%description
Implements algorithms for terrestrial, mobile, and airborne lidar
processing, tree detection, segmentation, and attribute estimation
(Donager et al., 2021) <doi:10.3390/rs13122297>, and a hierarchical patch
delineation algorithm 'PatchMorph' (Girvetz & Greco, 2007)
<doi:10.1007/s10980-007-9104-8>. Tree detection uses rasterized point
cloud metrics (relative neighborhood density and verticality) combined
with RANSAC cylinder fitting to locate tree boles and estimate diameter at
breast height. Tree segmentation applies graph-theory approaches inspired
by Tao et al. (2015) <doi:10.1016/j.isprsjprs.2015.08.007> with cylinder
fitting methods from de Conto et al. (2017)
<doi:10.1016/j.compag.2017.07.019>. PatchMorph delineates habitat patches
across spatial scales using organism-specific thresholds. Built on 'lidR'
(Roussel et al., 2020) <doi:10.1016/j.rse.2020.112061>.
