Optical Dendrometers For Out-Of-Reach Diameters: A Conspectus And Some New Theory
Abstract:Three main classes of optical dendrometers are discussed: forks, calipers, and rangefinders. Noncoincident, nonmagnifying dendrometers have little promise. Some improved designs with promise are mentioned. A new exact theory for rangefinder-dendrometers is presented for the first time and is translated into a highspeed computer program converting instrument readings to tree volume, etc., in about a second. Field tests suggest rangefinder-dendrometer volumes will vary no more than ± 4 percent from individual-tree check estimates.
