[Tagging] Is it man_made=water_tap?

[Mateusz Konieczny via Tagging]

https://commons.wikimedia.org/wiki/File:Clickable_water_tap.jpg

You need to push button to activate (rather than turn handle)

Is adding man_made=water_tap to it correct?

Right now it is tagged as

amenity=drinking_water
fountain=drinking
man_made=water_tap

and the first two are clearly applicable (I think), but I am unsure about tap.

https://wiki.openstreetmap.org/wiki/File:Faucets_%E6%B0%B4%E9%BE%8D%E9%A0%AD_-_panoramio.jpg
is listed as example at 
https://wiki.openstreetmap.org/wiki/Tag:man_made%3Dwater_tap
and seems quite similar

IMHO yes.

The OSM wiki explicitly lists several examples with push  button taps.

https://en.wikipedia.org/wiki/Tap_(valve) tells

A tap (also spigot or faucet: see usage variations) is a
valve controlling the release of a liquid or gas.


This definition applies not only to screw-down but also to push button taps.

The further text describes different types of taps. Amongst them:


The term tap is widely used to describe the valve used to
dispense draft beer from a keg, whether gravity feed or pressurized.


If a pull-type tap is so widely called tap, a push-type does IMHO
qualify too, as it is only inverted direction of movement.

Georg

I see value in mapping whether given amenity=drinking_water
is a proper tap or just providing miserable jet of water making
impossible to fill water bottle.

Also, I noticed that many bare amenity=drinking_water are in 
various ways quite likely to be problematic 
(misplaced, used for water taps without drinkable water or
inaccessible to public and soon)

I would say that regardless of how it's operated - turn handle, push
button, lever, foot pedal, auto sensor etc - that if water comes out, it's
a tap!

Must have the ability to control the flow of the water to be called a tap.

so the "tap" word implies some kind of valve, having just a tube to channel
erogation does not count, even if it has the "right shape", right? Is there
agreement for this definition?

The "tap" is the device to control the flow.  Often, but not necessarily, at 
the end of the pipe.  If the user cannot control the flow, there is NOT a "tap" 
present.

around here, the typical drinking fountain is an iron cast column with
permanent flow. There is a water tap inside the column but the "user"
cannot open or close it (unless the cover is open, happens from time to
time, but is not the regular situation).

So the "user" cannot control the flow, but technically, a tap is present.
Shall we ignore this tap because it is usually neither visible not
accessible?

IMHO, if the user cannot (normally) access it, it is not worth mapping.  Or, do 
you want to micro-map every control valve (same function as a tap) in the water 
supply system, including those that cannot be seen?

I would not use the tag man_made=water_tap for these.


Why not use https://wiki.openstreetmap.org/wiki/Key:fountain


You will note the different tags - some relate to the 'style' of the 
structure others relate to the water delivery eg mist, bottle_refill .. 
thus the tag is used for anything.


The word 'type' in the description is the probable source of this 
confusion.

We introduced the fountain tag particularly to distinguish different
drinking fountain types around here. You are right that somebody has
"hijacked" the key and uses it with values like "mist", and
"bottle_refill", which seem to be describing something slightly different,
on the other hand it could still be seen as kind of the same property.

Err no. They are different properties - visual appearance vs water flow.

it is about fountain typologies according to the system that fountain proposes 
(arguably it is not complete or finished). “bottle refill” which you mentioned 
as outlier, as far as I understand it, is used for specific machines built to 
refill water bottles (or glasses), not for any kind of fountain where you can 
refill a bottle (sometimes it is not geometrically possible/convenient to do 
it, eg bubblers). Also “mist” can be seen as a type of fountain, as is splash 
pad. It is true that sometimes the kind of water flow is implied, but this is 
not the criterion in general

Present on the fountain page;

Styles?

nasone 'style' Literally meaning "large nose"

toret 'style'  The water is running out of an iron cast bull's head.

roman_wolf 'style'  water is running out of an iron cast wolf's head and 
for easier drinking there is a hole on the top where the water ejects 
when you cap the lower hole.


wallace 'style' green cast iron Possibly these could have 
designer=wallace?, material=cast_iron and colour=green



Material?

stone_block - 'material' .. so use the key material?


Water delivery?

nozzle

mist

bubbler

splash_pad

Re: [Tagging] Is it man_made=water_tap?

[stevea]

Water "tap" implies at least some (even if crude) control of the flow.

I don't know where the rest of it goes, but if you are "tapping" water (at a 
drinking fountain, a sink, as a plumber...), you strongly imply, if not 
guarantee, that you allow some control over the flow of it.  To call it a water 
"tap" automatically (in my mind, understanding, life-long experience...) means 
"valve" (somehow, somewhere, and if there isn't one, and you are a plumber, 
perhaps it is Job 1 to install a valve).

There is a similar one in front of Matthew Flinders Statue, Macquarie 
St, Sydney. Its cleanliness varies .. there is a more modern one across 
the road and further south if it is too bad.

'taps' also come with other things for example showers. It you map a 
shower .. does that not imply a tap? Similar for bubbler?


Renders may map the 'tap' instead of the shower/bubbler if both are 
tagged. I'd rather not confuse them.

This is why I said "if it's got a user-friendly valve," like if you press a 
button (and a stream shoots up to your lips to drink), wiggle a stem so water 
falls down (on your hands to wash), step on a lever (and the flow 
begins)...yeah, these things have a knob / lever / valve (maybe it rotates, 
maybe it needs to be "pressed"):  these are water_taps.  You might wash your 
hands, you might flow gently upwards in an arc for your lips, you might cause a 
light flow to drip or flow downward.  The "valve" (of many sorts), makes it a 
"tap."

begins)...yeah, these things have a knob / lever / valve (maybe it rotates, maybe it needs to be "pressed"):  
these are water_taps.  You might wash your hands, you might flow gently upwards in an arc for your lips, you might 
cause a light flow to drip or flow downward.  The "valve" (of many sorts), makes it a "tap."


I'll add to this list all those taps that can be activated without a 
direct manipulation of an object, such as passing your hand in front of 
a light ray which causes the water to start flowing.

The objects being manipulated in this case are photons.

Maybe you are being needlessly pedantic or "splitting hairs" (getting lost in 
the minutiae of details), I'm not sure.  But I think asserting "if there is a 
valve (and there are many sorts of valves), it's a tap" is fairly clear.

I'll add to this list all those taps that can be activated without a direct 
manipulation of an object, such as passing your hand in front of a light ray 
which causes the water to start flowing.

I think your definition is perfectly good. I was just pointing out that 
other kinds of devices using valves exist that don't always require 
manipulation of any object.

Yep!

If they don't exist already, pretty soon you'll be just able to say "Turn
the tap on - harder - now warmer - no that's too hot - yep, that's right -
now turn it off, thanks". Which will all be *much* easier than just turning
a tap! :-)

Thanks

And if one wants to define exactly how that flow is controlled, there is:
