I'm well familiar with reading French - thanks for the pointer !
Apparently these use terms are quite different from those on the EEA
site. This really looks like we should incorporate French CORINE data
into our collection of land cover data for the World Scenery. I'll be
preparing an appropriate setup.

The full license text is a bit more precise about 'similar'
4.b) "You may distribute, publicly display, publicly perform, or
publicly digitally perform a Derivative Work only under the terms of
this License, a later version of this License with the same License
Elements as this License, or a Creative Commons iCommons license that
contains the same License Elements as this License".

To my understanding (as well as the understanding of quite a few OSMers
to whom I've been talking about this issue) this doesn't permit to
distribute OSM-derived Scenery under the GPL. On the other hand, some
of the content which makes it into our Scenery is licensed under the
GPL.

Cheers,
        Martin.
