Subject: Re: SVG topo map of US ponies on Assateague Island
Vector based maps would be very nice, but how
about the simpler request of just a georeferenced
TIFF of the whole USA, or even whole continents
throughout the world. Does anybody know where
I can get those? I'd also like to get a single
georeferenced TIFF of each of the 50 states in the
US.
I'm surprised I have not run across these on the
web myself.
