That is correct, the sign says "I 787 North". However the wiki page for the 
destination:ref key states:

The key destination:ref 
<https://wiki.openstreetmap.org/wiki/Key:destination:ref>=* should be
used to specify the reference of the roads directly ahead as indicated on 
signposts, road
markings or similar. The value of this key should be equal to the value of 
the key ref
<https://wiki.openstreetmap.org/wiki/Key:ref>=* of these roads.

Note the last sentence. If the destination:ref must be the same as the ref it is going to, then this 
would be I 787, or else all the ways along the entire I 787 route should have their ref tags changed 
to indicate direction as well.


Well, it says 'should', not 'must', thus in this case using destination:ref="I 787 North" is a 
refinement of just "I 787". Maybe an improvement for the phrase in the wiki would be

"should be equal to or a further qualification of related to the value...".

Haven't analysed that, but if the destinations are signposted that way, it 
should be reflected in
the tagging.

Both tagging and wiki develop, hopefully forward. In this case, 
Key:destination:ref redirects
onto an old 2012 proposal, I'm probably going to resolve that soon with 
describing the current practice.

Re: [Tagging] destination:ref with direction?

2020-12-16 Thread Tom Pfeifer

Trying to understand your question, the way in your example is tagged:

destination Troy
destination:ref I 787 North

From the data consumer perspective, such tagging will generate a navigation 
instruction:
"turn slightly right towards Troy, I 787 North". This would be helpful as long 
as the driver
is able to recognise it on the local signposting.

What is written on the sign at this junction? If "North" is mentioned there I 
would be
happy enough with the tagging above.

I have seen the compass direction quite often signposted on major roads in the 
US,
thus the question boils down if it is considered to be part of the 'ref'.
A general tag for the compass direction is 'direction', which is used 79% (shy 
of 1 mill
times) on highways.

So for the interstate itself, splitting it into ref=I 787 and direction=N would 
be preferable.

which highway to get onto? But I don't see it mentioned anywhere, and in fact, the only thing the 
wiki page on Highway Directions in the United States mentions is putting the direction on the ways

[Tagging] Feature Proposal - Voting - vaccination=* and vaccination=covid19

2020-12-08 Thread Tom Pfeifer

Following the 14 days of commenting, the voting is open, 08 - 22 Dec.

Comments received are discussed in the "Discussion results" section.

Please remember the voting is about the single key, not a full scheme.

Voting question:

Do you approve the introduction of the vaccination=* key, the value vaccination=covid19, and the 
principle to name the illness or group of illnesses in further values in a compact form.

Well it's used 34x already:
https://taginfo.openstreetmap.org/tags/healthcare%3Aspeciality=vaccination
While it was not in the original healthcare proposal it has been added on 
6feb2017
and appears in translations of the page. I'd support it.


healthcare:speciality=vaccination
vaccination:covid19=yes


A "vaccination" subkey makes sense to me; remains the old discussion of
"=yes" lists, or semicolon separated values, i.e.

vaccination:covid19=yes
vaccination:influenza=yes
vaccination:measles=yes

vs.

vaccination=covid19;influenza;measles

As the healthcare:speciality key favours CSV, I'd recommend that for the subkey 
as well.

wiki: "If a medical practitioner or a medical facility covers several specializations, they could be 
separated by a semicolon", which was indeed part of the original proposal.

[Tagging] COVID-19 vaccination centres

2020-11-18 Thread Tom Pfeifer
With the first Covid-19 vaccines getting approved, many municipalities are planning facilities for 
administering mass vaccination. In Berlin, the two former airports Tegel and Tempelhof are planned,

along with some sports facilities.

This raises the question for appropriate tagging.

The healthcare key seems suitable, it typically describes the activity in the 
value.
The compact form 'covid19' is already used in various tags.

Thus, what about either

- healthcare = covid19_vaccination
- healthcare:covid19 = vaccination


Related tags & pages:

https://wiki.openstreetmap.org/wiki/COVID-19_-_How_to_Map
  related to the "staying open" mapping effort

health_service:prevention:vaccination=yes|no (455x, 80% no, no Wiki page)
which I see unsuitable as it does not use the healthcare key

healthcare:covid19, 7x (covid_test, hospital, 1 user, no wiki)

Thus the objects will be mapped according to the subjective perception, but statistically objects

[Tagging] religious bias - Re: Feature Proposal - Voting - (Chapel of rest)

2020-11-04 Thread Tom Pfeifer
I was surprised that this tag is rushed into voting despite the arguments against it even here in 
the tagging list discussions.


