Abstract
  • This paper includes a literature review of the methodologies invoked to surmount difficulties inherent with aerial photograph mensuration. The synopsis of early achievements is followed by a more intensive examination of experimental studies of the last decade, particularly the work on controlled scale photography. This report on the pursuit of unbiased photo volume estimates culminates with a discussion of recent trials using the techniques of analytical stereoscopy. A Carto AP19O analytical stereoplotter linked to an IBM AT personal computer was used for precision camera orientation reconstruction at the moment of exposure, thereby removing many sources of bias. A trial photo cruise of a mature stand of Douglas-fir in Oregon's Coast Range indicates that it is possible, when using these mathematical solutions of parallax, to determine gross volumes to within five percent of ground-verified estimations.
