(3) Panoramic photos are taken by a camera system with a moving lens or
a rotating prism which sweeps or scans the area of interest, from side to
side, across the line of flight of the aircraft. This sweep produces a near
vertical view in the center of the photo, with either high or low obliques
on either side, depending on the type of camera used. The film size can be
2.25 to 4.5 inches wide, and the frame can be anywhere from 9 to 75 inches
long. This allows the system to photograph a large area on either side of
the aircraft's line of flight in a single pass.
There are two types of
panoramic photos:
(a) Low panoramic photos are obtained from a camera that scans a 180
degree arc across the flight path resulting in a strip showing terrain from
directly under the aircraft to the horizon on both sides of the flightpath
(Figure 1-7).
