Evaluation of HYPERION data for forestry applications: coastal Douglas-fir and western hemlock

This study summarizes a comparison between the NASA EO1 HYPERION and AVIRIS sensors for discriminating forestry attributes. The results suggest that the two sensors have qualities that result in reflectance profiles that exhibit many similarities with respect to discrimination of a variety of forest foliar and structural characteristics. In some cases the HYPERION reflectance data appear to be better at discriminating specific criteria, in spite of the lower signal to noise characteristics.
