Abstract : In the present study we describe a method to estimate the optical thickness of the atmospheric haze from a Landsat data set itself. Then we give a conversion method from the original CCT level data to the true ground albedo data with an aid of the Atmospheric Effect Correction System developed at the Kanazawa Institute of Technology. We also show that the signature extension become possible by correcting the original Landsat data for the atmospheric effects and this approach will be a powerful tool in temporal data analysis. Finally, a processing system implementing the signature extension of the remotely sensed data is described. As for such a signature extension system, we introduce a new and powerful table look-up method in classification and a data base containing the statistical information on albedos for various ground classes with time.
