Lidar technology is widely applied in disaster management. It precisely presents 3D shapes and accurately locates features in a scene Lidar measurement can be used to monitor land subsidence and analyze potential trend of subsidence, so that preventive measures can be taken. With Lidar technology, we can create visual maps of the disaster area and extract important information about the area. It can accurately identify safe locations for shelters and risky areas in mudslides or flood. With mobile-based or UAV-based Lidar, governments can react promptly in face of massive disasters, which makes it become a very important technology in real-time disaster response and management.
