The International linear collider (ILC) is the world’s largest and most advanced electron-positron collider with a total length of 20 km, and its candidate site is Kitakami mountainous area in Tohoku. The construction of ILC involves the establishment of related ground surface facilities such as an onsite campus, an access road, and an access tunnel entrance, in addition to the collider itself. In this research, while mainly assuming the establishment of an access tunnel entrance facility, we created a red relief image map (RRIM) through UAV laser survey in the ILC candidate site and verified its effect on the detailed facility arrangement study. The UAV laser survey was conducted in prefectural forests of Iwate Prefecture in 2019. The RRIM created based on the survey data made it possible to grasp the ground surface, angle of the slope, collapsed lands, forest roads hidden by trees, traces of an old charcoal kiln. In addition, with the longitudinal and traverse figures and contour lines obtained from the survey data, we considered it possible to conduct the study of the facility location and the arrangement plan appropriately and efficiently.