Let's summarize the criticism first, and look into the alternative "mourning 
room"

* Vollis (the proposer) 18 Sep: ""chapel" will be opposed by some for being 
religiously connotated"

* Peter Elderson 21 Sep: "I have heard mourning chapel, mourning room, funeral 
chapel, funeral room.
Chapel of rest does not seem right to me"

* Janko 23 Sep: images of chapel of rest and mourning room are most 
concentrated and on the target

* Clifford Snow 24 Sep: "Chapel of Rest" sounds to me more like a marketing term not something we 
should be using in OSM.


* Michael Patrick 24 Sep: 'Chapel of Rest' seems to be a dated UK specific term. ... The euphemistic 
'Chapel of Rest' is more generically known as 'Viewing /Visitation Service',

* 27 Sep: 'Chapel of Rest' seems to be one of those terms like 'Take the goat 
to the butcher...
* 28 Sep: since OSM is an international project, my practice is to make it as easy as possible for 
non-native English users.



Indeed, the proposed value contains 'chapel' which is biased to christian religion. It might be used 
in British English, however that is biased itself for having Christianity as a cultural background.


"Chapel of rest" is an euphemism that avoids death-related terminology, but might be mistaken for a 
chapel where somebody could rest along a hiking or pilgrim route. This is a general problem with 
euphemisms that they intentionally don't hit the nail on the head.


OSM so far is successful in choosing tags agnostic of particular religions, such as 
amenity=funeral_hall recently and amenity=place_of_worship long ago. Thus for this feature I'd 
prefer a value that is applicable to any religion as well as secular ones.


Looking deeper in the example of Place of Worship vs. Church:

The British Ordnance Survey did chose "PoW - Place of Worship" in their maps, and OSM apparently 
inherited that term, although probably nobody says in colloquial English that they "go to the Place 
of Worship tonight", if they go to the church or the mosque or whatever holy place.


However both the OS and the OSM maps remain politically correct when using PoW as the technical 
term, preserving neutrality.


OSM is a map for the whole world, and it does not improve acceptance when a bunch of old white males 
(such as myself) chose a biased term for a feature that naturally exists in other cultural/religious 
contexts as well. Thus that part of the world would need a different tag, leading to tag fragmentation.


To close with an alternative, "mourning room" would be a neutral alternative 
from my perspective,
reflecting the process of mourning which I suppose exists in all cultures.

So:
Please go and vote.

Indeed the main reason why my preference is not to use the contact:* scheme
is that its proponents did not limit the scheme to true means of contacting,
but tried to press everything into it that was not up in the trees when counting
to three.

The most prominent example is website, where only a page with a message form 
would
be clearly in this category. However what is more recommended to be mapped is 
the
basic homepage of a POI, because it is least likely to be changed in website 
relaunches.

The main purpose for me to read a website is to gain information about the 
object
and not to contact it.

In countries where an imprint is not mandatory, websites often do not even 
provide contact
details at all.

There are many more examples on the contact:* wiki page that are pure methods 
of dissemination
and not of contact, such as contact:youtube or even contact:flickr

How is contact:webcam supposed to fit into the scheme?

In contrast, postal addresses are a very typical means of contact, I can send a 
letter
there. So consequently, we would have to to move the "addr:*" scheme into 
"contact:addr:*",
which would make the scheme even more stilted.

I guess that contact:[phone|fax|email], and nothing more, could have won easily 
if the
scheme had not tried to include all the other stuff.

amenity=social_facility with subkeys social_facility=* and social_facility:for=*
was voted in favour in 2010 with an unusual 96% on a quorum of 28.
The only vote against was just about dropping the amenity key above.
It turned out as a big help to keep values out of the top-level amenity=* space.
The proposal explicitly excluded facilities for the "treatment of specific 
acute medical
conditions", giving hospitals as example.

With about a dozen values that have significant usage I cannot see that there
were "too many different features lumped together", quite in contrast to 
amenity=* itself.

