The impact of geolocation uncertainty on GEDI tropical forest canopy height estimation and change monitoring

open access: yes, 2021
The Global Ecosystem Dynamics Investigation (GEDI) LiDAR provides new spaceborne vegetation canopy structural information including relative canopy height products defined with respect to 25 m diameter footprints. The GEDI geolocation requirement is that

Forest structure dependency analysis of L-band SAR backscatter [PDF]

open access: yesPeerJ, 2020
Forest structure plays an important role in forest biomass inversion using synthetic aperture radar (SAR) backscatter. Synthetic aperture radar (SAR) sensors with long-wavelength have the potentiality to provide reliable and timely forest biomass ...

Tropical forest canopy height estimation from combined polarimetric SAR and LiDAR using machine-learning

open access: yesIsprs Journal of Photogrammetry and Remote Sensing, 2021
Forest height is an important forest biophysical parameter which is used to derive important information about forest ecosystems, such as forest above ground biomass. In this paper, the potential of combining Polarimetric Synthetic Aperture Radar (PolSAR)

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.

Landsat-Scale Regional Forest Canopy Height Mapping Using ICESat-2 Along-Track Heights: Case Study of Eastern Texas

open access: yesRemote Sensing, 2022
Spaceborne profiling lidar missions such as the Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) are collecting direct elevation measurements, supporting the retrieval of vegetation attributes such as canopy height that are crucial in forest carbon ...

An Improved Generalized Hierarchical Estimation Framework with Geostatistics for Mapping Forest Parameters and Its Uncertainty: A Case Study of Forest Canopy Height

open access: yesRemote Sensing, 2022
Forest canopy height is an essential parameter in estimating forest aboveground biomass (AGB), growing stock volume (GSV), and carbon storage, and it can provide necessary information in forest management activities.

Canopy Density and Roughness Differentiate Resistance of a Tropical Dry Forest to Major Hurricane Damage

open access: yesRemote Sensing, 2021
Tropical dry forest is vulnerable to increased climate variability with more frequent and severe storms. Studies of hurricane impact on tropical dry forest often focused on individual tree traits. How trees in tropical dry forests work together to combat

A Comparison of Machine Learning and Geostatistical Approaches for Mapping Forest Canopy Height over the Southeastern US Using ICESat-2

open access: yesRemote Sensing, 2022
The availability of canopy height information in the Ice, Cloud, and Land Elevation Satellite-2’s (ICESat-2’s) land and vegetation product, or ATL08, presents opportunities for developing full-coverage products over broad spatial scales. The primary goal

New global map of forest canopy height [PDF]

open access: yesEos, Transactions American Geophysical Union, 2012
Just how tall are forests around the world? A new global map shows forest canopy height at 1‐kilometer spatial resolution. Simard et al. used satellite data from the Geoscience Laser Altimeter System aboard the Ice, Cloud, and land Elevation Satellite (ICESat) to create a global map of the height of the forest canopy.

Forest drought resistance distinguished by canopy height

open access: yesEnvironmental Research Letters, 2018
How are the survival and growth of trees under severe drought affected by their size? While some studies have shown that large trees are more vulnerable to drought than smaller trees, others found that small trees are the more vulnerable. We explored the potential relationships between canopy height and forest responses to drought indicated by tree ...
