- of a vertical aerial photograph is directly proportional to camera focal length (image distance) and inversely proportional to flying height above ground level (object distance). • For example, a vertical aerial photograph is obtained over flat terrain with a 12-in. focal-length camera lens from an altitude of 60,000 ft AGL.

- Parallax Height Measurement This is the most used method of measuring heights on air photos. There are many forms of the parallax equations. Avery and Berlin give one; Paine in his book lists three: 1) for mountainous terrain; 2) for level terrain; and, 3) the short cut equation. What I will give here is the basic form of the equation: Ho = Ha x dP