The problem comes with the the dynamics of amenity=nursing_home and 
social_facility=group_home:

If you look into the history graphs [1] you see that in 2011 there was 
apparently a massive import
of amenity=nursing_home;
which was partially removed in 2012, and partially converted
into social_facility=group_home and social_facility=assisted_living

social_facility=group_home was an over-ambitious attempt, coming from the 
examples of the
social_facility proposal, to tag a "Retirement Home" as amenity=social_facility 
+
social_facility=group_home + social_facility:for=senior, which blurred the 
distinction
of which homes provide nursing.

The new value social_facility=nursing_home provides clarity and is becoming 
organically popular
without mechanical changes.

It would be helpful if somebody could provide insight in the 2011 import and 
the 2012 mechanical
edit, and by which criteria the nursing_homes were separated into group_home 
vs. assisted_living.

It appears to me that in particular the imported objects nobody knows and 
nobody cares about.

Yes there is inconsistent use of place=square, in particular for _unnamed_

As the place=* key is used to indicate that a particular location is known by a 
particular name,
a place=* tag without a name is fundamentally wrong.

(As the world is not black and white, there might be exceptions.)

In Germany alone I found >600 such taggings, and all I probed were:

1. not squares as in the definition, but small and insignificant paved surfaces, like a round piece 
of footway in a park, the service yard of a fire station, or similar.


2. they were all added by the iD editor, typically since 2018.

Thus my assumption is that place=square is suggested in an iD preset to 
unsuitable features.
Could somebody with sufficient iD insight check what that preset suggests, and why it does not ask 
for names?


Further I recommend that everybody checks their area for place=square _without a name_, evaluate 
what it is and adjust the tagging. This can not (!) be done mechanically, besides the issues with 
mechanical edits, because the correct tagging will differ (e.g. highway=service + area=yes; or 
highway=footway + area=yes), or the tag was correct indeed and the name has been forgotten.


Query for unnamed square in a bounding box: https://overpass-turbo.eu/s/ROw

I also suggest to update wiki descriptions of place=* tags, upgrading the "name=*" from "useful 
combination" to "required", and add that to validators.

Re: [Tagging] Updating definition and description of place=square

2020-03-22 Thread Tom Pfeifer via Tagging
I fully agree with Martin here. The place=* key is used in OSM to indicate that a particular 
location is known by a particular name, and that is independent of details of the usage.


It might be that Joseph's perspective is driven by his intense work on the 
Carto style,
where it has to be decided if a name is being rendered in the place-style or in 
the park-style.

However OSM is more than rendering, it is about analysing the data. And when I 
ask e.g. Nominatim
or Overpass where all the Squares in my town are, I wish them to be included by the place=square tag 
and not lose some where the place tag has been omitted just because they are filled with a park.

Squares are generally deliberately left / created open / spaces in contrast to

where the road enlargens, typically at crossings or placed as rhythmic 
sequences within a street).
They come in all scales, as big central places with significance for the whole 
city (or even nation) or as small squares  at crossings in a residential area. 
They might be frequent or rare, depending on the cultural context, and their 
characteristics will depend generally on context.
There is no need to impose arbitrary size limits or usage requirements (both, 
on the square and at its borders), nor to make the question of leisure=park 
junction=yes exclusive to place=square. They can perfectly coexist.

IMHO place=square is a tag for a toponym that refers to a void inside a built 
environment, and size and usage is implicit from geometry and other objects.

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

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

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

However, since this requires to provide evidence and send complicated forms

by a company that has booths in major airports. Thus participating shops
prepare a special receipt, and the airport office refunds the tax while

Literally it means that you park your own and ride another vehicle,

The point is that a mini roundabout does need a LOT of preprocessing to

junction.


Could you explain what the preprocessing is needed for, and why you need to replace it in the

From my perspective nothing is needed. The routing engine recognises from which way you come and 
where to leave, and, since the feature is so small and clear, it can give instructions like at a 
normal junction, just using the tag to describe the junction:

"At the mini-roundabout [turn right|go straight|turn left]".

Basically the mini-roundabout is effectively more about who has priority, and here all incoming 
roads have to 'give way'. Similar a four-side "stop" sign in the US. I have used them in Britain and 
they are often just a bucket of white paint poured in the middle of a junction.

Apparently there is a semantic difference. When someone counts 3 apple trees on a hectare, it is

- in developing countries, anything from secondary down (or even primary)
may be unpaved
- in rural areas of the US, it's not safe to assume highway=residential is
paved if tiger:reviewed=no


In the outskirts of Berlin, I have unpaved highway=residential in good 
neighbourhoods,
that are muddy when wet and dusty when dry. Thus Germany qualifies as 
developing country?

