Is there any articles establishing authentic and easy methods by which form factor of the tree bole can be measured using height, DBH or sectional diameter? Pls provide with citations.

Form factor is ratio of tree real volume to volume of one geometrical form such as cylinder. Form factor is one method for harmony and relation between tree form and volume. Form factor is calculable for all of trees (stems and branches) and/ or for tree stem. You may refer to forestry books like Avery & Burkhart (1994), Philip (1994), Van Laar and Acka (1997) and many others.

This estimator could be useful in forest inventories for species which do not express
significant butt swell, and could obviate the need for specific volume equatio
