  Some of our raw water sources do have a 3" fitting we use to draft
water. What's more common though in my fire district is "suction_point"
is where I park a fire truck and just drop a 3" hardline into the pond
or creek. Since these locations must be flat, and less than 10ft above
the water source (hard to find in the Rockies), we tag these so newer
responders can find them.

  A water pond or cistern with a 3" connection I'd consider a dry
hydrant, which just means there is no pressure behind it.

Sounds basically reasonable to me.  The page does not make it clear if
this is just a place you can put a hose in, or if the piping is
pre-installed.  What I'm talking about is a red 3 or 4" pipe that runs
from under the middle to the edge with "FD Water Source #6" sign or some
such.   Maybe that's what

  emergency=fire_hydrant + fire_hydrant:type=suction_point - strange 
alternative tagging

is all about.

But I don't see getting that straightened out as a bar to what you want
to do.

That's exactly the kind of thing I meant.  So no objections to your

So sounds like you are not going to remove landing_site?

In addition to real helipads and merely planned places, I have also seen
a crazy-extra-wide turning circle at the end of a road to a ~mountain
hiking trail, with paint marks that are obviously about helicopters.
But I am 99% sure this is for medevac only -- I think they just expect to need
it more often given the trail steepness, and there wasn't anything
close, so they cleared and paved a 100' circle (and you can park around
the edge only, IIRC).

Indeed the Germans are picky about these things ;-) But suction_point and the pond are two different 
things. The first could also be some pre-installed pipe in a stream, the pond is a dedicated feature 
often prescribed in the planning permission when you erect something, and might need to be 
maintained so it is filled. The first is a point, the second is a water body.

Yes, I agree entirely! That was the suggestion made previously that I

At least from the Aussie side of things, they can sometimes be moved by
choppers (Police or military) but SES don't own any choppers of their own.
They do however have boats as they are also used for flood rescue, which I
guess already makes the nice clean land / water split a bit murky

  Yes it will need a bit of work! The breakdown I suggested before was very

Yes it would be. At the moment I'm mapping NSW Fire Station locations &
updating their details, & I've found a number of places where the Rural
Fire Service & the SES share a shed - ones an amenity=fire_station, but the
other is currently just a building - how do we put 2 tags on the one
building, when they are both equally important?

Ambulance stations are a different thing again, which are tagged as
emergency=ambulance_station, but which, for some reason I've never
understood, don't render at all, while Police & Fire do?
https://wiki.openstreetmap.org/wiki/Tag:emergency=ambulance%20station?uselang=en-AU
& why the mixture between amenity= & emergency=?

No, I tried to clarify that when I brought up about tidying up the various
Lifeguard listings a while back, but never got very far :-(

Basically, a tower is taller than a platform, usually an enclosed structure
rather than just an elevated seat, & may well be a permanent structure.

I've made this change. In generally, now that we have taglists for
most parts of Map Features, it would be good to have a longer list at
each Key: page (e.g Key:emergency, Key:route, Key:amenity) and a more
consise list in the Map Features templates.

That may be, but would required an approved proposal to deprecated the

Ok, that makes sense. I actually know of a number of these which I

Don't they sometimes use helicopters too?

That seems sensible, but it needs to be clearly defined what qualifies
as one of these places.

Is a "Search and Rescue" center one of these?

What about a place that dispatches ambulances?

The wiki page for emergency=water_rescue_station suggests that
emergency=lifeguard_base should be used instead, so that needs to be
cleared up.

Re: [Tagging] What values of 'emergency=' should be on the main Map features page?

[Joseph Eisenberg]

The difference between emergency=lifeguard_tower and
emergency=lifeguard_platform is not very clear.

Recall that the original question is about what tags should be
included in Map Features, the introductory page, translated into may
languages, which represents the most commonly used, "de facto" and
"approved" tags.

That list is curated through the proposal process and discussion on
this mailing list and the wiki, generally tags should not be added
unless there is wide consensus that the tag has been accepted by the
global mapping community as the "de facto" way to map a particular
feature.

