Play around with truncating the URL. A clue is that there are zip files of DEMs there - so the whole thing was no doubt generated & rendered. Other views include the same dataset with clouds and ice - pretty stuff indeed!

There's a folder on there with a file named bryce.zip, which makes me uneasy - bryce is not open source. But it is shareware. Still, I'd rather get it from the developer. Hmmmm - but there's some kind of promotion right now where bryce7 pro can be had for free: the developer's site: http://www.daz3d.com/products/bryce/...what-is-bryce/ Looks like they usually separate into a free version, a better version that costs a little, and a pro version that costs more. Bryce is a rendering package, so that's a plausible pathway to the world map you link to.
