currently there are
5 480 building=train_station
1 349 building=station
335 building=railway_station
10 building=railway station
10 building=railway_station;train_station
9 building=pumping_station
8 building=station_building
1 railway:historic=station_building

so the very much are tagged train_station or station

I'm sympathetic to that, but what tag goes on the building way other
than building=yes to denote that a building is a station building?  Or
was?

Perhaps
  railway=station_building
  historic:railway=station_building
would be appropriate.

Perhaps; but disused has a different connotation in rail=disused.  But
if disused: is a prefix generally used for many things (e.g, a
restaurant that is recently closed and might reopen might be
disused:amenity=restuarant).

To me the key point is that a naive renderer that doesn't understand
historic/disused won't end up with the wrong values.

I prefer the historic: prefix.

Again I would flip to historic:railway, but as long as there is an
OSM-wide convention it of course doesn't matter.

I think the "this building is of historical value" is totally separate
From "this used to be a foo", and should be decoupled from
the railroad-specific discussion.

I dimly remember now that around Boston, station tags for non-terminal
stations (on commuter rail, but they are typically stations that have
existed since the railroads were built in the mid 1800s) are often nodes
on the rail ways.  Then there's a building on one side, which may or may
not still be a station building (typically not, but if the coffee shop
sells tickets, maybe it is???).  As for multiple buildings -- that's a
good point -- I was thinking about the classic one-building station.

So I think there's still confusion around "station site" and "station
building", especially because in the present, railway=station means the
site and we don't really denote the building.  In the historic:,
railway=station is the building and railway=station_site is the place.

(I'm a native speaker of US English, and an amateur radio operator.)

In the US, we use "tower" in several ways:

  fire tower - a structure with stairs and a room on top for looking for
  fires.  This is tower_type=observation, I think.

  antenna tower - a structure that may or may not be guyed intended to
  support antennas.  The tower is the structural part, and the antennas
  are used for receive/transmit.  The guying is not considered that
  important (the structural people of course have to get it right, but
  it doesn't cause people to call something a tower or not a tower).

  (very rare) coastal defense tower - set up for observation, to
  control artillery, so it should get tower_type=observation, in my
  view.
 http://www.capemayviews.com/Views/Misc/coastal_defense_tower.htm

I do not recognize the mast vs tower (guyed vs unguyed) notion in
wikipedia as generally valid, although a lightweight guyed pole for
temporary use might be called a mast, whereas a permanent structure that
is more substantial than 2" pipe is usually a tower.

In UK English, the word "aerial" is used instead of "antenna".

I have the impression, not well substantiated, that what I would call a
tower in the US is often called a mast in the UK, particularly if it is
not particularly tall and not built of steel lattice.

Stations that broadcast on MF (0.5 MHz to 1.7 MHz, more or less)
typically use the tower itself as the radiator, while VHF and up
stations have antennas at the top.  But from the OSM viewpoint, I don't
find that particularly importan.  (Also, in general I think JOSM presets
should support what taginfo shows as common, rather than leading the
way.  But I don't know if that's the normal view.)

So I am inclined to keep
  man_made=tower
with tower:type either communication or observation.
This is how I experience josm now, and it seems like it's right.

There are also poles for "streetlights", or things like that.
I would not call them towers, because they are not substantial or tall
enough for that.

Yeah, that's actually what prompted this discussion - I was pointed
there by Andy Allan when I commented on some OpenCycleMap rendering
peculiarities.
I guess there is a complete continuum between "there is an active
train station here" and "there was once a train station here, but now
there is nothing but a memory":

railway=station (active)
disused:railway=station (temporarily or recently inactive)
railway:historic=station (a building that was formerly a station, and

railway:historic=station_site (less than a building - maybe a marker,

Do I have this right? How does one tag a station that is active, but

I can't speak for others, but "building=yes" is the only building tag
I ever use. Otherwise you get into a double tagging mess. So I put a

[Tagging] tower vs mast vs antenna

2013-02-06 Thread fly
Hi

I was trying to get a common tower preset working for JOSM [1], when I started
reading about the terms on wikipedia (english).

As I am not a native speaker, I  like to ask natives about there thoughts but as
far as I understood it.

What we call man_made=mast is still a tower and man_made=antenna should be mast,
where as antennas are only the transmitter/receiver.


Any Hints ?

Thanks

Re: [Tagging] Amenity=shelter for field shelter?

Makes sense. So we're back to amenity.

Something like amenity=shelter + shelter_type=field_shelter + (if
necessary) access=private should cover it.

It exists amenity=animal_shelter [1] for large structures with a staff that

On taginfo already exists animal=shelter, and in many cases it has been used
to tag what now is tagged with amenity=animal_shelter. The migration is slow

For consistency with other shelter's tags [2], I would use:
amenity=shelter
shelter_type=field_shelter
The availability can be specified by access=* tags.
After all if you need a shelter against bad weather, you can use also a
field shelter, if it is accessible. In this sense consistency with

Agree to a certain degree that it should be freely accessible. It
depends on the context if this is given for a field shelter. In my
experience in areas with low population density you might find shelter
in a place like this e.g. when caught by bad weather. As always, its
up to the mapper. I wouldn't use amenity when the field shelter is
locked up.

I think this would put more implication into amenity than what it
practically has in OSM (see e.g. amenity=parking, access=private or
amenity=prison or ...)

I'd go for the more specific building=field_shelter (but also
building=shelter if you prefer) for the building-tag, or also
building=roof if mostly open.

amenity=shelter would be OK for me

Don't find shelter_type a very good choice (IMHO it would be more
logical to use shelter:type, but checking actual usage "shelter_type"
is the established key).

Also the value "field" is not very appealing (sounds as if the "field"
itself is a kind of shelter).

So trying to remove ambiguity as much as possible you could tag this:

building=field_shelter (or building=roof, layer=1)
amenity=shelter
shelter_type=field_shelter

I think the UK ones that are technically mobile aren't necessarily
actually moved --- it's just that they have to be moveable within a
set period (I think less than 24 hours) if there's a complaint about
them.  So it may well still make sense to map them.

Actually if amenity is not a good choice I would rather go for
animal=shelter instead of building=shelter. Maybe the key animal seems
to be a good idea for "amenities for animals" just a thought.

I only think about field shelters that are _not_ mobile. In the UK
they are more often - but not always - mobile because of some legal
reasons. In other countries they are often fixed. I'm only concerned

Sorry, but the picture is not a stable.  It is, in the UK, a field shelter.  
The other problem with mapping some of these is they are often designed to be 
mobile to get round planning rules.  The image is a mobile version.  There have 
been previous discussions on this, so you might want to search on the mail 
group.

I'm not sure I'd map this mobile type as it will probably/should move in the
