Inversion of the Li-Strahler GOMS model for component signatures and fractions

In this paper, a new method to combine hyperspectral and multiangular data together to retrieve subpixel information is introduced. This method begins from the definition of the component signatures and tries to get a priori information from the data itself, so it's more likely to acquire the "pure" endmember spectra and the subpixel information extracted by this method is more reliable than some other ways. To demonstrate the result of the method, we use BOREAS (the BOReal Ecosystem-Atmosphere Study) data to extract component signatures and the corresponding areal proportions in SSA (Southern Study Area) OJP (Old Jack Pine) site. The result is encouraging.
