 Currently in Japan, the introduction of an International Linear Collider is being studied. In the initial stage of the construction, it is necessary to study not only the accelerator unit but also detailed locations of related ground facilities, in the light of constraints such as the topology. In particular, to efficiently extract the optimal area, and to promptly proceed to the design stage, it is essential to have a basement map that allows the user to finely and visually grasp the topology. Therefore, in this case example, the effectiveness of RRIM, which is one of the topology visualization techniques, and the method of utilizing it are studied. RRIM provides simulated color images that are synthesized by converting a digital elevation model that is acquired through airborne laser measurement etc. and enables the user to visually grasp fine topological images based on a representation method that is different from conventional hill shading or birds-eye view forming. It is widely used mainly as a basement map for slope disaster prevention management and forest management. This report is a product of joint research by Iwate University and ASIA AIR SURVEY.
