General comments
Total tree height is defined to be the perpendicular distance between the ground level and the level of the top of a tree. In contrast tree length is the distance between the stem foot and the top along the stem axis. Obviously tree height and tree length are identical as long as the tree is growing vertically. For oblique trees, the difference between height and length becomes relevant and length is larger than tree height, depending on the inclination angle.
Measurement of tree height
A direct measurement of tree height (e.g. by means of a pole) is only feasible for relatively small trees and restricted to the assessment of regeneration or younger plantations. More common is the estimation of tree height based on the trigonometric principle or the geometric principle. Many different Category:Measurement devices are available, while most of the modern ones calculate tree height based on measured distances and angles.
