APPLICATIONS OF GEDI LIDAR FOR REMOTE SENSING OF FOREST STRUCTURE AND BIODIVERSITY INDICATORS
… a proxy. First, I introduce the application of GEDI lidar for differentiating between forest types by examining structural differences between native mangroves in Nigeria and an invasive palm species introduced to the delta. My findings indicate that even in short, coastal forests, GEDI is …

FUSING GEDI LIDAR AND TANDEM-X INSAR OBSERVATIONS FOR IMPROVED FOREST STRUCTURE AND BIOMASS MAPPING
… NASA’s Global Ecosystem Dynamics Investigation (GEDI) mission presents an unprecedented opportunity to advance current global biomass estimates. However, gaps are expected between GEDI’s ground tracks, requiring the development of fusion-based methodologies to contiguously map forest biomass at …

Measuring tropical forest disturbance and regrowth with spaceborne lidar
… The Global Ecosystem Dynamics Investigation (GEDI), a spaceborne lidar sensor, offers the opportunity to measure forest structure and carbon stocks at global scale, and is sensitive enough to capture subtle forest variation even under dense tropical canopies. However, it is computationally …

Diameter Estimation of Eucalyptus spp. Plantations in Southern Brazil Using Global Ecosystem Dynamics Investigation Data and Support Vector Regression
… the Global Ecosystems Dynamics Investigation (GEDI) provide an excellent opportunity to measure plantation forests over large areas. We focused our efforts on Eucalyptus in southern Brazil and used data from an industrial partner to investigate plantation metrics (height, diameter, volume, …

The Carbon Density and Species Diversity of Myanmar's Tropical Forests
… collected by NASA’s space-borne LiDAR sampler (GEDI). Using matching analyses, I find that terrain (elevation, slope, and aspect) and climatic attributes (including precipitation) are positively related to ACD, plateauing at higher values. ACD is negatively affected by anthropogenic factors, …

Remote Sensing Characterization of Ecosystem Structure and Functional Types to Inform on Biodiversity Conservation in the Lowland Chocó Rainforest
… ecosystem functioning are derived from PALSAR-2, GEDI and ECOSTRESS. An evaluation of remote sensing variables correspondence with land use classifications is also conducted. Ecosystem structure and functioning products developed at the local scale in previous chapters are validated in a regional …

A Deep Learning Study on the Retrieval of Forest Parameters from Spaceborne Earth Observation Sensors
The efficient and timely monitoring of forest dynamics is of paramount importance and requires accurate, high-resolution and time-tagged predictions at global scale. Despite numerous methodologies have been proposed in the literature, existing approaches often compromise on accuracy, resolution, …
