Title: I can see my house from here!
Post by: Iceman on June 11, 2005, 12:11:30 am: Nasa World Wind. Check it out, real time satellite imaging using NASA satellites. A buddy of mine showed it to me, and I'm DL'ing it now to try it out.

Figured you'd all enjoy it.

----------------------------------------

Can I see the world in real-time?

This just isn't practical and won't be possible anytime soon. To do this requires a network of satellites dedicated to covering the earth. Just to provide as much detail as the base layers WorldWind loads first, the camera resolution on each one has to total about 100 megapixels. Perhaps the military has such a network, but it is certainly off-limits to anyone else. The images have to be received on the ground and processed. Then they all have to be combined where they overlap and corrected for the distortion caused by the earth's curvature. Finally after compressing the imagery from gigabytes down to several hundred megabytes, a server has to send it out to everyone. This requires an enormous amount of bandwidth for the server. Even if that weren't a problem, the internet connection for the majority of high-speed users is still too slow for more than about one update every hour.

So with Onstar, yahoo, and other people doing nifty things with maps, why not with sat imagery?

I believe that was the name of the comapny that Google bought it from.
