| Sumario: | LiDAR (Light Detection and Ranging) is an extremely effective and consolidated technology based on laser light, whose purpose is the
geometric-spatial remote detection, through the calculation of the distances of the target object carried out through the so-called time of flight
TOF (Time of flight or time that the wave takes between the instant in which it is emitted and that in which it is received).
Since the 1980s it has been used in the characteristic sectors of geomatics, but not only: thanks to the combined data deriving from global
positioning systems (GPS) and inertial measurement units (IMU) it was possible to identify the accurate positioning of aircraft. in flight.
Therefore, although it is not a recent technology, in recent years it has been used in numerous geospatial projects.
Lidar data can be expensive, however, due to the growing demand - an offer characteristic of the geospatial user community - we are starting to see
the availability of open source LiDAR data sets, i.e. made available to the public.
