A Tree-Crown Profile Projector
Abstract:When classifying trees according to vigor, dominance, and maturity, foresters often find it desirable to measure vertical and lateral crown profiles. Although vertical profiles can readily be charted, the true shape of a lateral profile cannot easily be determined by an observer on the ground because angle of vision and perspective cause distortion. The degree of distortion depends on the height of the tree and the distance of the observer from the tree, and is more pronounced in the upper part of the profile.
