Search & Rescue
A search and rescue drone is an unmanned aircraft for searching over vast areas for missing persons or pets in need of rescue in any environment. Drones can provide real-time visual information and data in the aftermath of an earthquake or hurricane. They can also become an eye in the sky to locate a lost person in the mountain, for example. When a disaster or incident threatens lives or livelihoods, emergency responders need information and real-time imagery to make better decisions and save time. Drones can provide situational awareness over a large area quickly, reducing the time and the number of searchers required to locate and rescue an injured or lost person/pet, significantly reducing the cost and risks of search and rescue missions.
As above, one of the best solutions for Search&Rescue via drone is thermal imaging.
Some several groups and individuals use their drones for Search&Rescue. Drone SAR For Lost Dogs UK, for example, was set up to use drones to help find missing dogs. It has snowballed over the past 18 months, they now have over 900 volunteer pilots across the UK, and a social media group with over 21,000 members and they have assisted with over 1500 missing dogs! Not only have they help search for beloved pets, but they're ground team, and air teams have also helped in searches for missing people.
