Abstract

This work is based on the method suggested for correction of reflectance anisotropy in imaging spectroscopy data, outlined at (i), using corresponding elevation data and multi-angular spectral measurements from a goniometer. We focus on the development of tools that can make Bidirectional Reflectance Distribution Function (BRDF) correction ready for operational use by the community of imaging spectrometry users and developers. The new package of tools called collectively BREFCOR (Bi-directional reflectance correction) is at its beta phase. Here we present the underlying angle-dependant spectral measurements and some sample results from BREFCOR's
correction of the CASI and HYMAP imaging spectrometers.
