Re: [Tagging] Synonymous values in the shop key

2014-08-14 Thread Mateusz Konieczny
To summarize (for the second time):

shop=fish, shop=fishmonger and shop=seafood are not synonyms as fish may
also apply to pet fish and seafood is not covering freshwater fish
shop=winery, shop=wine (shop=wine is a wine seller, where shop=winery is a
winer maker selling his own production)
shop=delicatessen, shop=deli I am not understanding difference but there is
some
shop=jewellery (139) - shop=jewelry (13299, documented) (there is a
planned change in the opposite direction)

There were no objections to following changes:
shop=bags (201) - shop=bag (409, documented)
shop=antique (110) - shop=antiques (1394, documented)
shop=pets (162) - shop=pet (5393, documented)
shop=pharmacy (1591) - amenity=pharmacy (115759, documented)
shop=ice_cream (710, documented but difference between using amenity and
shop keys is not documented) - amenity=ice_cream (4053)

 Actually, we discussed a suggestion to change this in the other
 direction while this thread was running. Although it was in a separate
 thread, I think that discussion counts as an objection.

amenity=ice_cream sounds very strange to me. I can't imagine a lot of
people actually coming up with that themselves - can it be a mass edit
or an editor preset gone wrong?

I mean, the amenity consists not in there being ice cream, but there
being a place where you can get ice cream.

That would like tagging amenity=bed for a hotel or amenity=food for a
restaurant...

Seems good to me.
In the same vein (enjoy the pun), you might add tags for waterways that
flow through a cave.
Especially if a touristic visit includes a trip on barges.

 A *tunnel* https://en.wikipedia.org/wiki/Tunnel is an underground or
 underwater passageway, enclosed except for entrance and exit, commonly
 at each end.

 *tunnel* http://wiki.openstreetmap.org/wiki/Tunnel=* is used for
 roads, railway line, canals etc that run underground (in tunnel

Neither OSM wiki nor Wikipedia restricts it this way. There is even section

As a native speaker I may as well chip in, and say I have no problem
at all with tunnel referring to a natural tunnel as part of a cave
system.

Well, no-one ever supports new tagging, the question is if it's

Since payment:bitcoin=yes is a de facto and used tag and since 
payment:website:bitcoin=yes is not, I would suggest a combined usage of 
payment:bitcoin=yes and payment:website:bitcoin=yes until the new tag is 
chosen by more mappers for their use cases. I'm considering using the

It was not about accessibility but about fact that highway=footway is
accessible
for pedestrians (in this case typical tourist) and highway=path may be
nearly
anything, depending on additional tags (in this case it is accessible only
for
more experienced speleologists).

But it is probably overly subtle and useless distinction (like natural=wood
and
landuse=forest) clear only for small amount of people and therefore it is
good that
it is gone.


 No, they do not fit. Caves are complex three-dimenional structures. In most
 caves there are no paths. You go or climb or rope down whereever you feel

Probably my bias, caves that I know (Kraków-Częstochowa Upland) may be well
represented using ways. But at the very least it is possible to represent
footways
designated for inexperienced tourists, especially in show caves.

This is the same as with a pedestrian square - there's no specific

to make them part of the OSM database, both for showing their
existence and to help with various routing applications.

It's great that these specialist databases exist! But as I imply

in OSM. We can be happy to do this, without attempting the level of
detail in the specialist databases.

 I wonder about adding something that would denote that way is part of cave,
 maybe natural=cave_tunnel?

 See above. A tunnel is not a cave. If you want to express that a way is
 underground, use layer=-1.

I'm afraid layer=-1 does not express that a feature is underground. It
expresses that a feature is lower than all features at layer=0+, but
there's no guaranteed relationship with ground level. There are quite
a few objects with the implicit layer=0 but which are not at ground
level (e.g. tunnel=culvert items: http://overpass-turbo.eu/s/4zE).

cave=* is not defined.
I know I still have to learn that OSM is fuzzy, but using cave=yes for

This said, we could wait for years for a rendering of cave=yes, let
alone routing support.
Rendering and routing don't care if it's man-made or not. They just work

Why not use the well established tunnel=yes and layer=-n?  And cope with

One question.
How would people map a cave?
As far as I know, GPSes don't really work underground, and obviously there
is no sattelite imagery for them.
I imagine that's why there is no scheme right now.

