Tree height is the vertical distance between the base of the tree and the highest sprig at the top of the tree. The base of the tree is measured for both height and girth as being the elevation at which the pith of the tree intersects the ground surface beneath, or "where the acorn sprouted." On a slope this is considered as halfway between the ground level at the upper and lower sides of the tree. … Web3.3. Validation of estimated and measured tree heights. To validate the method, we compared two different methods of measuring tree height. The first method was using laser distance metre and the second was with the algorithm. In total, 53 ground-measured heights were taken. Tree heights in the test area ranged from 1.20 m to 7.10 m.
