Drones offer unique capabilities that can enhance situational awareness, search and rescue operations, damage assessment, and more in the face of natural and man-made disasters. In comparison to traditional manned relief operations; drones ensure safer, faster, and more effective management of disaster relief operations. Drones can help identify the disaster-prone area before the occurrence of disaster. During a disaster, the drones can provide high-resolution real-time images and videos of the entire location that will aid the rescue team to assess the situation, make relief plans promptly and real-time rescue operations. In post-disaster scenarios, drone-based mapping is carried out over the disaster-affected zones to assess damages and estimate the losses.