I am not sure about English terminology. In German, we call natural cavities
Höhlen (caves), and artificial cavities Stollen (adits?). A straight
Stollen with an entrance on each end is a Tunnel (tunnel). I think that
the meaning of the English word tunnel is just the same as in German. In
that case, tunnels and caves are mutually exclusive.

Not in my native opinion, but let's see what other natives think too.


Sometimes I think that it's a real shame that OSM didn't start in 
Germany - it'd much easier to be _precise_ about some things.


The word adit is rarely if ever used in common parlance - locally to 
me (Derbyshire, England) it's usually used to describe mineworking 
drainage tunnels.  Wikipedia (1) suggests a more general use for 
horizontal shafts (for e.g. into a drift mine) but I'm not familiar with 
that usage (and there are many mineworkings very local to me, including 
one major former drift mine).  It certainly doesn't refer to all 
artificial cavities.


It's also worth bearing in mind that whatever word you use there isn't a 
simple distinction between natural and artificial caverns - many 
early mineworkings were extensions of natural cave systems (and cavers 
also sometimes extend natural systems to connect them and allow 
further exploration).

Andy

Re: [Tagging] Bitcoin: Distinction of purchase through website and cash register/Point of sale

2014-08-14 Thread Serge Wroclawski
Anita,

Frankly a large majority of the bitcoin edits are unauthorized (and
probably copyright violating) imports. Discussions of website allowing
bitcoin seem to fall in that same category. There have been few
complaints but I think it's inevitable that if the imports continue,
someone will complain and the DWG would be asked to step in.

So I'd say unless you visit a store and know for sure they take
bitcoin there, leave it out.

routing was obviously a free bonus, but please notice that you don't

You don't even need to enter the cave if all you want is measure the

One option is the same way that people mapped before GPSs arrived - 
accurately measure a baseline and triangulate from it.  Obviously it's 
substantially harder to do in a confined space with low light than 
elsewhere.

payment:bitcoin=yes is a de facto tag for a store that accepts Bitcoin 
AT THE POINT OF SALE, like all other payment=* tags. What you do is 
redefine its meaning to it in some way accepts Bitcoin somewhere.


payment:website:bitcoin=yes on its own is fine. 
payment:website:bitcoin=only would probably be even better for this purpose.



I'm considering using the
combination for the moment so that backwards compatibility is maintained.


Except that that combination is not backward compatibile as explained 
above. And you don't even solve the problem, that a map displaying 
payment:bitcoin=yes might not actually accept it at the point of sale.



Since payment:bitcoin=yes is a de facto and used tag and since
payment:website:bitcoin=yes is not, I would suggest a combined usage of
payment:bitcoin=yes and payment:website:bitcoin=yes until the new tag is
chosen by more mappers for their use cases. I'm considering using the

I'd fully agree with that.  Most of the bitcoin taggers seem just to

seem interested in recording anything other than the magic word

Ok, I exaggerated with the word obviously. But tunnels are used a lot in
OSM and they have gotten a very clear semantic meaning: a man made opening
in the ground. There's no reason to add caves to that definition.

The reason renderers don't render it is invalid because of one of the
oldest rules in OSM: don't tag for the renderer.

And if a data consumer tries to find the length of all footpaths in tunnels
in Poland, she will ask find all highway=footpath + tunnel=yes, and she
will find all tunnels plus all caves. And that isn't right.

I suggest starting the cave=yes tag, and we'll see, maybe the renderers
will pick it up. They only have to treat it the same as tunnel=yes.

In general, it's also a lot easier for applications to treat two tags

This would be applicable after defining tunnels as man made (in case that

I agree on the general strategy, but in this case I don't think cave=yes
would work fine by itself as these are underground ways that require to
be interpreted as being underground.
With that it is required to interpret the new tag to handle these ways
in a useful way. Using tunnel=cave would make that easier as a fallback
to tunnel=yes creates useful results. This fallback does not
differentiate between cages and other tunnels, but it differentiates
cage tunnels from ways above ground.

