KML 2.2 beta looks like it contains the ability to view spherical panoramas in Google Earth:
Looks like our Google Earth Panorama viewer (pictured above) may of had its day. Soon as we get a working version we will put up more details and a movie.
Thanks go to Karl for emailing us the tip…
Google have just bought Panoramio too (see the GE blog), so I wouldn’t be surprised to see the Panoramio material appearing in this new form.
I’m not sure if you’ve seen this tool yet, but Frank Taylor of Google Earth Blog showed me the Space Navigator yesterday at GDD07 that allows a camera view as part of the navigational controls. Check out his blog for more info.
I also posted more on San Jose GDD07 on my blog and contributed to Ogle Earth for a summary of the keynote.