I am not questioning the use of any of the tags.

I like the distinction between marine and water, since lifeguards mostly
just deal with swimmers near shore and water police, marine rescue go
further out and respond to incidents with water craft.

At least for now the three lifeguard tags, emergency=lifeguard_base,
emergency=lifeguard_tower and emergency=lifeguard_platform are all well
defined, so at least in the near term we should keep using them.

Being visible on Map Features makes these tags easier to find for
newcomers. Even less common features should be there otherwise we'll just
end up the more popular tags getting used even more and the less common
tags won't and so OSM misses out on valuable data not being entered since
newcomers don't realise they can map it in OSM.

I disagree, this tag is well defined and documented, I agree it seems to be

the emergency key is better since it may not be nearby or related to roads
at all.

I disagree. I believe the iD preset is just emergency=lifeguard but that's
like highway=road just a placeholder until you can choose the more specific
lifeguard_base, lifeguard_town, lifeguard_platform.

The wiki does an excellent job at highlighting the differences.

As others have said, emergency=landing_sites are different to helipads, as
per the ongoing discussion re airstrip / airfield / aerodrome. In
Australia, we have just finished mapping ~700 of then throughout New South
Wales in connection with the current bushfires (which I'm sure you've all
heard about :-(), & are looking at doing the same for other states, to show
spots that choppers can land if needed.

With regard to =mountain_rescue. As was mentioned earlier, there may only
be a few of them mapped, but in those areas they are vital! I know there
also used to be a listing for emergency=ses_station for the Australian
State Emergency Service bases, but that appears to have been removed at
some stage?

On the discussion page for it
https://wiki.openstreetmap.org/wiki/Talk:Tag:emergency%3Dses_station, it
was thought that the name was too country specific, & the suggestion was
made to possibly rename these to =land_rescue_station, similar to the
existing =water_rescue_station
" There is an existing tag for emergency
=water_rescue_station
 and
given the diverse nature of at least the Australian SES, I'd suggest a

as
it would be easy to verify on the ground. It would also resolve confusion
in mapping marine SES units to the water_rescue_station rather than
SES_station which spans both. So the land_rescue here means a rescue
service where the main mode of transport of the responders involved is a

There would seem to be possible grounds for a new tag of

emergency=rescue_station + rescue=marine + operator=Marine Rescue
Queensland + name=Marine Rescue Currumbin

Lifeguards could then come under the same classification using water rescue

emergency=rescue_station + rescue=water + operator=Gold Coast City Council
Lifeguard Service + name=Lifeguard Tower 14

Keep it.  Fixed hoses are quite common in large buildings.  However,
like most indoor features, they're not mapped very often.

This is an emergency=landing_site: it's a section of parking lot that's
been surveyed as having sufficient clearance for a medivac helicopter
to land.
https://www.google.com/maps/@47.7487547,-117.5297687,75m/data=!3m1!1e3

This is an aeroway=helipad: it's a dedicated helicopter landing area,
designed and marked as such.

Around me, there are things that meet this definition, and have
standpipes installed.  So it's quite verifable.  However, if the pipe is
tagged as some kind of hydrant, and the water is tagged, that seems
sufficient.

I have seen, in company parking lots "evacuation assembly point #6" or
signed for some floor/building.  These are for people, not  a highway
thing.   I think it makes sense to map them.  Do you think this usage is
what the tag is about?

There is a difference between a helipad and a place for an emergency.
Around me helipads are fenced and have lights, and landing there is
within normal practice.

There are also pre-planned sites for medical helicopters to land, and
these are definitely not helipads.  They are merely places that are hard
enough surface and open enough (no poles or wires) that a Medflight or
police helicopter pilot can safely land and take off from.   Almost
always some fire department equipement/people are sent to secure the
landing site and provide lighting / denote the center with headlights.

These are verifiable, by talking to the fire department people or
observing them being used.

Perhaps there should be some other tag, but the concept is entirely valid.


(I am unclear on map features vs key values.)

In general it might make sense to have the complete list on the key page of emergency, and a 
selection on map features.



