 if that's the case, what's wrong with creating a node on the building for
 each additional valid address?  People looking for an amenity could look up
 closest POIs after finding a secondary address.  It's not a clean situation,

 It's a best guess approach, delivering lots of false positives, because
 the scope of address nodes is undefined. The address may be valid for the
 whole building, or only part of the building, or even for multiple buildings
 (take my postal address as an example).

But that's not precisely true. The scope of an address node inside a
building outline is this building. If you want to specify an address
for a part of a building only, just split that building.

 That's wrong, as I've already explained in another message. When you write a
 letter to an address in Austria using a conscription number, you MUST omit
 the street name. Otherwise the letter will be returned as undeliverable.

 Similarly, the official address at a given time either contains a
 street+housenumber or a conscription number, not both. In villages where
 street+housenumber combinations are introduced, the conscription numbers
 become officially invalid. The reason why we want to keep them in OSM is
 that conscription numbers often remain in use for a long time, and the
 conscription number plates often stay in place (see photos in the proposals).

Both statements are actually untrue.

Dmitry,

In most cases the address of a POI is the same as the address of a building
it's located in.  The address of a building can be derived from address
nodes within its outline ', and then extrapolated to other POIs in the same
buildings.  It doesn't work precisely when there's no outline, but in this
case you've already lost the precision.

Moreover, this operation has to be performed anyway to cope with really bad
and incomplete data, so there's no reason to not re-utilise this
functionally once again.

If your country has effectively abolished conscription numbers, this

used all the time. In my country, both numbers are used concurrently

  No, it's not two addresses, it's just a single one. It's just a
  particular feature of it that you can omit a part of it (either of the
  building numbers or sometimes the street name if you have the
  conscription number).

 I've got your point, but I cant agree with you that it's not a multiple
addresses tagging scheme.

It doesn't actually matter if you agree or not, because it doesn't change
the fact that buildings in CZ and SK don't have multiple addresses.

 Hello Friedrich,
 in Czech Republic they have a similar problem: They have so called
 conscription numbers, which are unique in the whole city and
 additionally the normal housenumbers.
 They use the key addr:streetnumber (675,742× used) for the number unique
 within the street, addr:conscriptionnumber (2,632,784× used) for the
 number unique within the city and addr:housenumber for both separated by
 a slash (tagging for the renderer?!).

This isn't actually a problem in CZ and SK at all. Conscription number
and street number are used by Nominatim, but they're intentionally not
rendered. Housenumber tag is left to be used as human-readable house
number (sometimes it's two numbers separated by a slash, sometimes
it's only one which is more appropriate in the specific context).

This particular proposal seems to be a terrible solution to this
problem. It requires changes to the software, and the tagging scheme
is ugly as hell. At the same time, there's much simpler and better
solution: placing address nodes inside the building polygon. This is
already used, supported by any sort of software which can process
regular OSM address tags, and it's not as ugly as addrN:.

Hi,

Some places in the wiki mention cycleway:lanes:* tags, and those are
indeed used in a few places (31 uses currently). It seems to me these
tags are obsolete and have been replaced by bicycle:lanes:*, is that
correct? Should I probably mass-replace them?

 there are any number of reasons why a consumer might use a

 attempting to approximate a fastest route.

There's one even more obvious reasons: displaying a speed limit to a

How do users find out what the maxspeed actually is there if they

Re: [Tagging] [osm_sk] Re: Aktualizace: Tags for Czech/Slovak address system

2014-03-10 Thread Andrew Shadura
Hello,

I think it's important to add both tagging@ and talk-cz@ to the loop,
as this question needs more serious consensus, in my opinion. I've left
the original message below, just in case anyone wants to translate it
from Czech directly.

In short, Dalibor proposes to use addr:place and addr:borough as a more
featureful replacement of addr:suburb, which I think is not very
justified and is against common practices elsewhere. His proposed scheme
is:

 addr:conscriptionnumber=220
 addr:housenumber=220
 addr:street=K úvozu
 ref:ruian:addr=28413113
 addr:place=Lochkov část obce
 addr:borough=Praha-Lochkov městská část
 addr:city=Praha
 addr:postcode=15400
 addr:country=CZ
 source:addr=cuzk:ruian

The Czech term ‘část obce’ here, in my opinion, exactly matches what is
‘a distinct section of an urban settlement (city, town, etc.) with its
own name and identity, e.g. annexed towns or villages which were
formerly independent’, which is a definition of a suburb. However,
addr:place is commonly used to define a part of address which has usage
similar to the street part, but isn't related to the street.

Speaking of addr:borough, the only difference I see between the
proposed usage of it and what would be otherwise addr:suburb is that
the official name of a municipal district may be not the same as the
name of a locality. Dalibor, please correct me if I'm wrong.

