Forest Canopy Height Estimation Using Multiplatform Remote Sensing Dataset [PDF]

open access: yesJournal of Sensors, 2018
Recently, numerous studies have attempted to determine forest height using remote sensing techniques that not only have the benefits of fast data acquisition, processing, and analysis but are also cost-effective. However, if there was insufficient data to apply the latest remote sensing techniques, we need to consider many kinds of datasets as possible.

Stereo RADARSAT data for canopy height in Brazilian forests

open access: yesCanadian Journal of Remote Sensing, 2000
Cet article demontre la possibilite d'utiliser les images stereoscopiques de RADARSAT pour interpreter et mesurer certaines caracteristiques de la foret pluviale tropicale du Bresil. A partir d'un couple stereoscopique d'images en mode fin de RADARSAT, on interprete qualitativement et on mesure quantitativement les limites de coupes, la couverture ...

On the Estimation of Forest Vertical Structure From Multibaseline Polarimetric SAR Data [PDF]

open access: yes, 2012
Forest characterization and biomass estimation by means of remote sensing systems are nowadays “hot topics” within the remote sensing community, given their importance in the terrestrial carbon budget. In fact, forest vertical structure is a key variable

Canopy height estimation with TanDEM-X in temperate and boreal forests

open access: yesInternational Journal of Applied Earth Observation and Geoinformation, 2019
Abstract Various semi-empirical models for linking PolInSAR data (polarimetric synthetic aperture radar interferometry) to canopy height of vegetation exist. However, only single-polarized data were used during the TanDEM-X mission in order to create a global digital elevation model (DEM).

Impacts of Water Stress on Forest Recovery and Its Interaction with Canopy Height [PDF]

open access: yesInternational Journal of Environmental Research and Public Health, 2018
Global climate change is leading to an increase in the frequency, intensity, and duration of drought events, which can affect the functioning of forest ecosystems. Because human activities such as afforestation and forest attributes such as canopy height may exhibit considerable spatial differences, such differences may alter the recovery paths of ...

Elevation and Distribution of Freshwater and Sewage Canals Regulate Canopy Structure and Differentiate Hurricane Damages to a Basin Mangrove Forest

open access: yesRemote Sensing, 2021
The coastal mangrove forest bears important ecosystem functions and services, including the protection of shorelines and coastal communities. While coastal mangroves often suffer severe damage during storms, understanding the vulnerability and resistance

Plant Species Richness is Associated with Canopy Height and Topography in a Neotropical Forest [PDF]

open access: yesRemote Sensing, 2012
Most plant species are non-randomly distributed across environmental gradients in light, water, and nutrients. In tropical forests, these gradients result from biophysical processes related to the structure of the canopy and terrain, but how does species richness in tropical forests vary over such gradients, and can remote sensing capture this ...

Quantifying mangrove canopy regrowth and recovery after Hurricane Irma with large-scale repeat airborne lidar in the Florida Everglades

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2022
Hurricane Irma caused significant damages to mangrove forested wetlands in south Florida, including defoliation, tree snapping, and uprooting. Previous studies have used optical satellite imagery to estimate large-scale forest disturbance and resilience ...

Capability of GLAS/ICESat Data to Estimate Forest Canopy Height and Volume in Mountainous Forests of Iran [PDF]

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2015
The importance of measuring forest biophysical properties for ecosystem health monitoring and forest management encourages researchers to find precise, yet low-cost methods especially in mountainous and large areas. In the present study, geoscience laser altimeter system (GLAS) on board Ice, Cloud, and land Elevation Satellite (ICESat) was used to ...

Light-related variation in sapling architecture of three shade-tolerant tree species of the Mexican rain forest [PDF]

open access: yes, 2008
The crown architecture of three shade-tolerant tree species (two subcanopy and one mid-canopy) was analyzed in relation to the light regime of the forest understorey.
