ESTIMATING TREE CANOPY HEIGHT IN DENSELY FOREST-COVERED MOUNTAINOUS AREAS USING GEDI SPACEBORNE FULL-WAVEFORM DATA [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
Tree canopy height is an important parameter for estimating forest carbon stock, and mountainous areas with dense vegetation cover are the main distribution areas of trees, so it is important to accurately measure the forest canopy height in mountainous ...

A Framework for Improving Wall-to-Wall Canopy Height Mapping by Integrating GEDI LiDAR

open access: yesRemote Sensing, 2022
Spatially continuous canopy height is a vital input for modeling forest structures and functioning. The global ecosystem dynamics investigation (GEDI) waveform can penetrate a canopy to precisely find the ground and measure canopy height, but it is ...

Modeling tree canopy height using machine learning over mixed vegetation landscapes

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2021
Although the random forest algorithm has been widely applied to remotely sensed data to predict characteristics of forests, such as tree canopy height, the effect of spatial non-stationarity in the modeling process is oftentimes neglected.

Large-eddy simulations of surface roughness parameter sensitivity to canopy-structure characteristics [PDF]

open access: yesBiogeosciences, 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 ...

Canopy Height Estimation Using Sentinel Series Images through Machine Learning Models in a Mangrove Forest

open access: yesRemote Sensing, 2020
Canopy height serves as a good indicator of forest carbon content. Remote sensing-based direct estimations of canopy height are usually based on Light Detection and Ranging (LiDAR) or Synthetic Aperture Radar (SAR) interferometric data.
