I've spent a couple of hours looking through the links you posted. There are a lot of tantalizing clues about resolution, stated in one article as being 5” to 6” for visible light. Another article says radar can resolve 5’ or less and can actually resolve under ground to an unspecified extent. Yet another article talks about resolving plant types and detecting fire by way of spectral analysis ranging from visible to infra-red. I didn’t see a minimum resolution but the article spoke of resolving certain light types down to 400 nm. They claim 62-98% accuracy depending on the color of the item being examined. Wheat stubble was stated as most accurate.

Another whole element to this is the development of 3d imagery and of interpolating images of different views.

And yet another article said that there is a lot of remote imaging equipment that is *at least* as powerful as the Hubble, but aimed at the planet.

Teasing.


If the project I told you about is successful, I'm gonna get something in the medium format genre. I saw one reference to 16 MP back for a 6x7 cm format camera, but haven't found out the size of the CCD. My current steed is a cybershot 3.3 MP. I've done some tests of up to 12x18 prints and the quality is extraordinary overall. There is a tendency to drop off as the color approaches white or black, but the image is there, and the drop off is in the printing process. BTW, if anyone is interested, Costco will provide a 12x18” print for a mere $3 per copy. They do excellent work.

If bus speed is a limiting issue, I'm surprised that there aren’t dual imaging devices to accommodate for this failure.

Thanks again!
