Control device, system, and method

A system comprising a terminal device and a control device, wherein

• the terminal device comprises a first communication circuit configured to transmit a request for requesting determination as to whether or not a target area is usable for a predetermined purpose,
• the control device comprises:
• a second communication circuit configured to receive the request;
• at least one memory storing 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 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 upon reception the request,
• the second communication circuit is configured to further receive sensing data that is data obtained by optical sensing of the target area by the first flying object, and
• the program code further includes a determination code configured to cause the at least one processor to determine, based on the received sensing data, whether or not the target area is usable for the predetermined purpose.

A method comprising:

• acquiring a request for requesting determination as to whether or not a target area is usable for a predetermined purpose;
• performing control to cause a first flying object to fly to the target area;
• acquiring sensing data that is data obtained by optical sensing of the target area by the first flying object;
• and
• determining, based on the acquired sensing data, whether or not the target area is usable for the predetermined purpose.
