What about geosynchronous satellites. or aren't todays optics up to the
job?


Geosynchronous satellites are in orbits at altitudes of over 22,000 miles.
Even the best of optics will take more detailed pictures at 100,000 feet or
less.

22,300 miles to be exact. Comsat, before it was bought by Lockheed
Martin, was located at 22300 Satellite Drive.
