 This study investigates the feasibility of using terrestrial laser scanning, TLS, for forest inventory and above-ground biomass, AGB, estimation in a tropical forest in Malaysia. The results show that TLS can provide accurate estimates of tree diameter, height, and AGB with an R2 value of 0.98 and IMSE of 0.08 megagrams. This article was offered by Solomon M.B.N.A., Yusuf A.
