Re: [Tagging] Proposed definition for cycleways

2010-01-06 Thread Mike Harris
... I've refrained so far from getting into this burgeoning discussion thread 
... just 2 humble pleas though:
 
1. It is different in different countries. In England there are cycleways ... 
typically part of long-distance non-urban routes that have been created either 
primarily for cyclists or as shared routes for non-motorised users ... that 
don't have cycleway signs. But they are ALL available to pedestrians (and often 
equestrians) as well.
 
2. OSM is - I hope - not just a cycle project. Some of us walk from time to 
time (as well as cycle and drive). In England there are already many ways 
tagged as 'cycleways' - apart from dedicated cycle tracks alongside motor roads 
every one of these that I have seen so far is available equally to cyclists. 
pedestrians and (usually) equestrians. If we suddenly redefine 'cycleway' as 
being "exclusively" for cyclists there will be a s**tload of re-tagging to do!

think about how to express it more clearly. I'm not trying to turn OSM into a 
bike project - I'm actually just trying to work out a definition of cycleway 
that people can agree on and that is useful.




in Germany we have a very simple rule: if there is one of the signs (examples

it is a cycleway, if there's none of this, it is not. The rule is simple and 
easy to apply. Alternatively you can use path and additional tags (see wiki). I 
don't get your problem.

Btw: I do go by bike, almost everytime I go somewhere, and OSM is already a 
kind of bike project in some point of view, but as a cyclist it is still 
important to me if a way is a dedicated cycleway (different rules apply, e.g. 
you generally legally _have_ to take it by bike if you go where it goes, 
pedestrians can't take it), or not.

highway=path is the long-existing and equally long misunderstood

much (or twist it to mean 'totally narrow mountain hiking path with

No, a highway=footway, bicycle=designated is not the same as
highway=cycleway, foot=designated. If you just try to understand the
wiki definitions and not over-interpret them, you see that cycleway is
mainly/exclusively for bicycles where pedestrians might be allowed or
tolerated (depending of the country) and a footway is
mainly/exclusively for pedestrians where bicycles might be allowed or
tolerated.
These definitions feet well for countries where the
"mainly/exclusively" role is easy to determin which seems to be the
case in Europe. If it is not possible in Australia (or US), then
create you Australian:Map Features page like the 33 other countries
and write you own refinement of the tag definitions.

They can be replaced by a path + *=designated if you like but
deprecating the shorthands was massively rejected at the "path" key
creation.

I think "Germany" in this case has been used as a convenient placeholder for
"countries with cycleways like they have in Germany". But your point is well

Ok, so having created an entry for Australia (
http://wiki.openstreetmap.org/wiki/OSM_tags_for_routing/Access-Restrictions#Australia),
now does the above rule apply? That is, in Australia, according to the rules
I've written, is "highway=path, bicycle=designated, foot=designated"
equivalent to "highway=cycleway"?

I'll start a separate thread on the AU list where we can debate the access
restrictions.

It is an old page because designation and default access is an old
topic and there is no "black and white" answer. In some countries,
when you tag a cycleway, it is obviously not allowed for pedestrians
and contributors do not want to be forced to add a foot=no because in
some other countries it is "obviously" allowed. It's like asking the
whole world to add a bicycle=no with highway=motorway because it is
allowed in some US motorways.
It would be very helpful to see an Australian entry in this page, of course.

But isn't the point of the table to allow an Australian to tag
"highway=cycleway" and to mean something different from when a German does
it? And the point is that the makers of renderers and routers can use this
table? Presumably we should provide it in XML format or something to make
this easier.

Or is this the dream, but it's actually not used? What am I missing?

Jesus, what this dead horse has done to you?

Tag highway = cycleway for official cycleways and bicycle=yes if it's
allowed to have bicycles on footpaths somewhere. End of story. Yes, in
real life lot of people will use footpaths for cycling, and some
footpaths would be suitible for cycling, but will lack official
marking. Well, bad luck. We can't have everything as in real life on
OSM. We have to draw a line somewhere. In fact, if I see a footpath
who looks really supictious as usable for cycling too, I will note
this with note=* tag and maybe later I will check it out for sure. If
not, someone else propably will do.

Peter.

No, with 2xdesignated the way is equally dedicated to foot+bike.

With cycleway it is mainly for bike with foot tolerated, so cycleway is 
the equivalent of bike=designated, foot=yes.


But anyhow, it seems the monthly foot/bike/path discussion is on. So I'd 
invite you to check the point of views and discussions of previous 
instances and maybe contribute some to the summary page.

No it does not. This equality was originally intended in the path 
proposal, but there is also a large fraction of mappers who use it 
differently. Their argumentation is like this:
- "designated" means there is a sign
- in my country, when there is a sign, the way is exclusive for cycles
- cycleway means pedestrains are allowed, but if there is a sign, they 
are not, so it cannot be the same

Seems to me the wiki is inconsistent about how to treat
http://wiki.openstreetmap.org/wiki/Image:120px-Zeichen_240.svg.png and
http://wiki.openstreetmap.org/wiki/Image:120px-Zeichen_241.svg.png then.

http://wiki.openstreetmap.org/wiki/Tag:highway%3Dpath/Examples says that
such "A path designated for pedestrians and cyclists equally." can be tagged
as highway=cycleway, foot=designated OR highway=path, foot=designated,
bicycle=designated.  I assume, for the sake of logical consistency, that
highway=footway, bicycle=designated would also be allowed.

[Tagging] Proposed definition for cycleways

For all practical purposes, yes.

