Estimation and Comparison of Tree Attributes in Young Forest Using Different Remote Sensing: Drone LiDAR, Aerial Photogrammetry, and Open Forest Data

Autor: Gyawali, A., Peuhkurinen, J., Villikka, M., Aalto, M., Ranta, T.

The biomass stored in young forests has enormous potential of energy to reduce fossils fuel consumption in Finland. Nowadays, accurate measurement and providing 3D information of the tree at a low cost is necessary to manage the growth and yield of t
