Via HelpScout, Poland released addresses (and some other data) in July:

http://codgik.gov.pl/index.php/darmowe-dane/prg.html

License reference is here but it's a pointer to the authorizing law--I think we'll need a native speaker to confirm. Looks promising, though. I've reached out to a Polish acquaintance who works on open data for his thoughts.

I was referred to Magdalena Siwanowicz, who generously contributed the following analysis. Note that her four-point division mirrors the link structure on http://codgik.gov.pl/index.php/darmowe-dane.html. Address points are contained within the first item/link. I think we're :+1:

Hello Tom,

Sorry for the late replay, but I had to check everything :)

Since July of this year, four datasets under this link http://codgik.gov.pl/index.php/darmowe-dane.html concerning geodetic and cartographic data were released free of charge and you can download the data - for sure it's allowed.

In accordance with the article 40a paragraph 2 point 1 of the Law on Geodesy and Cartography of 17 May1989 downloading data free of charge concern only four datasets:

1. the state register of boundaries and surface units of territorial division of the country
2. the state register of geographical names
3. general geographical objects contained in the database
4. concerned with the digital terrain model of the grid interval of at least 100 m The Centre of Geodetic and Cartographic Documentation on their website doesn't have information about licenses of the data. It's a quite often situation that public institutions forget that they should educate their users. All the time we are postulating that citizens should know what kind of rights they posses in relation to public data, because the lack of knowledge can hinder re-using it.

In my opinion dataset in points 1-4 from this website http://codgik.gov.pl/index.php/darmowe-dane.html is public information and can be re-used by all users freely and without any legal restrictions and can be used for any purpose, including business.

Good luck with your project! :)

Cheers,

Magda

Generally not everything considered "public information" by Polish law is freely redistributable, but address data is not covered by any of the exceptions in the "Law on Geodesy and Cartography" mentioned earlier and there is no indication of any restrictions anywhere on the CODGiK site or elsewhere that I've seen -- bip.codgik.gov.pl is where such restrictions should be documented if there were any (such as attribution or disclaimers of liability)

As Paweł Marynowski mentioned on OSM's talk-pl list, the quality of this data isn't great. There are many duplicate addresses, major inconsistencies in notation and some data that is just incorrect. Many municipalities publish their address data through punktyadresowe.pl which tends to have better quality. However there is no straightforward API to that site at the moment, there are still inconsistencies between different areas, and the licensing differs by municipality (the licensing requirements are limited by law and are pretty much compatible with CC-BY but most of the time not with CC0). OpenStreetMap is probably the best source where it has coverage (some 60-70% of the country at this time).

@balrog-kun thanks! Sounds like we should be creating sources for punktyadresowe.pl as well. Duplicate records aren't necessarily a big problem, but bad ones are. Do you have a link to Marynowski's email?

[balrog-kun]

Sorry, I just realised that was on an internal list, not talk-pl, in response to a query by Dietmar Seifert pointing to this issue.

[sbma44]

@balrog-kun ah, that's a shame. Do you think he might be convinced to share his perspective on this ticket?

Stale and we have poland now!
