Greetings, I am looking for a hi-res bump map of the entire earth's topography, undersea as well as on land. You know how in textbooks and such they show you those images of the terrain under the oceans and you can see the continental shelves, the mid-ocean ridges, the deep trenches; all that? I'd like to find a grayscale height map of those features.      To head off one misdirection right now I've found references to a site called "www.space-graphics.com" but it has been taken over by something called "PLMetro.Info". (And how does that happen that an address like that gets you to a site that has nothing to do with what you are looking for?) At any rate, I already have some of the maps from that old space-graphics.com site and they didn't have a below the ocean height map that I know of. -- Jeff in Arkansas
