摘要：The recent introduction of laser scanning devices has led to a set of new surveying products for the field of civil engineering and environmental analysis. The laser scanner is an instrument that permits one to acquire irregular point clouds of land areas, rivers and infrastructures in a fast and cheap way. The use of raw laser scanner data requires orientation and filtering procedures to generate a 3D model of the surveyed object., It is possible to automatically derive a set of geometric information from this 3D model that is useful for a variety of particular applications (engineering and environmental): dense DTM generation, sections and profiles, contour maps, volumes and so on. This paper describes an original, fully automatic software that has been implemented by the authors and which can supply a set of procedures that makes use of laser scanner data for engineering and environmental applications. Some pratical examples have been shown: the Lys stream in Pont Saint Martin in the Aosta Valley, a stone quarry in Bagnolo Piemonte and a landslide in St. Rhémy en Bosses in the Aosta Valley (Italy).
