Illustration of four promising technologies in the context of forest monitoring at different spatial scales. a Three-dimensional reconstruction of a Cameroonian tree from terrestrial LiDAR data (Nicolas Barbier, Jules Morel, and Pierre Ploton). b Three-dimensional reconstruction of a French Guianan landscape from aerial LiDAR data in the Nouragues reserve (Maxime Réjou-Méchain). c Very high resolution optical imagery from a Cameroonian landscape showing contrasted spectral signature and texture from different forest types (Nicolas Barbier). d Image derived from ALOS L-Band Radar data showing a Cameroonian forest-savanna mosaic at 12.5-m resolution (Stéphane Mermoz)
