OMG!
This has to be one of the greatest things I've seen come out of Google since Earth! Congratulations, the scale of it is enormous.
I'll just put in some slight complaints tho despite them not detracting from the pure Awesome-ness of it all -
-Their panoramic camera is a bit susceptible to exposure blowouts or underexposures, and the occasional large lens flare and other photographic nasties (hundreds of thousands of pics you'd expect this).
-Aside from the above, bad focusing can make a mess of some shots.
-After walking around New York and Frisco for about five or ten minutes, my system began to slow down, IE reported it was taking up 150mb ram!
-You get occasional black semi-circling at the top and bottom edges as the camera goes up or down hill. They could have filled in some photo areas with blue for the sky and maybe grey for the ground instead.
But as I said, the system is frickin amazing! Boo and Hiss to those who say it's been done before, congrats to Google for making it happen on a massive scale.
P.S. WOO-YAY More dirty billboards! More dirty billboards! Somebody catalogue them all on a site somewhere! Thx Ian.
