5th Infrastructure Maintenance Award Minister of Internal Affairs and Communications Award Winner "Investigation of Obstructing Trees from the Air Using Drones"
Benefits of Drone-Based Obstruction Tree Surveys Until now, the prediction and removal of obstruction trees relied on the experience and intuition of skilled technicians. However, due to persistent issues with communication conditions, it has been difficult to select and remove trees appropriately. By conducting efficient surveys with drones and creating 3D models from the obtained photographic data, it is possible to identify obstruction trees on a one-by-one basis by overlaying this data with visualized microwave propagation paths. Furthermore, by simulating tree growth in 3D, it is possible to identify trees that will obstruct radio waves in the future on a one-by-one basis. As a result of drone-based obstruction tree surveys, identifying obstructive trees has eliminated the need for extensive logging, allowing for consideration of environmental impacts and achieving cost benefits of up to 50%.

"The Era of Utilizing Drones for Infrastructure Inspections and Maintenance" Many infrastructures, such as roads, bridges, and tunnels, which were built en masse during the period of rapid economic growth, are now over 50 years old, and inspections have not kept pace, leading to neglect. For example, the Ministry of Land, Infrastructure, Transport and Tourism mandated in 2014 that bridges and tunnels over 2 meters in height undergo regular inspections through close visual observation every five years; however, issues have arisen due to personnel and budget shortages. As a result, the introduction of drones for some inspections has begun to attract attention, and we are now in an era where drone operations are commonplace. Towa Drone Service supports the promotion of digital transformation (DX) at customer sites by converting inspection and survey data for public and power infrastructures into 3D formats.
