GIS on the web is going to hit a new level of awesome soon. I’ve been working on an entirely-written-in-Javascript 3D map for a bit now. It’s based on Closure Tools and NASA’s Worldwind and uses WebGL for hardware acceleration.

A few minutes ago, I just managed to get the tiled blue marble layer working. Here’s a screenshot of the results:

Or, if you have a WebGL enabled browser, take a look at the live demo (It’s buggy, click-to-drag doesn’t work well. Try out the mouse-scroll-wheel-zoom for some nifty tile disappearing and reappearing action based on the zoom level.) :

Lastly, if you’re a developer, take a look at the source on my github. I *heart* patches.
