Here's a google maps link to one of the charts mentioned, on Edwards Airforce Base:

Fascinating that there are air craft relics near the charts. I can only imagine that is part of the calibrating: so they can tell how large an aircraft is and what resolution they get for the size.

Indeed, plus one of the aircraft is one of only two remaining examples of the X-21 [0]. I suspect the other is also derelict on the range somewhere.

Can we derive the implied resolution of government satellites by the test charts?