But to be exact, the meanings were defined only in the other direction:

a path with bicycle=designated can be considered equal to a cycleway
a path with foot=designated can be considered equal to a highway=footway

Since the older tags cycleway and footway were UK based, they (presumably) 
often had corresponding signs and knew well enough their surroundings
to choose between the two when there wasn't any sign present.

highway=cycleway tells nothing more than "it is signposted as a way for
cycling, or it is similar in construction to such ways nearby _and_
cycling is legal." Nothing of "bicycles are more welcome than
pedestrians".

highway=footway tells nothing more than "I may and can(*) walk there,
either it's signposted so or otherwise legal".

For drawing the map these were and are sufficient, given the knowledge
of default access restrictions and the guideline to "tag the highest
traffic category allowed, since if you can cycle on it, you can walk on
it, too" - except for the "bicycles only" ways.

*) Say, outside the city, I'm allowed to walk across the bogs (and it's
even open and level ground) but that doesn't make them a footway +
area=yes. Unsigned ways are either constructed for traffic, or wear
induced, which seems easy to spot and a suitable criteria when there's
no signage.

Just as a highway=path without any other tags tell nothing more than
"way where motor vehicles aren't allowed" but leaves everything else
to additional tags. With any =designated, a path turns into a something
descriptive ("Ah, it's for snowmobiles/bicycles").

When refining the definitions, I find that, given similar construction/ 
physical characteristics, a signposted shared use path (bikes and pedestrians 
"must use") is not significantly different from a light traffic way without any 
signs or with a "no motor vehicles" sign (both implying, at least in some 
countries, "bikes and pedestrians allowed"), to warrant being a distinct 
highway type.

All of them benefit from additional tags, most notably wheelchair=no,
surface=paved/unpaved/grass/mud ...

The rendering of original highway=cycleway should have been altered
before introducing highway=path, altered in a way to distinguish those
tagged additionally with a foot=no from all the others. But I guess no
one proposed that, nor did anyone mention that in the talk list, trac,
or in the wiki.

But all the points have been somewhat summarised here already:

So they should use access=no in addition to bicycle=designated.  Seems
simple enough to me.  This is also why access=official was created, even
though it’s redundant.

The mapper does not need to worry about them if the renderers just do
the right thing.  The shields are not really a property of the
highway.

I think so, but I don't think it's worth pursuing right now, as many
are still attached to the redundant cycleway/footway tags.

No, I'm trying to code up a proof of concept at present to parse the
wiki page and then after osm2pgsql runs, find any roads not tagged
with a shield and then add the shield information by using the road
information + polygon information.

So far I have been able to parse the wiki page, but I'm still working
on improving the lookup table the information is stored in so that
things happen as quickly as possible.

It probably doesn't help that I have no idea how to deal with reverse
regular expression lookups etc. :)

[Tagging] Love Hotel

2010-01-06 Thread Arlindo Pereira
Hi there,

5 months ago I started scratching a new tag amenity=love_hotel [1].
Since there was no recent activity, I think it's time to call your
attention one more time to it and start voting. What do you think of
it? The page explains itself (I think), but a love_hotel ("motel" in
Brazil, different from motel elsewhere) is a hotel where people go
exclusively to make love. The decorations, TV channels and so on are
very different from a regular hotel, hence a new tag (and not specific
sub-tags).

You want to parse the wiki page from within osm2pgsql?  I am not so sure
that's a good idea.  I think it should read that information from a
local file (which can be updated from the wiki by an independent tool).

Also, it would be nice if the mechanism is general enough that it can be
used elsewhere where the appearance of a way or node should depend on an
area it intersects or is within, like roads under buildings.

For all it matters, the raw wiki page could be cached locally and
parsed, however that isn't really isn't the issue, the issue is
turning the information on the wiki page (somehow) into a lookup table
to be used to assign shield symbols...

Well relations aren't ways, the ways go through/under/ buildings.

I like your request and I think this is useful in Brazil. Did you mean you
wanted to start voting?

I have heard of such in Tokyo as well.

Niagara Falls NY USA has motels that specialize in 'honeymoon
specials' which are rather similar but cater to longer stays and
actually presume as opposed to pretend their clientèle are married.

Motels in many commercial highway areas in the US have a reputation as
"No-Tell Motels" and are commonly used for assignations, as well as by
low budget commercial travelers, but are not quite so specially
equipped as the Brazilian, Tokyo, or Niagara Falls establishments
[based on reading their advertising at highway speed, haven't
inspected].

Heh, that makes about three people with very simple "takes" on the matter -
and they're all contradictory. The matter is "simple" to lots of people -
with different understandings each time.

Ultimately, it comes down to this: there is a clear difference between a
dirt path that bikes are allowed on, and a smooth, wide, obstacle free path
of compacted limestone that happens not to be signed with any bike signs.
That difference is worth encoding, and that's why "highway=footway
bicycle=yes" is not satisfactory to me at the moment, and why I'll continue
to (ab)use "highway=cycleway". My apologies for the dead horse though, I'm
happy to drop this at the moment, for want of anything more useful to add to
the conversation.

I do that when it's unpaved, and I really have no idea if bikes are even
allowed or not. One I did today: http://osm.org/go/uGtPRKFLD-

Ok. To be absolutely clear: in Australia "mainly for bike with foot
tolerated" does not exist. Also, "exclusively for bike" practically doesn't
exist. There is only:
1) Exclusively for pedestrians, and signed as such.
2) Generally for pedestrians, but you can probably ride a bike on it.
3) Designated for pedestrians and cyclists, with no particular priority.
4) (Rarely) Designated for cyclists exclusively, usually with a pedestrian
path nearby.
5) (And a few other cases involving horses and whatnot).

How would you encode this with default access restrictions?

Do they?  Did I miss something?  Last I know is that they are rendered
on top of buildings even if they are on a lower layer.

How is that rendering bug related to using relations to group ways?