Pedestrian squares are 2-dimensional. Caves are 3-dimensional. Many cave

Forget routing in caves. There's no GPS. And those who get lost without
routing apps will get lost in a cave anyway.

 I'm afraid layer=-1 does not express that a feature is underground. It
 expresses that a feature is lower than all features at layer=0+, but
 there's no guaranteed relationship with ground level.

In central Europe it is, but habits may vary around the word. Much chaos
these days...

In my opinion, there is some misconception by people who are used to image
editing software such as Photoshop, Adobe illustrator, Gimp, Corel Draw,
Inkscape, etc., as well as CAD software. In all of these applications,
layers stand for rendering order. In OSM we need to think in physical layers.

Caves are just an example. There are many more underground objects which are
not tunnels. E.g. I used to go to school over a landfill for 8 years without
knowing, because it was covered with soil and grass. The only way for
renderers to know is by eveluating the layer tag. Of course you could set
some additional tag like underground=yes, but having two concurrent tags for
the same thing is just a mess. You'll soon get a lot of inconsistencies.

 There are quite
 a few objects with the implicit layer=0 but which are not at ground
 level (e.g. tunnel=culvert items: http://overpass-turbo.eu/s/4zE).

Therefore we need to tag them all with layer0. There was a proposal for
implicit default layer=1 for bridges and -1 for tunnels, but unfortunately
it was voted down, so we are damned to set it manually every time.

 routing apps will get lost in a cave anyway.

  I'm afraid layer=-1 does not express that a feature is underground. It
  expresses that a feature is lower than all features at layer=0+, but
  there's no guaranteed relationship with ground level.

 In central Europe it is, but habits may vary around the word. Much chaos
 these days...

 In my opinion, there is some misconception by people who are used to image
 editing software such as Photoshop, Adobe illustrator, Gimp, Corel Draw,
 Inkscape, etc., as well as CAD software. In all of these applications,
 layers stand for rendering order. In OSM we need to think in physical
 layers.

 Caves are just an example. There are many more underground objects which
 are
 not tunnels. E.g. I used to go to school over a landfill for 8 years
 without
 knowing, because it was covered with soil and grass. The only way for
 renderers to know is by eveluating the layer tag. Of course you could set
 some additional tag like underground=yes, but having two concurrent tags
 for
 the same thing is just a mess. You'll soon get a lot of inconsistencies.

  There are quite
  a few objects with the implicit layer=0 but which are not at ground
  level (e.g. tunnel=culvert items: http://overpass-turbo.eu/s/4zE).

 Therefore we need to tag them all with layer0. There was a proposal for
 implicit default layer=1 for bridges and -1 for tunnels, but unfortunately
 it was voted down, so we are damned to set it manually every time.

 I am not sure about English terminology. In German, we call natural cavities
 Höhlen (caves), and artificial cavities Stollen (adits?). A straight
 Stollen with an entrance on each end is a Tunnel (tunnel). I think that
 the meaning of the English word tunnel is just the same as in German. In
 that case, tunnels and caves are mutually exclusive.
 Not in my native opinion, but let's see what other natives think too.
 
 Sometimes I think that it's a real shame that OSM didn't start in Germany - 
 it'd much easier to be _precise_ about some things.
 
 The word adit is rarely if ever used in common parlance - locally to me 
 (Derbyshire, England) it's usually used to describe mineworking drainage 
 tunnels.  Wikipedia (1) suggests a more general use for horizontal shafts 
 (for e.g. into a drift mine) but I'm not familiar with that usage (and there 
 are many mineworkings very local to me, including one major former drift 
 mine).  It certainly doesn't refer to all artificial cavities.

In my experience (en-US), adits are always associated with mining, almost 
always with drainage--I think drifts and stopes are the proper terms for other 
horizontal passages. (Well, stopes can be large and hollowed-out, but I 
digress.)

While tunnel might be used colloquially for anything you can move through 
underground, I think the commonly used and more correct term for a natural 
underground corridor is passage or passageway. (e.g., unusual features can 
be seen in the passage between the Crystal Room and Room Five.)

 +1

+1 But as always there are edge cases - for example it may be useful for
routing during preparing a trip. There are caves that
connect two points. For example Jaskinia Mroźna -
