Considering the Produced Work - Guideline: Is the result of Osm2city  
in your opinion a product or a derived database?

If it is a product, then you can choose your own license, but you  
still have comply with the conditions of No. 4.3. ODbL .

If it is a derived database then you have to comply especially with  
the conditions of No. 4.2 and 4.4 ODbL (but not only). Your derived  
database will still be under ODbL.
If it's a derived database , then it also raises the question of  
whether ODbL (Open Data License) and GPL (Free Software/Open Source  
License) are compatible with each other, No. 4.4 a. iii. ODbL.

> I'm using a program called Osm2city [1] that generates scenery for the

> impossible, to get anything packaged with it, that's not GPL2.
> So my question: May I release the results under the GPL2 (if needed with

> A list of this work is available on our wiki[3].
> Example results can be downloaded as well from the wiki page[3].
