In the present study we describe a method to estimate the optical thickness of the atmospheric haze. A true surface reflectance data set is obtained from a LANDSAT data set by using the Atmospheric Effect Correction System developed at Kanazawa Institute of Technology. A data base of classes of land covers containing the statistical information on the spectral reflectance is constructed from true surface reflectance data sets. Finally a new and powerful table look-up approach in classification is described and the results are presented.
