Estimation of the sea bottom spectral reflectance in shallow water with hyperspectral data

The inversion of the semi-analytical radiative tranfer model proposed by Lee allows to estimate the water column paramters and depth. The solution generally used to deal with the sea bottom reflectance at the inversion stage is to use a spectral library containing relevant reflectance spectra of the studied area. In this paper, we will evaluate the influence of that spectral library. For this purpose, the simplest possible spectral library will be used: a spectral library including only one flat spectrum. The observations made using that spectral library will show results that re-evaluate the purpose of the spectral library itself at the inversion stage, leading us to propose a method to estimate the sea bottom spectral reflectance.
