Your inquiries were hostile in tone, and it seemed to me you were demanding proof rather than asking for information that genuinely interests you. I therefore decided to ignore you.
Since then, however, others have asked about the Spheron data. It amounts to more than 2 gb, but the images themselves are bitmaps, with meta data and a rendering engine so a viewer can pan around and get a rough sense of what it is visible from the points where the images were shot. I saved the bitmaps as jpegs, packed them into a zip file, and uploaded them to the FOA server:

You will have to manipulate the images in your viewer, but the material is there.
