Simulation of the BRDF of forest cover with the coupling of high and medium resolution reflectance models

Information extraction from remote sensing data with the help of physical modeling requires an approach that retains the 3D complexity of covers while dealing with a limited data volume, i.e. the scene is made of a small number of complex elements. Therefore, the authors developed a methodology that couples a high and a medium reflectance models: output (i.e. mean transmittance and scattering phase functions) quantities of the high resolution model are used as input parameters to the medium resolution model. Preliminary results are encouraging
