quatre_montagnes

Dataset of forest parameters measured in the field on 96 circular plots of 15 m radius. Metrics derived from airborne laser scanning (ALS) point clouds have also been extracted and calculated for those plots.

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>).
