Remote sensing
Remote sensing is an important tool for the gathering of Earth Information. It involves monitoring and assessing the status of, and changes in the natural and man-made environment.

In recent years, Remote sensing has become more and more sophisticated with the development of air- and space-borne systems, including 3-D visualization and modelling.
It is therefore an important tool for geomorphological terrain mapping, together with the analysis in time and space of natural and man-induced hazards such as landslides, floods, earthquakes, desertification, soil degradation and volcanic eruptions.
