(English Abstract)
Geographic features are reflected in satellite im ages, which contain characteristic elements. Information on changes can be obtained through a comparison of images taken at different times. If multi-temporal im ages can be classified through the use of an unsupervised method, this is likely to improve the accuracy of image classification and contribute to various applications . A rule-based image classification algorithm for automatic processing without human involvement has been developed, but it must be verified that its results are not affected by im perfect elements. In this study, Landsat im ages of Jeju Island were used to carry out a rulebased image classification. The application results were examined for complex cases, including the presence of clouds in the images, different photographed times, and the type of target area, such as city, mountain, or field. The presence of clouds did not affect calculations, and appropriate classification rules were applied, depending on the different photographed times. The expansion of the urban areas of Jeju and the increase of facilities such as vinyl greenhouses in Seoguipo were identified. Furthermore, space information changes and accurate classifications for Jeju Island were obtained. W ith the goal of performing high-quality unsupervised classifications, measures to generalize and improve the methods employed were searched for. The findings of this study could be used in time-series analyses of im ages for various applications, including urban development and environmental change monitoring.
