Development of a photogrammetric method of measuring tree taper outside bark

Abstract

A photogrammetric method is presented for measuring tree diameters outside bark using calibrated control ground-based digital photographs. The method was designed to rapidly collect tree taper information from subject trees for the development of tree taper equations. Software that is commercially available, but designed for a different purpose, can be readily adapted for use in this task. This paper presents the methods and procedures developed by the author.