I wonder, do we really need to introduce new tags now and redefine the
meaning of old tags, or maybe we can fit this into the existing model
somehow? I think that maybe it's enough to have the districts and
boroughs as properly tagged boundaries, and to have addr:suburb set the
the official name of a municipal district, what do you think?

Anyway, I'd like to also hear the opinion of non-Czech or non-Slovak
members.

 Ahoj,
 dovolte mi přispět do diskuse a objasnit naše stanoviska.
 Předně ono je to o hodně složitější. Fakt. Zejména Praha. Viz 
 http://cs.wikipedia.org/wiki/%C4%8C%C3%A1sti_Prahy
 
 Ale od začátku:
 addr:place jsme začali používat a úspěšně používáme pro malé obce a
 části obcí
 (tady je třeba říct, že část obce je termín z registru RÚIAN a
 znamená v lidských termínech prostě malá vesnice, co nemá místní úřad
 a patří pod jinou obec),
 kde nejsou pojmenované všechny ulice. Před nějakou dobou totiž začal 
 Nominatim
 úspěšně hledat podle addr:place, když nenašel nic podle addr:street.
 Takže běžné adresy do malých vesnic jako je Libív 5 najednou šly
 najít, pokud měly addr:place.
 
 Teď se snažíme doplnit všechny adresy podle RÚIAN a tam používáme
 addr:place i ve městech, kde jsou používané ulice. A nevidíme žádný
 problém, protože addr:street
 máme pořád a navíc jméno části obce, což je ve městě rovno (podle nás
 i podle RÚIAN městké čtvrti).
 Jako bonus je, že se dá najít i dům podle čtvrti a čísla popisného,
 což je informace, která je uvedena v katastru.
 
 Jenže nad tím je ten zmatek s většími městskými částmi. Praha je sice 
 extrém, ale ostatní
 statutární města jsou taky nic moc.
 
 Naštěstí v RÚIAN je to o maličko jednodušší:
 
 Tady je jedno pražské adresní místo:
 http://vdp.cuzk.cz/vdp/ruian/adresnimista/28413113
 
 Do OSM ho přepíšeme:
 addr:conscriptionnumber=220
 addr:housenumber=220
 addr:street=K úvozu
 ref:ruian:addr=28413113
 addr:place=Lochkov část obce
 addr:borough=Praha-Lochkov městská část
 addr:city=Praha
 addr:postcode=15400
 addr:country=CZ
 source:addr=cuzk:ruian
 Rovnou upozorňuju, že neplatí, že by takhle podobné byly addr:place a 
 addr:borough všude.
 
 Tahle adresa ale má ještě další vyšší celky (dle RÚIAN)
 správní obvod - Praha 16
 městský obvod - Praha 5
 A tady asi nastupuje addr:suburb, který by mohl mýt jedním z těch
 obvodů, ale spíše bychom potřebovali dva. Mohli bychom použít
 district, ale ten máme už využit jako okres a ani jeden z těch obvodů
 není okres. 
 Borough je definován tady 
 http://wiki.openstreetmap.org/wiki/Key:place
 a vůbec nám nevadí, že zatím není addr:borough, to můžeme později
 dopsat a adresní tagy většinou vznikají jako dvojčata addr:něco a
 place=něco.
 
 Navíc použití suburb v OSM je prostě blbě. Suburb je periferie,
 předměstí. Že ho OSM poutíbá ve významu městského obvodu, části je
 sice možné, ale my se nechceme přidávat k špatnému používání
 anglických slov.
 
 Mohli bychom použít quarter místo place. To by bylo asi logické, jenže
 ne z pohledu RÍUAN, kde place je část obce, což znamená malou ves na
 venkově a čtvrť ve městě. To bychom si v tom pak udělali pěkný hokej.
 
 neighbourhood už je zase moc malé.
 
 Takže nám prostě vyšel place=borough a addr:borough jako lepší než
 subrub.
 
 Zdraví,
  Dalibor

Hello,

2014-03-10 12:01 GMT+01:00 Dave Swarthout daveswarth...@gmail.com:
 Just a quick reminder, the term borough has several meanings and could
 easily be misused. In Alaska, where I'm from, boroughs are large
 administrative areas — very similar to counties in the contiguous United
 States. So they are districts, in a sense, but perhaps not in the way
 intended in your example.

Which is exactly my point. The proposed scheme misuses some tags
(addr:place), adds new tags duplicating already existing (addr:borough
instead of addr:suburb) and adds more ambiguity by using the term
borough which may mean things different from municipal districts, so
I'm for reworking this scheme, but there are people who disagree with
me. That's why I brought the topic here for more discussion.
