The two main categories of light detection and ranging (LIDAR) for mapping and monitoring landslides are static and mobile devices. Static devices are commonly named ground-based LIDAR or terrestrial laser scanners (TLSs). Regarding mobile devices, the different instruments are normally classified depending on the platform configuration: either boats, cars or flying devices. There are three main types of LIDAR, corresponding to three different ways of measuring the range, for instance, the distance along the line of sight (LOS) between the sensor and the terrain. The types include: pulse LIDAR measures the time of flight (TOF) of a laser pulse; phase LIDAR uses the phase shift between the emitted and received signals; and triangulation LIDAR uses a camera to locate the laser spot on the scanned surface. Georeferencing is the process of coordinate transformation from an internal referential system relative to the LIDAR device into a real-world system of reference.
