PRESENTATION

Carte de hauteur

A canopy height for French Guiana obtained using the data fusion of LiDAR, optical and other environmental datasets. The precision of the map by comparison to a high precision airborne LiDAR canopy height estimates was evaluated at around 3 m (mean canopy height of 30 m).
