[Mapserver-users] Hunting for global data

[Tyler Mitchell]

I'm looking for any good global-scale datasets to show off MapServer's 
capabilities. 
The first thing I started looking for was a DEM or elevation image but 
everything I'm finding is in some obscure format or another.  Anyone got 
gtopo in a more readily usable format and, ideally, seamless?
I'm also interested in a any other global datasets - countries, 
hydrography, etc. that others are using.

Any ideas?
