Strange Admin Boundary in Slovenia

Hi,

i found one admin boundary that does not make sense to me: Upravna Enota Litija(7) https://www.openstreetmap.org/relation/4184372

This boundary is overlapping 2 AL5-Areas, which is usually not ok.

In wikipedia i found "Traditional regions and identities" https://en.wikipedia.org/wiki/Slovenia# … identities
May be it's one of those?

Regards
Walter/Germany

btw: my main "job" is quality analysis of worldwide admin boundaries; see my signature.

Re: Strange Admin Boundary in Slovenia

Yes, this is a known anomaly in the administrative area hierarchy in Slovenia.

Upravna enota Litija contains 3 municipalities:
- Litija
- Šmartno pri Litiji
- Ivančna Gorica

https://www.gov.si/drzavni-organi/uprav … ta-litija/

Yet
https://en.wikipedia.org/wiki/Central_S … cal_Region
Contains Litija municipality

And
https://en.wikipedia.org/wiki/Central_S … cal_Region
Contains the other two municipalities

Thanks for keeping a sharp eye on our government ;-)

Re: Strange Admin Boundary in Slovenia

Actually, revisiting the issue I noticed that the relevant law in article 16 defines:

(4) Meje statističnih regij se v registru prostorskih enot spremenijo na predlog organa, pristojnega za državno statistiko.

which roughly translates to:
Borders of statistical regions are defined by the statistical office of Slovenia

Meaning that it has no administrative role, only statistical, which are more accurately tagged with boundary=census, same way as the 2 larger statistical regions of Slovenia (East and West NUTS2 statistical regions).

This is why i adjusted the tags accordingly (osmcha)

Re: Strange Admin Boundary in Slovenia

Your data collector seems to have finished with Slovenia - https://wambachers-osm.website/boundaries/

It looks a bit weird ti have so many admin_level 8 (212 municipalities) immediately under the country-level (admin_level 2), but this is what we have now.
Relevant part of the constitution: https://www.us-rs.si/en/about-the-court … s-138-145/

There are ongoing projects to introduce intermediary level with 8-14 regions, but that is not done yet.
Some description in english can be seen in https://aer.eu/regionalisation-slovenia … l-ror2017/

We have reserved admin_level=4 for these new regions, as described on:
- https://wiki.openstreetmap.org/wiki/Tag … _countries
- https://wiki.openstreetmap.org/wiki/Wik … evel_.3D_4

Yes, it is as it is - but this may change sometimes.

From my point of view it's important, that it's correct smile

Before that fix i could not deliver all admin boundaries of SVN to my users. Some Cities were missing. Of course only those which are mapped in OSM.

Thanks

Re: Strange Admin Boundary in Slovenia

BTW, Your tool could be improved to show the count of immediate sub-elements of a certain element instead of only admin_level. Eg it now shows "Slovenia (2)" but it could show "Slovenia (2) [212]" to show the number of municipalities. This is not a problem with fewer sub-elements, which can easily be counted by users, but so many don't even fit on a normal screen at once.

Good idea but no easy job. Will add it to my todo list.

Re: Strange Admin Boundary in Slovenia

The current (not yet accepted!) proposal for the interim administrative level (admin_level=4) contains
- 10 regions with multiple municipalities
- 2 regions containing just largest two city municipalities (Ljubljana & Maribor)

Almost like Germany: we got 13 States (Bundesland) and 3 Big Cities (Berlin, Hamburg, Bremen) also called Stadtstaat/City State".

All of them have the identical political rights and therefor all got Al4, of course.

Would like to have the same in Slovenia, but it's your country.

btw: My Boundaries Map service is down but should go online in 3-4 days. Yes, that was a really big crash sad
