摘要：In the last 5 years terrestrial laser scanning (TLS) technology has shown very large improvements, either in the instrumental aspects and in softwares for data processing and visualization. While first applications concerned only the architectural or in general the close-range field due to the small operating range, nowadays dealing with large scenarios is possible as well. New "long-range" TLS are really suitable to be applied in geological and glaciological surveying and monitoring, representing a very interesting issue for the Italian (and not only) research and social community, due to the mountain character of a large portion of its land. In the paper some guidelines for executing a survey of a landslide by means of TLS techniques are addressed; problems such as 3D- view registration, survey planning, data processing and information extraction are concerned. Furthermore, two application in this field carried out by a research group made up of Politecnico di Milano and the University of Brescia are presented. Geological application concerns the survey of a slope threatening a part of the village of Caslino d'Erba, near the Lake of Como, and the well- know marble quarry of Botticino (Brescia).
