[GRASSLIST:9412] Re: Reading and converting VMAP0

[Nick Cahill]

Just in case anyone else is in the same boat, I installed William  
Kyngesburye's gis libraries for Mac OSX, and these were able to  
convert vmap0 files to shapefiles successfully. I don't know why this  
didn't work with the library files installed by Lorenzo Moretti's  
installation of GRASS - but in any event, I'm happy.

It would be a big service for someone to convert all that data to  
shapefiles and make it available on the web. Is there an advantage to  
keeping it in the original VMAP0 format?
