The terrestrial laser scanner allows complete and dense 3D digital models of the surface of any object to be reconstructed. This is very useful for natural hazards and risk assessment where morphological investigation is a starting point to evaluate stability properties. In the case of disaster management, a 3D model is useful to acquire and monitor emergency situations. Field acquisitions, with laser scanner
