Canopy Height Models of Iberian Peninsula 2018-2021 at 10 m resolution

Forest canopy height model for study areas distribuited along Spain (GALICIA/ EXTREMADURA/ANDALUCIA/LEON Regions, Rodeno, Guara (ARAGON), Cabañeros (CASTILLA Y LA MANCHA)), Portugal (7 study areas) using airborne Lidar data (ALS) collected in 2018, 2019, 2020 and 2021. The maps were produced by at the resolution of 10 m.

It starts by the creation of 500m x 500m tiles using a 50m buffer, resorting to the lastile function, followed by the lasheight function that is used to compute the elevation of each point above the ground. Then, the lastile function is used again to remove the buffer from the normalised point clouds. These first three steps resort to the LASTools software. The fourth, and final step, consists in the generation of the CHM with a 10 m resolution resorting to the pit-free algorithm implemented in the rasterize_canopy function from the lidR package.
