I am making an algorithm that inverts the prosail model to obtain the biophysical parameters from spectra obtained by a hyperspectral camera on board a drone.
To better adjust the results I would like to use the dry and wet sand spectra from the study area instead of using the spectrum from the database.
I have investigated and I see that there is the possibility of using external spectra through the UseExternalSoilDB method, which uses as an input parameter a SoilDataBase object which is constructed from a file.
I have not been able to find any file examples or the format that the data has to have in order for it to be imported correctly. Does anyone know how to import the spectra data and what format the file should have?
Thanks and regards …
