lai: calculates the lead area index (LAI)

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

Description

calculates the lead area index (LAI)

Usage

lai(lad_profile, min = 1, max = 100)

Arguments

lad_profile	output of the lad.profile function
min	mix canopy height
max	max canopy height

Value

A numeric containing the LAI calculated from the Leaf Area Density

Note

The use of min and max arguments allowed the estimation of the LAI for different vertical strata

Examples

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

# Calculate LAD from voxelization
VOXELS_LAD = lad.voxels(normlas.file,
                        grain.size = 2)

# Calculate the LAD profile
lad_profile = lad.profile(VOXELS_LAD)

lidar.lai = lai(lad_profile); lidar.lai
understory.lai = lai(lad_profile, min = 1, max = 5); understory.lai

# relative LAD PROFILE
relative.lad_profile = lad.profile(VOXELS_LAD, relative = TRUE)

#understory relative LAI (% of total LAI)
relative.understory.lai = lai(relative.lad_profile, min = 1, max = 5); relative.understory.lai
