Hi Carsten and Janko,

what about collecting German/European data from free sources
updated by other sources and publish them? It's no problem to
find server space, either here or on freegis-server (hi Jan).

I already started a page with URL collections:
http://www.geog.uni-hannover.de/phygeo/geodaten.html

Especially free vector data would be interesting. Maybe we can
partly automate the error checks and updates. 

I think we have access to VMAP Level 0 data (DCW stuff), probably
this could be updated somehow. Line matching algorithm should
be available somewhere.

Being very interested to participate,

 Markus
