PiC: Interactive Processing and Segmentation of Forest TLS
Point-Cloud Data
Tools for the processing, segmentation, and analysis of terrestrial laser
scanning (TLS and MLS) forest point-cloud data. The package provides fast
voxel-based processing, classification of point clouds into forest
floor, understory, canopy, and woody components, and algorithms for
single-tree analysis and structural characterization. Methods are designed
to handle large and dense point-cloud datasets efficiently, supporting
applications in forest structure assessment, connectivity analysis, and
fire-risk evaluation. Input data are provided as '.xyz', '.txt', '.las', or '.laz' point-cloud files.
