Accuracy of conventional computations in assessing volume of small diameter logs of hopea odorata

The accuracy of volumetric computation of small diameter logs based on mathematical formulae was evaluated. Plantation logs of 13-year-old Hopea odorata with diameter measurements of 20 to 30 cm were assessed using Huber’s, Smalian’s, Newton’s and truncated cone formulae. The reference volume of eac...
