tree_inventory_chablais3

All trees with diameter at breast height &gt;= 7.5 cm are inventoried on a 50m x 50m plot.

datasets

Provides functions for forest objects detection, structure metrics
computation, model calibration and mapping with airborne laser scanning:
co-registration of field plots (Monnet and Mermin (2014)
<doi:10.3390/f5092307>); tree detection (method 1 in Eysn et al. (2015)
<doi:10.3390/f6051721>) and segmentation; forest parameters estimation with
the area-based approach: model calibration with ground reference, and maps
export (Aussenac et al. (2023) <doi:10.12688/openreseurope.15373.2>);
extraction of both physical (gaps, edges, trees) and statistical
features useful for e.g. habitat suitability modeling (Glad et al. (2020)
<doi:10.1002/rse2.117>) and forest maturity mapping (Fuhr et al. (2022)
<doi:10.1002/rse2.274>).
