Archaeology Dictionary:
vertical aerial photograph
[De]
Photographic image taken from an aircraft or similar high-level elevated platform where the camera direction is at right angles to the ground beneath and the face of the film is more or less parallel to the ground surface. Vertical aerial photographs can be precisely scaled if the distance between the ground and the camera and the focal length of the camera's lens is known. Overlapping pairs of vertical aerial photographs allow stereoscopic viewing to create an optically realistic three-dimensional image. Compare oblique aerial photograph.
