I'm not sure where the images were found, but the original images are ~100 x's larger. I'm sure they will use an appropriate size/resolution that best suits the medium. Full resolution could not really be used on line. Full res could however be used on a viewer in a sales office.

They will probably be seen soon as an interactive part of the aura website and/or sales centre.

The images were not taken with a wide angle but were made up of multiple images. They are meant to be seen in a viewer that adjusts for the 180 degree pan.

altitude The images were definitely taken from 750'. The views will of course be far more impressive with the naked eye. Have you ever taken a photo of a mountain? Can never come close to the real thing.
