HI Till.

http://www.fugawi.de/TeleAtlas-Karten-Deutschland.html states that the data is in GDF format,...

Where? I only see them stating that they are in GMF format. Oh, wait, no...
The Germany map seems to be the TeleAtlas-multinet version (GDF format) while the European map CDs seem to be GMF.
Oh no, wait,...
Damn, those people at fugawi.de need to get this straight, the CD description says GMF, while the documents regarding the contained countries all say GDF. How is anyone going to understand what the CDs actually contain?
Oh well, they say those are TeleAtlas multinet, so according to TeleAtlas themselves, they should be in in both GDS-AS and GDS-AR formats.

Kim: Could you import those CDs into your system? Or actually write a conversion program that takes a user's CD and imports that?
