[NetBehaviour] How Google Earth [Really] Works.

How Google Earth [Really] Works.

After reading an article called "How Google Earth Works" on the 
generally great site HowStuffWorks.com, it became apparent that the 
article was more of a "how cool it is" and "here’s how to use it" than a 
"how Google Earth [really] works."

So I thought there might be some interest, and despite some valid 
intellectual property concerns, here we are, with "part one" of 
explaining how at least part of Google Earth works.

Keep in mind, those IP issues are real. Keyhole (now known as Google 
Earth) was attacked once already with claims that they copied someone 
else’s inferior (IMO) technology. The suit was completely dismissed by a 
judge, but only after many years of pain. Still, it highlights one 
problem of even talking about this stuff. Anything one says could be 
fodder for some troll to claim he invented what you did because it 
"sounds similar." The judge in the Skyline v. Google case understood 
that "sounding similar" is not enough to prove infringement. Not all 
judges do.
