This image of a multi-storey car park was taken from a tethered balloon in the eastern US. The image is reproduced by kind permission of Virginia Hanwick. The altitude from which the aerial image has been taken is clearly lower than would have been possible from an aircraft, but greater than could be achieved using a cherry-picker etc. The angle of view has been carefully chosen and the clarity of the image is excellent. Images of this nature reveal a lot of detail about a structure that is often difficult to obtain in other ways.
