Abstract
In the case of urban planning, it is necessary to quickly collect objective and scientific material and a lot of urban environment information. It is possible to quickly collecting the material, if the computer is utilized in order to carry out quantitative analysis of structure and form of urban area and extraction of the change region which arose by the progress in the time, etc. In this study, the structure of the urban area is quantitatively evaluated by the fractal analysis of aerial images which photographed actual area from the air. Then, it is shown that the classification of the form is possible. The extraction technique of the change region in the urban area using fractal analysis of aerial images of identical area photographed in the different time is proposed. Consequently, it is clarified that the fractal analysis method is an effective method for quickly collecting basic date in urban planning.
