Drones are aerial systems capable of autonomous or semi-autonomous (human-piloted) flight. They have recently become increasingly popular and accessible, providing many institutions and individuals with tools that can be used for a wide range of civil applications.

Various sensors, such as cameras, can be embedded to perform a specific task. The information or measurements obtained by sensors are useful in many fields, including geology, agriculture, industry, cinematography and even entertainment. Some applications can save lives, provide rescue services and help people in emergency situations.
