Even the private for profit space cameras are focused (pun intended) on land. High resolution systems are low altitude and need very specific orbits. Moving them would not be easy if at all possible. I have some experience designing systems to track submerged subs on a global basis. It isn't easy even when you know their port of departure. The ocean is mighty big and it all looks very similar.
You obviously have expertise in this & I have none Yanche....BUT....It's my understanding that these satellites fly orbits around the entire earth & couldn't we just re-program the cameras to give us a view of any spot on earth that they fly over?
How about the geosynchronous satellites we have that stay above the same patch of ground 24/7? (I know they are further out but are you sure that they have no visual capability?)
The layman's explanation of satellite orbits is here (http://marine.rutgers.edu/mrs/education ... bits2.html). IF you could have a camera system with sufficient resolution the non geosynchronous orbits can not observe one spot on earth continuously. Geosynchronous satellites stay in one place but they are way to far away to have cameras with sufficient resolution. The bigger problem is where do you look. Think of having to point your high resolution telephoto camera lens up into the heavens and find a specific star (pirate ship), but you don't know where the star is. Impossible. It likely the P3 Orion (http://en.wikipedia.org/wiki/P-3_Orion) that is tracking the pirates got considerable help in where to look from the ship that was boarded.
