This paper deals with the way of adjustment radiation quantity to develop a unified evaluation method of multi-temporal data as part of an environmental evaluation method using the satellite image. The proposed method is intended to automate reading of training data used for radiation quantity adjustment by extracting common class area during image, following the principle of post-classification comparison, based on land cover classification map produced under the supervised maximum likelihood classification method. Also, it adopted the way of adjusting the frequency distribution of the brightness information and that adjustment is made with threshold value. The effectiveness was shown as follows; it used LANDSAT/TM image. The difference occurring among multi-temporal data decreased, and it proved that the reference image and the comparison became possible relatively.
