摘要：Terrestrial laser scanning (TLS) technology has recently increased its interest in the geological community for the geometric survey of slopes involved in landslides and for the acquisition of a DSM of rock wall, that can be used for predicting possible paths of falling dawn stones. In particular, the paper deals with this last application, focusing on some open aspects which have devised to be accurately studied. Firstly, a method for the survey planning is proposed, which is particularly devoted to the application to rock wall survey. Secondly, operational issues such as the selection of ground constraint, the materialization and the measurement of ground control points (GCP) are proposed, as well as a solution for the positioning of GCPs. Finally, some concerns about data collection and processing are afforded
