%description
Provides tools for preprocessing, feature extraction, and segmentation of
three-dimensional forest point clouds derived from terrestrial laser
scanning. Functions support creating height-above-ground (HAG) metrics,
tiling, and sampling point clouds, generating training datasets, applying
trained models to new point clouds, and producing per-point fuel classes
such as stems, branches, foliage, and surface fuels. These tools support
workflows for forest structure analysis, wildfire behavior modeling, and
fuel complexity assessment. Deep learning segmentation relies on the
PointNeXt architecture described by Qian et al. (2022)
<doi:10.48550/arXiv.2206.04670>, while ground classification utilizes the
Cloth Simulation Filter algorithm by Zhang et al. (2016)
<doi:10.3390/rs8060501>.
