Abstract

During the last 20 years, the fast development of different remote sensors (Optical imaging, LiDAR, RADAR, etc) mounted over satellite, aerial or terrestrial platforms is changing our perception and interpretation of Earth's surface processes. Relative new sensors as LiDAR are allowing us to acquire each day faster, denser and more precise information about land terrain surface: we are now capable to acquire the 3D geometry of mountains, valleys and cliffs at different scales and with unprecedented level of detail. Consequently, LiDAR applications on landslide mapping, characterization, monitoring and modeling are shedding light into how landslides behave and evolve along the space and time. Some examples include, between others, the precise landslide mapping through the identification of geomorphological features, the accurate extraction of discontinuities orientation that play a key role in slope instability, the monitoring of landslides in order to analyze 3D displacements, or the magnitude/frequency quantification of fallen volumes along time in order to study erosion rates or to improve rockfall hazard assessment.
