 This research paper examines the use of lidar and hyperspectral imagery to map the spatial distribution of plant species in savannas. The authors found that combining the two datasets allowed them to accurately identify the species of trees in the area. They also addressed the challenge of flight line artifacts caused by anisotropic scattering properties of savanna vegetation, which could affect the accuracy of the results. By addressing these issues, they were able to create accurate maps of the species present in the savannas. This article was offered by Gregory P. Asner, Jean-Baptiste Ferret, Matthew S.
