Jukka,

I have used mapserver to map directly from VMAP0 data in the past.  But it is
not necessarily all that efficient so if you want to do serious work I'd
encourage you to pull the parts you need out of VMAP0 in shapefile or some
other high performance format, build spatial indices, etc.

Indeed.  I don't quite have the zen of quoting for the windows command window
mastered yet.
