Tree height prediction in Brazilian Khaya ivorensis stands [PDF]

open access: yesBosque, 2018
 Tree height measurement is one of the most difficult activities in forest inventory data gathering, although it is a fundamental variable to support forest management, since it is an input for modelling growth and yield. To overcome this obstacle and ensure that the heights of trees are estimated accurately, hypsometric relationships are used ...
