AN ESTIMATING METHOD OF SLOPE SAFETY BY AERIAL PHOTOGRAPHS

This paper describes a method estimating slope safety along railways by interpretation of aerial photographs. The method of rough investigation techniques reveals potential dangerous spots on slopes and streams along the JNR by a marking system. The method consists essentially of scoring each factor by a quantification theory, using maps depicting the topography, geology and vegetation. In the future these aerial photo techniques will be combined with infrared and false color photography.
