Paper Abstract

The Li-Strahler geometric-optical model has been used with some success to simulate the bidirectional and hemispherical reflectance of forest canopies. Although the canopies modeled thus far may have contained trees of widely varying heights, the underlaying terrain has always been represented as level ground. Recently, however, the model has been extended to accommodate sloping terrain in its computation of the forest bidirectional reflectance distribution function (BRDF) and spectral surface albedo. With the model accommodating topography, it has been possible to compute and compare the reflective character of realistic forest canopies on a variety of slopes and aspects.
