Accompanied by the development and improvement for the theories and applications of the quantitative remote sensing, there are still many unprecedented challenges. Because of the Earth complexity of the surface and the limitation of the remote sensing information, the quantitative applications of remote sensing generally are hampered by ill-posed inversion, scale effect, and other problems. Especially for cloudy and hilly regions, sufficiently influenced by the cloud, topography, and
