Before implementing measures to prevent rockfall disasters, it is necessary to clarify the distribution of rock-outcrops, the likelihood of a rockfall, its path, and probability of the rockfall reaching the track. Given the number of natural slopes adjacent to railway lines that would have to be surveyed however, it is difficult to obtain this information for all rock-outcrops. A rockfall hazard mapping method was therefore developed using Digital Elevation Models, which will enable engineers to identify rockfall risk along a railway line.
