Suitability and adaptation of PROSAIL radiative transfer model for hyperspectral grassland studies
Atzberger C., Darvishzadehl R., Schlerf M., Le Maire G.. 2013. Remote Sensing Letters, 4 (1) : p. 56-65.
Methods are presented testing the suitability of PROSAIL radiative transfer model for analysing HyMap imaging spectroscopy data over grassland. The presented methods include forward modelling and cross-checks of 2D correlation plots. In the forward modelling, it is taken into account that the in situ data are not error free. To increase the predictive power of PROSAIL, a simple and fully automatic feature selection (FS) algorithm is presented identifying and discarding poorly modelled wavebands, yielding more reliable parameter retrievals.
