`lidaRtRee` is an `R` package that provides functions for **forest analysis using airborne laser scanning** (LiDAR remote sensing) data: tree detection / segmentation and area-based approach. It includes complementary steps for forest mapping: extraction of both physical (gaps, edges, trees) and statistical features from LiDAR data, model calibration with ground reference, and maps export.
