Remember the little ads in the back of Popular Mechanics, Mechanix Illustrated and so forth offering to SELL western (or was it Canadian?) land for $20/sq mi? Getting just a photo for $20/sq km doesn't seem like such a bargain by comparison...not that this particular land was ever for sale anyway.

On a more serious note, I wonder if they'd let you order 2 photos of the same 50 km**2 taken maybe 5-10 seconds apart (the camera is moving 5 mi/sec), for the price of a single 100 km**2 one. The stereo-photo 3D aspect of it, and maybe getting lucky detecting movement, is more useful than additional resolution or coverage of extra empty desert, IMHO.

The more angles of view, the merrier. We often have a pretty good idea of what the base looks like from overhead, and the side view from Tikaboo. From other angles would be interesting. From a sat, you don't want to get TOO far from overhead, or the distance increases, the resolution decreases, and the number of square km covered by the camera increases. But I'd still advise giving up a little resolution in exchange for a little different viewing angle whenever possible.
