Calculates the Leaf Area Index (LAD) and Other Related Functions

A set of functions for analyzing the structure of forests based on the leaf area density (LAD) and leaf area index (LAI) measures calculated from Airborne Laser Scanning (ALS), i.e., scanning lidar (Light Detection and Ranging) data. The methodology is discussed and described in Almeida et al. (2019) <doi:10.3390/rs11010092> and Stark et al. (2012) <doi:10.1111/j.1461-0248.2012.01864.x>.

leafR

Provides a set of functions for analyzing the ecological structure of forests based on LAI and LAD measures derived from LiDAR data.

Functions in leafR

Name Description
lad.voxels Creates a data frame of the 3D voxels information (xyz) with Leaf Area Density values from las file
lai.raster Produce a raster map of LAI. The resolution of the raster depends of grain.size choosed on lad.voxel() funtion.
LAHV Leaf Area Height Volume metric
lad.profile This function calculate the lad profile from the input lad.voxels
lai calculates the lead area index (LAI)
k.coefficient Calculate k coefficient provided a known real LAI and the calculated LAI
lidar_example.laz lidar_example.laz included raw data