Now that residents are relieved from paying the state parts of the building cost of their roads from 
this year on, the situation might improve eventually...

Hi,

At least in Finland we have course centers maintained by non-profit organisations, for example

I'd see that very suitable. You can define the subtype by tagging community_centre=*, and I would 
not see a requirement that the facility needs to be open to everybody, it can be for a specific user 
group, which can be tagged with community_centre:for=* .

Re: [Tagging] Adding leisure=sports_hall to leisure=sports_centre page

Recently you [jesienbe] added to the wiki page for sports_centre that sports halls inside of sports centres 
don't need a leisure tag if the centre is mapped as an area. 


And this is wrong, as it fails the purpose of the leisure=sports_hall tag.

As I remember the tag development, any value like 'gym/gymnasium' was deliberately avoided because 
it has too many different local meanings, ranging from fitness over weightlifting over climbing gym 
over school sport up to the German word for a secondary school itself. [1]


Therefore the slightly more stilted leisure=sports_centre came into use for any facility where 
sports are performed and was widely accepted (183k).


This however led to the situation that
a) a simple school facility with a wooden floor and a changing room is not 
really a 'centre',
b) sport campuses with several buildings for different sports became tagged with 
leisure=sports_centre, and the buildings leisure=sports_centre again, inside of the campus.


The solution was found in 2018 with activating a tag with small usage that time, 
leisure=sports_hall, which solves both cases,

a) having a tag for a small individual facility,
b) having a tag for each of several facilities like the rowing hall, the climbing hall, the ice 
skating hall, you might have on a campus that is a centre for having a multitude of such facilities, 
accompanied by the sports pub.


This tag is growing rapidly since.

Any buildling=* tagging describes the original building typology and is orthogonal to the usage, see 
my other mail.


Please recognise that the world is not black and white, and there is a continuous spectrum of sport 
facility sizes. So while there are examples that are clearly 'just a sports hall' or a 'large 
centre', there will be edge cases, where the hall gets a reception that sells you a coffee, and then 
a little weight-lifting corner, and so on, so an individual decision would have to been made to 
decide to mark that as a hall or a centre.

Please understand that the building typology is orthogonal to the usage of the

Thus having both a building=X and leisure/amenity=X on the same polygon is not 
redundant.

If the usage changes to Y, and the building structure remains as X, it will be tagged building=X and 
amenity=Y.


This approach works in both cases, the tagging on the identical polygon, or the tagging being on the

No. You cannot add the value to the same key.

However, I believe that rarely used, proposed tags should be approved
through the proposal process or should become commonly used

If you look at the history, it is being growing organically.
A hint to consider a more suitable tag on the centre page tagging cannot hurt.


So, this can be a synonym for a sports_centre, or a tag for a building
found in a sports_centre?


More precisely, leisure=sports_hall is for facilities that are not centres.
Surely a centre can hold, among other facilities to form a centre, one or more 
halls.


Why not just use building=sports_hall and sports_centre for the whole area?


Because building=* describes the building typology, not the usage. leisure=* 
describes the usage.
Thus, a purpose-built sports hall is leisure=sports_hall+building=sports_hall, while a converted 
church that is now used for sports is leisure=sports_hall+building=church.

"capacity" is the well established for the number of items the facility can

"maxtents" is hard to understand, ambiguous and likely leading to confusion.

The wikipedia article has some insight in the process, however it also mentions that a mosque can be

I think you misunderstand. OSM is based on locally sourced, handcrafted data. That creates the high

Import means data are copied from another database into OSM. That means, somebody else collected the

even if they are labelled official, governmental etc.


IIRC the dataset you are using is several years old, last updated 2017. The items in your Umap do 
not say when the database entry was last checked.


Thus when copying these data into OSM, they appear as freshly updated, March 2019, although the 
information is much older and the hotel might have closed or changed ownership/pet policies/wifi in 
2018. In particular in a "stealth" import, one node at a time, I would assume the OSM data to be 
individually checked and current.


Thus your task is to discuss with the Italian community if your import, i.e. copying the other data, 
improves or decreases the OSM data quality. The changeset size is less important, though I would 
prefer an community-approved import to be traceable in not too many changesets.


