Magnus Bremer and his colleagues published their work on 3D tree modelling from topographic LiDAR point clouds in Remote Sensing of Environment, which is one of the most important journals in its field.
Fine-scale architectural tree models serve as an effective representation of three-dimensional plant material distributions. They can help to quantify wood volume and biomass, to estimate leaf area distributions on a detailed scale, and can be exploited for physically based modelling approaches. If architectural tree models can be derived for multiple acquisition dates, they permit the detailed investigation of phenological effects.
