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

Description

Creates a data frame of the 3D voxels information (xyz) with Leaf Area Density values from las file

Usage

lad.voxels(normlas.file, grain.size = 1, k = 1)

Arguments

normlas.file	normalized las file
grain.size	horizontal resolution (suggested 1 meter for lad profiles and 10 meters for LAI maps)
k	coefficient to transform effective LAI to real LAI (k = 1; for effective LAI)

Value

A data.frame of the 3D voxels information (xyz) with Leaf Area Density values

Note

The values of LAD are not estimated below 1 meter. For the following reasons: ground points influence realtive low sampling

Examples

# Get the example laz file
normlas.file = system.file("extdata", "lidar_example.laz", package="leafR")

VOXELS_LAD = lad.voxels(normlas.file,
                        grain.size = 2, k=1)
