  • Marion Jourdan (AgroParisTech student) used the AMAPstudio software suite to produce highly detailed and realistic 3D mock-ups of maritime pine stands. These mock-ups are to be used for modelling the interaction of LiDAR signal and vegetation with DART (Cesbio Toulouse) and LiDART (AMAP). AmapSim was used to simulate stands of trees growing in interaction. Xplo and Simeo were used to extract individual or stand parameters from the mock-ups in order to compare them to those observed in real trees stands. The model parameters of individual trees (i.e. simulated without neighbours) were first adjusted using the following response variables: total height and height of the first living branch, projected crown surface, total leaf area and diameter at breast height. Then, stands of pines were simulated, introducing explicit competition for space between neighbouring trees and management thinning and the model parameters were adjusted using the gap fraction as response variable. This internship was funded by the CNES and is part of the STEM-LEAF project (check the project page). (C. Madelaine-Antin, 25.11.2014)

  • Clemens Weissteiner, Phd-Student at the University of Natural Resources and Life Sciences (Vienna) is using Xplo to import MTGs from several recorded riparian trees. Beside a proper visualization of the tree models, Xplo is used for extracting and analysing different geometrical-topological parameters of the trees to understand better the influence of hydrodynamic loading on riparian vegetation. Furthermore he would like to export 3D-Models to CAD-Software and later for modelling the deformation of the plants under hydrodynamic loads. (Clemens Weissteiner, 13.11.2012)
