Analytical Evaluation of Slope Failure Location Using ASTER Image Data
Harushige KUSUMI, Hiroshi WATANABE and Yu MORIMOTO
Abstract:In this research, the applicability of the satellite multispectral data to the predictions of slope failures has been attempted by using the data characterized by its broadness, synchronism, and periodicity, and by analyzing the causalities of various elements considered to be involved in the slope failures through the use of the qualification theory ‡U. Moreover, the risk assessment chart for slope failure will be made based on the result of it, which ultimately will make it possible to specify the slopes with failure risks on the basis of the development of risk assessment system for slope failure. Key Words:ASTER, Satellite multispectral data, Failure of slope danger evaluation, Qualification theory ‡U, NDVI.
