aRchi-class

aRchi

Class containing files to compute and display in three dimensions tree architectural metrics at different level of organization

Provides a set of tools to make quantitative structural model of trees (i.e the so-called 'QSM') from LiDAR point cloud, to manipulate and visualize the QSMs as well as to compute metrics from them. It can be used in various context of forest ecology (i.e biomass estimation) and tree architecture (i.e architectural metrics), see Martin-Ducup et al. (2020) <doi:10.1111/1365-2435.13678>. The package is based on a new S4 class called 'aRchi'.
