Abstract: A management device that manages a flight route of a plurality of unmanned aerial vehicles (UAVs) includes a communication unit that acquires a detection result of an obstacle by a first UAV including an obstacle detection function and an evaluating unit that generates evaluation data of the flight route for selecting a UAV to fly on the flight route based on the detection result.

Abstract: A control device, non-transitory computer readable medium, and method for controlling an unmanned aerial vehicle (UAV), which acquires an allowable noise level identified on the basis of at least one of a time when the UAV is flying, an altitude at which the UAV is flying, an area where the UAV is flying, and weather in an airspace in which the UAV is flying; and controls flight of the UAV on the basis of the allowable noise level.

Abstract: A control device 200 includes at least one memory configured to store a program code, and at least one processor configured to access the program code and operate as instructed by the program code. The program code includes an acquisition code configured to cause the at least one processor to acquire a request for requesting determination as to whether or not a target area is usable for a predetermined purpose, and a control code configured to cause the at least one processor to perform control to cause a first flying object to fly to the target area. The acquisition code is configured to cause the at least one processor to further acquire sensing data that is data obtained by optical sensing of the target area by the first flying object. The program code further comprises a determination code configured to cause the at least one processor to determine, based on the acquired sensing data, whether or not the target area is usable for the predetermined purpose.