Like some other key pages, the Key:emergency page is a big list of
features generated from a template, and the same template goes
straight to the main list of Map Features.

This is probably why the Map Features page section for "Emergency" has
24 values, even though half of them are rarely used and very few were
every approved.


Be careful not to look into lower absolute numbers for features that exist in reality only in low 
numbers.


Discussing some of your reasonings below:


) =mountain_rescue - "A mountain rescue base for a team providing
search and rescue services in mountainous environments" - 185 uses
- Remove: rare tag, only relevant in some regions.


Quite important in those regions!


2) =fire_water_pond " A man made or natural pond with water for a fire
department." 2785 uses
- Remove: This tag isn't verifiable, or else it could be added to any
pond or small lake. It's not much used outside of Germany.


Why is that not verifiable? Such ponds typically have a red-framed sign 
"Löschwasserteich".
Ground-verifiable, not necessarily Bing-verifiable.


3) =access_point "A sign number which can be used to define your
current position in case of an emergency" -  uses
- Remove: the similar tag 'highway=access_point" is much more common
and was approved.


This is a good approach to improve tagging of emergency features by aggregating them under the 
emergency key, in particular those that are not highway features.



) =landing_site "Preselected flat area for a helicopter to land in an
emergency" 2543 uses
- Uncertain: the tag aeroway=helipad is more common, and the
distinction  is unclear


The distinction is that aeroway=helipad is a purpose-built infrastructure,
while emergency=landing_site is a predefined spot that is only used if there is 
an emergency nearby.
This could be a meadow, and there might be an agreement with the farmer to cut 
the grass regularly.


(I think it will help to use a separate list at Key:emergency, which
can be longer than the "official" list of Map Features.)


Yes. I noted that the language-translations of the Key:emergency page are quite 
heterogeneous,
some having their own list, some used the Map features list. Probably there should be a template 
separate from the Map features template that can be included in each of them. Do you know how to 
handle translation of the subheadings in such case?

[Tagging] What values of 'emergency=' should be on the main Map features page?

[Joseph Eisenberg]

Should we remove some of the rare values of "emergency=" which have
got into Map Features?

Like some other key pages, the Key:emergency page is a big list of
features generated from a template, and the same template goes
straight to the main list of Map Features.

This is probably why the Map Features page section for "Emergency" has
24 values, even though half of them are rarely used and very few were
every approved.

These are the ones that seem questionable and maybe should not be
shown on this page for new users:

1) emergency=fire_flapper "A wildland firefighting tool also called a
swatter or a beater. It is designed for extinguishing minor fires in
rural areas such as heaths." - 46 uses
- I plan to remove this from Map Features

) =mountain_rescue - "A mountain rescue base for a team providing
search and rescue services in mountainous environments" - 185 uses
- Remove: rare tag, only relevant in some regions.

3) =drinking_water - "A facility that provides drinking water in
emergency situations" 1155
- Remove: it was just added, and definition is confusing

2) =fire_water_pond " A man made or natural pond with water for a fire
department." 2785 uses
- Remove: This tag isn't verifiable, or else it could be added to any
pond or small lake. It's not much used outside of Germany.

3) =access_point "A sign number which can be used to define your
current position in case of an emergency" -  uses
- Remove: the similar tag 'highway=access_point" is much more common
and was approved.

These 3 I don't know how to handle:

) =fire_hose "A high-pressure hose used to carry water or other fire
retardant (such as foam) to a fire to extinguish it." - 1115 uses
- Uncertain: rather rare tag, though it does not seem to have any problems

) =landing_site "Preselected flat area for a helicopter to land in an
emergency" 2543 uses
- Uncertain: the tag aeroway=helipad is more common, and the
distinction  is unclear

) =lifeguard, lifeguard_base, lifeguard_tower, lifeguard_platform -
none is over 700 uses, total is under 1500 combined.
- Not clear how to distinguish these - should any be on Map Features?
Just "emergency=lifeguard", the most common?

can be longer than the "official" list of Map Features.)
