frankly speaking, to monitor your surroundings, you need your own personal satellite.

anybody remembers "behind enemy lines"? where the navy guys illegally take control of the satellite for a split minute to get owen wilson's location.

legally it would cost thousands, if not millions. and still would not be available.

2-3 hours to circle the earth, can you imagine the speed if they really did?
fastest planes take 15 hrs to reach India from US.
errr... imaging satellites orbit in LEO which is anywhere between 400 to 600 miles above earth. Communication satellites are parked in GSO as they need to be over the same location 24 hrs a day. Imagine the size of optics you need to get 1 meter resolution from a distance of 36,000 KM!!
Planes fly under mach 1 where as satellites orbit at almost escape velocity, so it takes only 2 - 3 hours to orbit earth once from LEO. That same time increases to 24 hrs from GSO.

Just float a camera tied to a tethered helium baloon and voila, you have your own personal imaging satellite with live feed to boot!
All google earth images are not satellite images. They are a mix of planes, hot air baloons and satellite images. You can know where an image has come from by looking at the resolution.