Your colleagues data of 12 guideposts are fine if they are freshly collected

Re: [Tagging] Hotel dataset import? / Re: Baby-sitting

2019-03-09 Thread Tom Pfeifer

Giovanni,

I have severe problems with your process. First, yes it is an import. You called it an import 
yourself ("manually importing") here, and on the Italien list where you first asked about the 
tagging [2]. Where did you see a "100 nodes" limit documented? You are copying from one database 
into another, and if you do just one node a day, it is a slow import.


Imports require the Import Guidelines to be followed [4]. I cannot see any discussion with the 
community. I cannot see any check of license compatibility. There is no documentation. There is no 
entry in the import catalogue.


You were criticized for stretching the opening_hours syntax to describe seasonal operations ("Jan 01 
- Dec 31"), but did not respond nor adjust your tagging.[3]


The link on your Umap site leads to [5], which is licensed under the Italian Open Data License, 
linked here [6]. It requires attribution, machine-translated: "On condition of: indicate the source 
of the Information and the name of the Licensor, including, if possible, a copy of this license or a 
link (link) to it."


You have not attributed correctly. You changesets, e.g. [7], give in the CS comment "RAFVG source", 
which is an incomprehensible acronym if you don't know the context. The CS has no source tag at all 
(although the editor you use has a mechanism for it), thus you do not name the source correctly, you 
do not name the Licensor, and you do not include a link although possible. You have also not checked 
if the attribution on the changeset only would be sufficient.


Your import does not include any check, how current or old the data in the imported set are. In the 
hotel business, things can change very fast. Hotels open and close, and change ownership and 
operations.


Your import focuses on soft business policies, such as allowing pets or supervising kids. Such 
policies can change even more rapidly, and are better shown in separate datasets and not OSM itself.


You use and advertise in your umap the use of Level0 as an editor. This tool is excellent for 
quickly fixing a tag, but I would find it error-prone to upload mass changes without a validation step.


Thus I conclude: Visualising the dataset in your Umap approach [1] is an excellent idea, unreviewed 
copying of the data into OSM is not.

Thanks Paul, Markus, that's what I mean.

Thus it is more comparable to the addr:interpolation which we use before all addr:housenumber are 
mapped individually. Once we have achieved that, the interpolation line becomes obsolete.


So, once the trees are mapped individually, we have all the information we need. The tree_row is 
then unverifiable, as there is no definition where it begins and where it ends. As said before, I 
could call any two trees a "row", e.g. each pair of trees on the opposite sides of the road. Or, I

Both pylon and line exist, and both building:part and building are tangible

The tree_row, on the other hand, is a virtual collection of trees, and forming a row is just in the 
perspective of the observer. There is nothing tangible between the trees, once the individual,

Thus the tree_row is a simplification, because the mapper was not able to map

Otherwise I could just arbitrarily connect some trees in a park and declare it

[Tagging] tree rows vs individual trees

2019-02-09 Thread Tom Pfeifer

On the natural=tree page I stumbled over the phrase:

"Tree rows ... This approach can also be combined with individually mapped trees for 
further details."

On natural=tree_row I found it was part of the 2010 proposal which said:
"if individual trees in a tree row are mapped, the tree nodes should be part of the tree row way. 
Usually, however, it's not necessary to map the individual trees in a tree row."


In the discussion this was reasoned with:
"...connecting the trees with a way allows renderers to generalize the tree row into a single 
entity, rather than showing each tree separately"


IMHO this violates the one object - one OSM element principle. Either I choose the coarser approach 
to map a way for the row, or I refine it to individual trees, but should not use the row anymore.


If a renderer wants to cluster any trees that can be done algorithmically.

I suggest to remove the idea that tree and tree_row could be combined,
or even declare it should not be done.

I have never considered the 'religion' tag as an access tag. Typically I can freely enter a PoW, and

Similarly, educational institutions in my scope mostly accept children with different background, in

Using a new amenity value for a feature that we currently have about 300x in 
the database
leads to further tag fragmentation. According to previous discussion the 
alternative vehicles
are indeed called motorcycle taxi etc.

So, amenity=taxi lets the data consumer evaluate individual transportation for hire, and 
taxi_vehicle specifies it in more detail.

[Tagging] amenity=taxi vehicle type

2019-01-04 Thread Tom Pfeifer
Following a discussion on osm-carto [1], I am looking for a suitable tagging of taxi services that 
are not passenger cars.


