This strategy consisted of a relative evaluation, changing the input factors (parameters and models) in the configuration to identify how they affect in the estimation of the surface reflectivity. ...
In the first group, image-based techniques, a number of methods have been developed to remove or reduce atmospheric effects and retrieve the surface spectral reflectance. ...
As principal researchers: Francisco Eugenio, Javier Marcello and Javier Martín contributed to algorithm implementation, data preparation and results generation. ...
