Description Usage Arguments Value Examples
This function calculate the lad profile from the input lad.voxels
1 | lad.profile(VOXELS_LAD, relative = FALSE)
|
VOXELS_LAD |
3D grid of LAD values (output of lad.voxels() function) |
relative |
produce lad profile by relative total LAI values. Indicate when usinh effective LAI |
A data.frame
with the calculated Leaf Area Density

normlas.file = system.file("extdata", "lidar_example.laz", package="leafR")
# Calculate LAD from voxelization
VOXELS_LAD = lad.voxels(normlas.file,

ylab = "Canopy height (m)", xlab = "LAD (m2/m3)")
# relative LAD PROFILE
relative.lad_profile = lad.profile(VOXELS_LAD, relative = TRUE)
plot(relative.lad_profile$height ~ relative.lad_profile$lad, type = "l", ylim = c(0, 40),