Examples are motorcycle taxis and rickshaws.

While the original approval for amenity=taxi (32k) [2] does not specify the vehicle type, some 
additions were introduced in 2013 [3], apparently from the Philippines community [4], to add the 
following tags:


+ motorcar=yes|no (usage 289, mostly Philippines)
+ motorcycle=yes|no (usage 290, mostly Philippines)

The problem I see here that this method hijacks access-tags, while the intention is to specify the 
type of the taxi. The next best candidates for the type are also already occupied with access tagging:


taxi=yes|no (18k)
vehicle=* (203k)

Thus I propose to discourage the use of those access tags, and to use a new subtag for the type of 
the taxi with an unambiguous key, e.g.:


taxi_type = car|motorcycle|rickshaw, etc,
while car is considered the implicit default.

No I don't confuse it. The refilling proposal is about refills without

To top-up a drink is purchasing a new one without wasting another clean glass.

By which standard? I think it is marketing slang, as it makes no sense

Re: [Tagging] Feature Proposal - RFC - Top up

2018-12-26 Thread Tom Pfeifer

I find "top_up" alone highly misleading and unspecific.

I encountered the term in filling stations, where you would order either "5 gallons" or "top up", 
i.e. to fully fill the tank. Or when pre-paying the fuel, you would either pay "fuel for $20", or 
leave your credit card with the cashier to allow "top up".


In the same sense, you could ask the bar keeper to "top up" your cocktail glass.

In the context of pre-paying credits for phone or transport, there is no such "top", no upper limit, 
you could buy any amount you want. Thus this marketing slang is misleading.


It is unspecific to be used in OSM since it does not indicate which service is 
being paid for.
Using it on the object tagged with amenity=bar it gets absolutely confusing 
what is getting topped up.

Thus, I'd not use the term "top_up" at all, and as Martin proposed, indicate the type of service 
first, e.g.:

phone_credits=yes
transport_credits=yes
cocktail_glasses_topped_up=yes

Even 'credits' seem problematic, since what you pre-pay is not a credit.

The warning is useful when it comes only in situations that are different, such as a marked crossing

I encountered a similar situation as you describe, where some private gravel parking area in front

I agree with those that tagging highway=service + service=driveway should cause the router not to

In particular sports that are performed in a natural environment often have no sharp geographical

Examples are areas in a lake for sport=swimming, or areas with rocks where you 
can sport=climbing.
Unless there is a physical barrier, like a floating line in the lake, you are not limited how far 
you want to swim, but you would not use the whole lake. Similarly, a geolocation is known for good 
climbing spots, however you don't want to tag each boulder, or they are hard to map cause GNSS is 
poor under the trees and the rocks are not visible from aerials for the same reason.


Thus the location is surrounded by the physical object, but the tag is on a separate node, such as a

Well that's the old issue of trying to fit a tag semantically to equal natural language, which is 
not necessary.


In OSM a pitch can be a field where a particular sport is performed. Multiple pitches form a 
sports_centre.


If I am not interested what particular sport is performed there, it is enough to evaluate the pitch 
and the sports_centre tagging, and I know it is not a quarry. Keep things slightly structured.

Why not following the pattern of other repair shops, such as

The sites all look the same.

Some of them are on the site of a trucking agency and thus private, some are accessible at places 
where truckers come often, i.e. at the exits of large distribution centres, at motorway truck stops 
etc.


It's a spot where one would pull up a truck (or bus/touring car), then check whether the mirrors are 
right, and if not, adjust them. It would be rude to really park there.


I wouldn't make more than a node out of it.

Re: [Tagging] building = house vs detached.

2018-07-22 Thread Tom Pfeifer

Probably the reason can be explained etymologically.

In the UK, terraced houses (AmE row houses) are very common, so those lucky enough to hear less 
noise from their neighbours emphasize that by owning a 'detached' (not attached to a terrace) or 
'semi-detached' (two houses sharing a wall) building. The detached/semi-detached also allow outdoor 
access to the back garden, so the 'end-of-terrace' house is marketed with a similar advantage.


In countries where terraced houses are less common, there is less need to emphasize that the house 
is free-standing. Also, 'house' is easier to understand for a non-native speaker than 'detached'.

I've seen people say that house is meant for rowhouses, and detached should be for 
stand-alone houses, but there is no documentation that explains that. If that is the intended 
meanings of the tags, then the wiki pages need some work.


