Unmanned aerial vehicles (UAVs), also known as drones, have been around since the early 1900s. Originally used for military operations, they became more widely used after about 2010 when electronic technology got smaller, cheaper and more efficient, prices on cameras and sensors dropped, and battery power improved. Where once scientists could only observe earth from above by using manned aircraft or satellites, today they are expanding, developing and refining their research thanks to drones. Drones have many advantages over traditional forms of research. With our drone survey equipment, researchers can create maps of previously inaccessible areas and explore places where traditional tools cannot go. Drones are used in a variety of ways by scientists for scientific research. Drones give researchers a better understanding of the places where they live and how to protect them.
