Until now, it was not possible to share the video being shot in real time with the countermeasures headquarters at a remote location with the drone alone, and the video could only be seen after shooting, so there was a problem with the immediacy of information.

　Therefore, in this disaster prevention drill, "Real-time sharing of the on-site situation taken by the drone is a new method in the administrative organization that is required to appropriately implement evacuation calls and disaster prevention measures against the precursors of flood damage. A demonstration experiment was conducted to verify "whether it is effective".

　In the demonstration experiment, V-cube Robotics Japan Co., Ltd., which provides drone services to companies and local governments, to the countermeasures headquarters composed of the mayor of Joso City, staff, fire departments, police, and staff of the Geographical Survey Institute of the Ministry of Land, Infrastructure, Transport and Tourism. A monitor that displays the screen of the Web conferencing service is installed.Using a drone developed by Amuse One Self Co., Ltd., which manufactures and sells commercial drones, and has abundant use records at disaster sites, the operator who operates the drone receives instructions from the countermeasures headquarters through the Web conference service. The state of the river and the water level were photographed at the riverbed of the Kinugawa, and the images were transmitted to the countermeasures headquarters.In response to the situation at the site, the Countermeasures Headquarters held a countermeasures meeting similar to that at the time of the disaster, and verified whether it would lead to smooth drafting of countermeasures.
