[GRASS5] Vector format request by company

[Martin Wegmann]

Hello, 

I received a message from ENAiKOON http://www.enaikoon.com. They are 
interested in using GRASS for their work but they have to import TeleAtlas 
http://www.teleatlas.com/homepage.jsp and Navtech 
http://www.btinternet.com/~navtech/ maps. 
Is anybody aware of these formats? Or does anybody now if it is possible to 
import them into GRASS?  

cheers Martin
