This study investigated the efficacy of fusing simulated Global Ecosystem Dynamics Investigation (GEDI) lidar data with TanDEM-X (TDX) single-polarized InSAR data for the estimation of forest structure over a coniferous Forest — Teakettle Experimental Forest (TEF). Simulated GEDI canopy heights were used to constrain the unknown parameter of a widely-used SAR scattering model — Random Volume over...
Despite substantial policy attention, tropical forests in Southeast Asian region are releasing large amount of carbon to the atmosphere due to accelerating deforestation. Accurately determining forest statistics and characterizing aboveground forest carbon stocks (AFCSs) are always challenging in the region. In order to develop more accurate estimates of AFCS, the present study collected airborne...
Previous work has shown the ability of waveform LiDAR sensors to accurately describe various land cover types [1] and biomass estimates made in the field [2]. What is lacking, however, is a way to describe the different structural components that are embedded in the digitized backscattered energy from the LiDAR pulse. This study aims to extract structural components from waveform LiDAR data in terms...
Laser altimeter systems provide an accurate measurement of canopy height, the vertical structure of vegetation and the aboveground biomass (AGB). Airborne discrete return LiDAR (Light Detection and Ranging) was used operationally in many cases and some regions; spaceborne large footprint LiDAR (ICESat GLAS) has acquired over 250 million LiDAR observations over forest regions globally. The ICESat GLAS...
