But a map is (this might have to be looked at for the individual case)
not only a work but can constitute a database at the same time. If you
are able to reconstruct a database with substantial parts of the
original database by re-engineering if from the map, you must admit
that the database somehow still was in the map. Otherwise you could
simply create a SVG-Map, publish it under PD, recompile the db from
the svg and you would have circumvented the license.
