Canopy height estimation using drone-based RGB images
Smart Agricultural Technology, 2023 Canopy height is an important crop biophysical parameter. It provides information about the crop growth as well as act as an input parameter for biomass and crop yield models. Considering the importance of this parameter, a novel semi-automatic canopy height estimation model has been developed which can work with both georeferenced or non-georeferenced

Under-Canopy UAV Laser Scanning Providing Canopy Height and Stem Volume Accurately [PDF]
Forests, 2021 The automation of forest field reference data collection has been an intensive research objective for laser scanning scientists ever since the invention of terrestrial laser scanning more than two decades ago. In this study, we demonstrated that an under-canopy UAV laser scanning system utilizing a rotating laser scanner can alone provide accurate ...

Large-eddy simulations of surface roughness parameter sensitivity to canopy-structure characteristics [PDF]
Biogeosciences, 2015 Surface roughness parameters, namely the roughness length and displacement height, are an integral input used to model surface fluxes. However, most models assume these parameters to be a fixed property of plant functional type and disregard the ...

Salinity‐induced limits to mangrove canopy height
Global Ecology and Biogeography, 2023 AbstractAimMangrove canopy height is a key metric to assess tidal forests' resilience in the face of climate change. In terrestrial forests, tree height is primarily determined by water availability, plant hydraulic design, and disturbance regime.