As far as how I've seen things actually mapped, I've only ever seen the building=house tag. Taginfo 
shows 1.2 million uses of detached, and 27.2 million uses of building=house, so they are both used 
quite a bit, but house is used a lot more.


Can anyone elaborate on these tags, or have ideas on how they could be better 
written about?

In some countries (like Germany) saunas are always naked, in others
(e.g. Ireland) that is definitely not the case, you're expected to wear
your swimsuit). I don't know if that's worth tagging or if data users
should just deduce it from the country.

– sauna=hot
   A Finnish-style sauna with a temperature of over 60°C because of the
water thrown on the rocks of the stove. This kind of sauna is relatively
dry because of the high temperature.
– sauna=steam
   A Turkish-style steam sauna with a lower temperature and limited
visibility because of the steam generated.
– sauna=smoke
   A Finnish-style hot sauna in which the stove has no chimney but
instead the smoke fills the room when the sauna is prepared, and the
smoke is then ventilated out when the sauna is ready.
– sauna=dry
   A non-steam dry sauna in which water is not thrown on the stove.
– sauna=aroma
   A sauna that constantly has an aroma. A Finnish sauna with occasional
aroma liquid added to the water is tagged as sauna=hot.
– sauna=infrared
   A sauna-like construction that is used for infrared therapy.

"Official" is what is used by data consumers - this is the case for the simple scheme, as there are 
3D renderer in the field.


... but for a castle entry, also 
tunnel=building_passage is needed. https://wiki.openstreetmap.org/wiki/Key:tunnel


The 'simple 3D' tags are used in addition to the other tags like width and height, so you can keep 
using the tunnel tag of course.


However please consider that 'simple' means it is not a fully fledged CAD system where you can 
represent every little detail. It helps to show useful 3D-outlines of a town.


At some stage it might collide with the interest of Indoor mappers, who want to represent indoor 
rooms and support indoor routing, most prominently in complex railway stations.

Exactly. I would not map anything that is not officially signposted with the

In particular the concept of a shared apartment is to make the life as normal as possible, that

I am getting more and more the impression that whole amenity=social_facility

the same time if we used duck tagging. amenity=nursing_home / orphanage / 
soup_kitchen / daycare / food_bank etc.
When needed you could still add the target group tag, but sometimes it is 
already implied.


I still consider the social_facility tagging system a success. It allows a data consumer to quickly 
distinguish e.g. an area with such facilities from an area with offices, without maintaining a large 
list of duck tags from the crowded amenity key.


As for the part of the world I live in, Charles Dickens-style 'orphanages' 
don't exist anymore.
Younger minors that are separated from their parents would be placed in foster families, or live in 
family-style structures following the SOS-Kinderdorf model. Juveniles live in supervised shared 
apartments (betreute Wohngemeinschaft). For the short term accommodation, there are group homes, 
however they would not primarily distinguish whether the minor is an orphan or separated from their 
parents for any other reason.

The building=train_station tag remains, since it describes the building type, independent of the 
current usage.


No. The building tag is for current usage. OSM maps the present with its primary tags. If 
contributors want to indicate it had previous use, as I do in this case, it should be tagged with 
clearly defined sub tags.


We understand that you have strong personal opinions, and remember the debate about exit nodes in 
roundabouts.


However the consensus with many other mappers in OSM is, as descried in the 
wiki:

"the [building=*] value may be used to classify the _type_ of building. Note that it may be not the 
same as the building's current use (tagged using building:use=*). For example, a hospital building 
that is abandoned or repurposed to be a marketplace is still a building=hospital, and to mark active 
hospitals amenity=hospital is used. "


It also perfectly reflects common language. Imagine the following BrE example:
"Do you see the church building over there? It is now used as a climbing hall!"


The building:use tag is inaccurately used. (I believe it shouldn't be used at 
all).


Again this is your personal opinion. building:use is well defined in the wiki, 
and used 63 times.

IMO this is poor tagging. If a building is now used as a place for people to live then it clearly 
isn't a warehouse any more.


No, but it has the building type of a warehouse. Ans some people like it, and 
say:
"Hey, I have an new loft in the old warehouse."


A separate tag is required.


We have two separate tags, building=* and building:use=, they are well defined and serve their 
intention. If your intention is different, I understand that, but that will not change our minds.
