Massive-scale tree modelling from tls data
WebFor the eucalyptus plot the total biomass was overestimated by about 8.5 %, when compared to a destructive reference (N = 27), and the modelling time was about 160 min. The method provides accurate and fast tree modelling abilities for, e. g., biomass estimation and ground truth data for airborne measurements at a massive ground scale.

Web15 de mar. de 2024 · Large multi-hectare areas of forests with thousands of trees can now be measured quickly with terrestrial laser scanning (TLS) ( Calders et al., 2015a). This kind of massive-scale remote sensing of trees requires that most, if not all, post-processing steps are done automatically. Web20 de abr. de 2024 · Background and aims: Terrestrial LiDAR scanning (TLS) data are of great interest in forest ecology and management because they provide detailed 3-D information on tree structure. Automated pipelines are increasingly used to process TLS data and extract various tree- and plot-level metrics. With these developments comes …
