The development and diffusion of unmanned and remote controlled flying platforms (drones) has induced the universities and scientists to use these systems in many scientific field where is fundamental the observation, the inspection and management of critical areas by the remote sensing.
A drone can be equipped with small and compact instrumentation, precision GPS systems, thermal and multispectral cameras, magnetometers and high resolution cameras capable of performing reporting maps in very high precision, thermal photographs, high definition video footage, but also gas or ground material sampling or tools release.
Thus allowing to explore extreme sites and collect a wide range of useful data and details in short time for the study of natural phenomena and environmental monitoring, with very low operating costs.
These high-performance multipurpose flight systems can now safely access inaccessible environments. At the same time, they have stimulated technological research to develop new airborne instruments and sensors and new remote observation techniques.
