Validation of the vertical canopy cover profile products derived from GEDI over selected forest sites

Science of Remote Sensing
Canopy cover (CC) quantifies the proportion of canopy materials projected vertically onto the ground surface. CC is a crucial canopy structural variable and is commonly used in many ecological and climatic models.

A modelling framework to estimate canopy height at local scale using optical and radar images paired with GEDI measurements in Mediterranean-like landscapes

International Journal of Digital Earth
The near-worldwide coverage of spaceborne LiDAR data from the GEDI offers unprecedented opportunities for mapping canopy height (CH). Notwithstanding the sensitivity of the GEDI to forests’ vertical structure, it provides sparse sampling measurements ...

From Spaceborne LiDAR to Local Calibration: GEDI’s Role in Forest Biomass Estimation

Remote Sensing
Forest ecosystems act as major carbon sinks, highlighting the need for the accurate estimation of aboveground biomass (AGB). The Global Ecosystem Dynamic Investigation (GEDI), a full-waveform spaceborne LiDAR system developed by NASA, provides detailed ...
