Prague: conscriptionnumber+housnumer in housenumber?

Hey,

it was brought up in the german forum, that you are adding the conscriptionnumber into the housenumber. For example https://www.openstreetmap.org/node/296455474

Interestingly the bar itself https://www.openstreetmap.org/node/5691128621 is tagged just with housenumber (correctly, in my opinion), according to http://www.laviebistro.cz/kontakt/
On the otherhand https://www.openstreetmap.org/node/3597879399 is tagged again with conscriptionnumber in the housenumber.

What is the reason to include the conscriptionnumber into the housenumber? Because housenumbersearch is not possible anymore.

Best regards

Hi,

You can refer to this https://wiki.openstreetmap.org/wiki/Cs: … %A9m_adres (only in Czech). So your examples are correct ones according to Czech address system because "conscription / street number" = house number.

Hi,
regarding to lavier bistro: we are mostly using special address points. In this case, the correct address point is https://www.openstreetmap.org/node/296589107 with complete address. Address tags on POIs are optional and could be incorrect.

https://forum.openstreetmap.org/viewtop … 18#p820318 Here is the thread in the german forum, btw. sorry for missing the link.

So, taking this example: https://www.openstreetmap.org/node/296589107

If i want to write a letter to there do i have to write on the letter:

Name Surename
Mánesova 311/13
12000 Vinohrady

? Officially? Or is Mánesova 13 official? Or is both valid? Trying to understand smile

Looking at some restaurants http://www.usadlu.cz/kontakt.php (was there already, liked it big_smile), https://cafebuddha.cz/, https://www.tomsburger.cz/ or http://axello.eu/kontakty-2/ it seems like both is in use or valid?

Officially it should be Mánesova 311/13, but Mánesova 13 will also works. This system is used in bigger cities with long streets and many buildings so you can easier find the correct house.

The Conscription number 311 is unique in Vinohrady and Street number 13 is unique on Mánesova street.

Check: https://wiki.openstreetmap.org/wiki/Key … tionnumber

Btw: this building has more entrances from different streets: https://www.openstreetmap.org/way/28090508 ( https://www.openstreetmap.org/node/2753193054 / https://www.openstreetmap.org/node/2753193053 / https://www.openstreetmap.org/node/2753193052 / https://www.openstreetmap.org/node/1166275851 )

Re: Prague: conscriptionnumber+housnumer in housenumber?

I wanted to start this discussion as feedback on how the OSM data is usable by outsiders.
Sorry for dicuss in english.

On my first visit to Prague, I found that my navi was of little help in finding addresses.
It is factually not possible to do usual searches, like to a hotel or a museum for their addresses.
Example:
I search "Lázeňská 9, Prague" (= https://www.openstreetmap.org/node/296588542 ).
The first hit is https://www.openstreetmap.org/node/1433291400 :-(
The second hit is https://www.openstreetmap.org/node/1433008964 :-(

I then saw on the spot that there are apparently two different numbers, but nowhere was "addr:conscriptionnumber" used as the postal address.
Not on any bill, not on any website.

It's perfectly fine to record the "red" number that way on your end. ( https://wiki.openstreetmap.org/wiki/Key … tionnumber )
It would be helpful to record the "blue" house number as addr:housenumber, as is the international practice. This is also with you a pair with the street name.

But somehow I can't believe that it should be an "official" number, both individually labeled numbers separated by a separator "/".
It seems more logical to me if it was officially "NumberA" and "NumberB" and not "NumberA/NumberB".
If you want or if it is actually correct, then you can introduce e.g. something like addr:official_numbers="NumberA/NumberB".
Never use "streetnumber" as "housenumber", because it's not the nuber of the street.

Think about more international tagging and help your neighbors ;-)

Thank you

Hi Pyram,
unfortunatelly I can't share historic details as this tagging schema was discussed and approved by Czech community long time ago, before I joined OSM in 2013.

But this is the official address. Check your example in official registry: https://vdp.cuzk.cz/vdp/ruian/adresnimista/21697281

Especially part:

Adresa dle vyhlášky č. 359/2011 Sb.

Řádek 1:	Lázeňská 289/9
Řádek 2:	Malá Strana
Řádek 3:	11800 Praha 1

Several years ago we've imported all addresses from this registry. Details were discussed on import mail list. It was not easy to get approve. E.g. we were not allowed to touch already correct addresses just to delete obsolete tags like "is_in". So I can't image such action as retagging huge volume of address points. Also there are no resources and motivation to do it.

It is not an technical issue as we have an script that sync RUIAN data to OSM. it is mostly administrative issue. Like get discuss and get community approval, identify and notify projects about the change, discuss and get approve on import mailing list. It is outside our current possibilities.

Sorry and regards,
Marián
