Description

This function reads in a hdf5 file and create a brightness matrix to remove shaded pixels for use in the BRDF correction that is applied in later steps.

Arguments

hy.file

hdf5 file containing hyperspectral imagery and associated metadata

metadata.path

hdf5 path to reflectance metadata

reflectance.path

hdf5 path to reflectance data
