel. Similar mechanical edits in
other countries or areas need to be similarly discussed and agreed in
appropriate lists and channels too.

[Tagging] Relevance or otherwise of the wiki (was: improve tagging of traffic_calming)

It doesn't surprise me that something documented with certainty in the 
wiki simply doesn't describe what mappers actually do.  For example, I 
noticed the https://wiki.openstreetmap.org/wiki/Key:healthcare page only 
very recently** - someone who expects the wiki to document how other 
mappers tag things might think from reading that that they should use 
e.g. "healthcare=dentist" instead of "amenity=dentist", which not borne 
out by actual usage figures (there are 30k amenity=dentist and <900 
healthcare=dentist).


We (all mappers, not just new ones) simply can't rely on the wiki for 
"how to map X" until this sort of "creative wiki editing" is more under 
control*.


Cheers,

Andy (SomeoneElse)

I think in the case of traffic_calming 
http://wiki.openstreetmap.org/wiki/Key:traffic_calming
the current wiki describes exactly what most 
mappers do, that's why I asked the question you cited.
I think the only missing point is the explicit hint that 
highway=traffic_calming should NOT be used and 
removed when found similar to the hint for ford
http://wiki.openstreetmap.org/wiki/Key:ford#Deprecated_Tags

[Tagging] highway=crossing not rendered on Mapnik (& others)

2015-11-22 Thread Dave F.

Hi

Before listing this as a request on the openstreetmap-carto I thought 
I'd check/discuss here first.


From the wiki http://wiki.openstreetmap.org/wiki/Key:crossing & the 
default selection of the 3 main editors, the tags for a pedestrian road 
crossing that's separate from other traffic control lights are:

highway=crossing
crossing=*.

This combination doesn't render in Mapnik. It's led many people to 
(possibly inadvertently) tagging for the renderer:

highway=traffic_signals
crossing=*

Is there a reason why it's not in mapnik? It's doesn't cover up other 
entities as can be seen as used in the latter tag configuration.


Also, on the wiki under traffic_signals 'crossing=traffic_signals' it 
says "Mostly near highway=traffic_signals." Unsure what's meant by that. 
If the pedestrian crossing is separate they are almost certainly not 
near traffic signals. I think it should be clarified or removed.


Cheers
Dave F.

You may or may not know, but mid-block signalled crossings are a bit of a
UK-specific phenomenon. In many other countries (in Europe, anyway),
signalled crossings are part of junctions.

Anyway, if you want something rendered, raise a ticket with the renderers;
it's not a tagging issue as such.

Great Scott. Just searched the previous messages & find I asked posted 
the same point just a few months back, so please ignore this if you 
wish, although i still think it needs clearing up if only to prevent 
incorrect tagging & improving the map (IMO).

I would not say so, I know a lot in Germany. Often they are on-demand.
There are also plenty cases when there is a signalled crossing on a
tertiary road near a junction with a residential, and the traffic light
only regulates the pedestrian flow across the tertiary, while the
motor traffic coming from the residential into the tertiary is
unregulated.

+1

They are rare in California (IMO), but there are some here in Japan. In the 
discussion with Signal labels, one of Tomoya's examples of "junction names" was 
a pedestrian crossing controlled by a signal. 

However, we also have a decent amount of plain zebra crossings mid-block (so 
not near an intersection) with no traffic control too.
