Using Multi-Spectral UAV Imagery to Extract Tree Crop Structural Properties and Assess Pruning Effects [PDF]
Unmanned aerial vehicles (UAV) provide an unprecedented capacity to monitor the development and dynamics of tree growth and structure through time. It is generally thought that the pruning of tree crops encourages new growth, has a positive effect on ...

New Insights into Tree Height Distribution Based on Mixed Effects Univariate Diffusion Processes. [PDF]
The aim of this paper is twofold: to introduce the mathematics of stochastic differential equations (SDEs) for forest dynamics modeling and to describe how such a model can be applied to aid our understanding of tree height distribution corresponding to ...

FOREST RESOURCE MEASUREMENTS BY COMBINATION OF TERRESTRIAL LASER SCANNING AND DRONE USE [PDF]
Using terrestrial laser scanning (TLS), forest attributes such as diameter at breast height (DBH) and tree location can be measured accurately. However, due to low penetration of laser pulses to tree tops, tree height measurements are typically ...

Tree height and tropical forest biomass estimation [PDF]
Tropical forests account for approximately half of above-ground carbon stored in global vegetation. However, uncertainties in tropical forest carbon stocks remain high because it is costly and laborious to quantify standing carbon stocks.
