Book Description
De procedure van de Duitser Hohenadl voor het bepalen van vormquotienten (afgeleid van diverse stamdiameters) en de boominhoud (ook afgeleid van stamdiameters op vastgestelde hoogtes) wordt behandeld. De procedure in gewijzigde vormen werd toegepast op gegevens van de Tsuga hetrophylla. De beschreven procedure blijkt ook voor andere boomsoorten toepasbaar

Book Description
Excerpt from Tree Form Quotients as Variables in Volume Estimation Altherr (1960) and Assmann (1970) identify an approximate 4 - percent underestimate of tree volume as calculated by Hohenadl's method. Five measurements failed to properly account for flare near the tree base. The underestimate can be corrected by using additional diameters measured at other proportions of tree height near the base of the tree. With nine diameters, tree volume can be estimated within 1 percent of volume estimates that use measurements every feet along the total tree stem (altherr The rationale of Hohenadl's method holds when additional proportional diameters are used to increase volume precision.
