I would say that as far as GPS data goes the street maps of the world
would be pretty big.

openstreetmap.org is still a work in progress but their current db dumps
gzip down to 6.4GB. It was a while back that I noseyed around with it
but I do recall that it compressed well and was very large uncompressed.
Don't recall how many rows it contained.

I wonder what an almost complete world street map like google maps comes
in at?
