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 | |
