Google Earth's New Satellites

Rambo Tribble writes "The BBC provides some insights into the next generation satellites being built for Google by contractor DigitalGlobe in Colorado. The resolution of these satellites' cameras is sufficient to resolve objects that are only 25cm wide. Unfortunately, the public will be allowed only half that image quality, the best being reserved for the U.S. military. 'The light comes in through a barrel structure, pointed at the Earth, and is bounced around by a series of mirrors, before being focused onto a CCD sensor. The big difference – apart from the size – between this and a typical handheld digital camera, is that the spacecraft will not just take snapshots but continuous images along thin strips of land or sea.'"

Continuous Image

[bondsbw]

What, pray tell, is a "continuous image" and how is it not a series of snapshots?

Is this like a video (which is seemingly continuous over time, made by sequencing snapshots) or like a panoramic image (which is continuous over space, made by processing/overlaying snapshots)?

But it probably gets Google the sats it needs for free.

If google can build it, but only the military can use the full resolution, it sounds like google is probably getting huge piles of money from the US Military.
