Many of infrastructures were intensively developed during period of rapid economic growth, and the increasing demand for maintenance management due to aging is an urgent issue, and more efficient and strategic maintenance management is required. In road maintenance management, two-dimensional data are used. However, it is difficult to grasp the detailed structure of bridges and slopes and inspection points. There is a problem that inexperienced engineers may not have a correct understanding of the on-site situation. In this study, we proposed a information system that measures and visualizes road damage as three-dimensional point cloud data and visualizes it on a two-dimensional map, in order to improve the efficiency of maintenance work and to accumulate data. The system was evaluated by practitioners, and its usefulness and issues were indicated.
