Abstract
This paper discusses the various formulas in use for the computation of tree heights from parallax measurements in aerial photographs. The errors in the computed tree heights, caused by the various error sources, are derived for three different cameras and four flying heights. The results of experiments are given and conclusions are drawn on the choice of formula and camera format and the accuracy that can be obtained in practice.Keywords
