I am looking for municipal-level administrative boundary data (NUTS 5) for Poland. Since it is public information, I thought the data would be readily available, but I can't seem to find it anywhere. I have checked the usual sources. GADM has data down to the county (powiat) level, and Natural Earth seems to only have data down to the provincial level. I have looked at many of the Polish government's sites, but while I can find plenty of GIS data viewers, I can't find a way to download the administrative boundary data I am interested in. To make matters more complicated, I would really like historic data, but I would settle for current NUTS 5 level data.
You might try contacting Francis Harvey, one of the Co-Directors of the MGIS program at the University of Minnesota. He does a lot of GIS research in Poland, and is probably very well aware of what is and is not publicly available.
NUTS 5 (gmina) is the most detailed level of administrative structure in Poland.
It's been a while since I left my homeland, but as far as I am aware it will not be possible to obtain such dataset for free.
For a quick overview have a look at geoportal.gov.pl - web map service of national mapping agency.
You might also post a question on Google Groups to get more up to date info or some pointers to where you could purchase this kind of data.
Unfortunately you have to purchase good quality data, i.e. here:
I have seen a post in polish at http://forum.cad.pl/mapa-powiatow-t72142.html. Where is suggested that you can get your data at specified link to sdi.geoportal.gov.pl. Data are in GML but you can convert it with Ogr2Ogr to anything you need. I do not know about licencing for that. Have a look.
You may also try to look around at http://www.openstreetmap.org/ as you can download .shp data from there (http://wiki.openstreetmap.org/wiki/Shapefiles#Download_shapefiles_of_OSM_data). But even if the data are available, the quality is doubtful.
Sadly, availability of GIS data in Poland is quite limited, not to mention free GIS data.
Not sure whether this question is still open, but you might want to check out the Eurostat website, which hosts some valuable information on the NUTS system including maps, metadata and shapefiles for download:
They also seem to have an archive section with older NUTS versions, but I haven't checked this out in detail yet.
Please check below link, it provides municipal (Gminy) level data for Poland
Last time I played with NUTS level data there was hardly anything publicly available below NUTS-2 or 3. Unless there has been a major break through in openness by European NMA in the last five years I'd guess you are out of luck. A quick google seems to confirm this (though as I don't speak Polish there may be sites out there I'm missing but I can't find equivalent for the UK)
