Yes it is, but is it defendable? I mean could then anyone prove in
court that it is a "work resulting from" and not the Database itself?
It would take a few more steps (eg. arrange some inbetween maps to
lose the trace) to do it on purpose, I think.
For me this is more a question of using 'normal' tiles to make just
another map, and I don't see there's a way to prohibit it in ODbL.
