World Wind

[KanyonKris]

Played around with a program called World Wind last night. Pretty cool - kind of like Keyhole. Starts with a view of the globe you can pan and zoom. Multiple data sets to choose from. As you zoom closer more detailed tiles are loaded from servers on the Internet. Elevation data is included so you can view in 3D (with adjustable exageration). Not real useful for planing routes and such, but sure a cool toy to play with. Maybe some of these data sets could be used by TF?

Yep.  Worldwind was one of the ways I found out about the OnEarth server.  That is what it is using to get satellite images as well as elevation data.

When Worldwind was slashdot'ed, the onEarth server couldn't handle the load and was down for a time.

Not sure what other datasets you're referring to, but I haven't used it for a while, I suppose.
