pcl_coded

Derived from data collected at the University of Virginia
Data collected August, 2016 by J. Atkins. Dervied from the calc_vai function

datasets

Provides a toolkit for calculating forest and canopy structural complexity metrics from
terrestrial LiDAR (light detection and ranging). References: Atkins et al. 2018 <doi:10.1111/2041-210X.13061>; Hardiman et al. 2013 <doi:10.3390/f4030537>;
