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 ...

The Mosque Cluster at Gedi

The Gedi mosques are a group of religious structures located in the heart of ancient Swahili city of Gedi, also known as Gede. Gedi was likely occupied between the 11th and 17th centuries CE, and was a typical Swahili "stone town" located on the East African coast in modern Kenya. The ruins of Gedi include a walled town and its suburbs.
