The results were validated with independent samples of LiDAR-derived height showing high accuracy (with the average R = 0.70 and RMSE = 10 m between all the algorithms and different training samples). The results confirm that it is possible to estimate forest canopy height using PolSAR parameters...

In this paper, the sensitivity of airborne LiDAR and Landsat-8 Operational Land Imager (OLI) based dominant canopy height and AGB 30 m mapping is assessed with respect to the season of Landsat acquisition for a ~10,000 Km2 tropical forest area in the Democratic Republic of the Congo. A ...

forest (Gentry, 1995). From wet evergreen to dry deciduous forests, prolonged drought correlates with a reduction in physiognomy andfloristiccomposition and the lowering of canopy height. At the same time, the degree of deciduousness of the trees of theoverstoryincreases. Thephenologyof these ...
Scientists have long been interested in studying the canopy, but the height of trees made research difficult until recently. Today the canopy is commonly accessed using climbing gear, rope bridges, ladders, and towers. Researchers are even using model airplanes and quadcopters outfitted with special...
