This declassified satellite image shows North Korea. It was captured on 23 August 1965 by a KH-4A CORONA reconnaissance satellite, as part of mission 1023.

The ground sample distance listed for this scene is 2.5 m. That is the size of one pixel on the ground, not the smallest object that can be picked out in the image.
