Abstract

This paper was under taken in order to classify aerial photograph by using maximum likehood classification on GIS. Results are as follows: 1)Classification of aerial photograph that composited LANDSAT/ETM data band4 was found to have higher the average of classification accuracy than aerial photograph of no composite. The improvement rate was 5%. 2) If the high resolution aerial photograph was used, such as residential district and track that is easy to mix pixel in low-resolution satellite was possible to classify it in higher accuracy.3) Appearance of urbanization by forest development and invasion of bamboo influenced by ground level environment to forest was able to be caught in detail by the overlay analysis between the ages in the land cover classification map. Therefore, this technique becomes one of the new methods of analyzing a remote sensing.
