found an interesting website:
http://www.ertico.com/links/gdf/gdf.htm

Here you find the specifications on the GDF map data format which is used by Teleatlas together with some sample files and explanations.

If I understand that correctly, Teleatlas uses the gdf format and the specifications of that format are available at the website linked above. Why can't we use this data? AFAIK Teleatlas provides the most accurate map data...
