Look at http://maspserver.sara.nl , under World Maps. It has eight 
detailed world maps (elevation, satellite, land use) at 30 seconds 
resolution (1 km at the equator, 21600*10800 cells). They are from NASA, 
NOAA and others and are all in the public domain. I resampled and 
retiled them to GeoTIFF, as described in yesterday's posting
If you want to set up a demo site with explanations how to do this in 
MapServer, I'll be happy to assist.
