Is there a freely available (governmental?) heightmap (=elevation?) dataset for Kraków city (in Poland) with horizontal grid ~5m (or better) and vertical resolution ~ +/- 0.1m? Ideally, it would include building heights (i.e. not "ground level").

If you don't know one, at least do you know of some good open forum where I could ask such a question with some hope of getting an answer?

Sorry if that question doesn't use proper terms and/or is too unclear, or otherwise totally ridiculous; I'm totally unexperienced in GIS.

  • Maybe ask on (1) Geographic Information Systems Stack Exchange. You're probably looking for LIDAR data, which is sometimes available freely.

  • @scruss: done that already, someone there suggested that I ask here ;)

  • @scruss: hmmm, that seems to be a good direction: googling for LIDAR I found some pdf article apparently using such data, which then seems to suggest Polish term "lotniczy skaning laserowy", which again leads to e.g. some nice video. Now what remains is to find out how to get access to this data.

Wow, wow, wow, based on @scruss's hint, I maybe have found something; not exactly free, but really, really cheap (i.e. not "bussiness prices" but "average guy prices" apparently); only I must yet verify if the data is really good enough for me and what I think it is, but there are some samples. Without further ado, the links are:

http://codgik.gov.pl/index.php/zasob/numeryczne-dane-wysokosciowe.html - an overview of the available subtypes of data, and details on how to request them;

http://codgik.gov.pl/index.php/obsluga-klienta/oplaty-za-udostepnianie-materialow-fotogrametrycznych.html - pricing (seems 2-4zł per km2 IIUC, which seems totally approachable).

(Note: found based on information in a GUGiK video.)
