Designs of medium scale hazard maps of mountain slopes in Japan

Isao Akojima

The ultimate hill-slope hazard map may be a map showing the degree of hazard risk of each geomorphic units, but no such a quadangle sheet has been drawn yet. For the present, the exact distribution of the concave type hillslope, that is the slope of landslide or of talus, is still important for a practical use. And so, how to express the slope topography clearly is the first problem in making the medium scale geomorphic hazard sheet and then how to draw rapidly is the second. Some part of the two problems are solved by the computer mapping method using the finer degital elevation model.
