Drones are becoming an essential tool in public safety for emergency response and search and rescue operations. They can be used to survey large areas quickly and safely, identify potential hazards, and locate missing persons. Additionally, drones can be used to create interactive 3D models of accident and crime scenes, providing detailed analysis and allowing for reconstruction of events. Their use in traffic pattern monitoring and crowd control can greatly improve response times and increase the safety of both first responders and the public.
