Application of Tls to Support Landslides Study: Survey Planning, Operational Issues and Data Processing
نویسندگان
چکیده
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.

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...

متن کاملLandslide Monitoring Using Terrestrial Laser Scanner: Georeferencing and Canopy Filtering Issues in a Case Study
In order to define a methodology that faces the major critical issues, we used a Terrestrial Laser Scanner to monitor a large landslide that caused significant disruptions both to an important state road and to a major railway line in Italy. To survey the landslide we used three different models of Terrestrial Laser Scanners, including a "full wave form" one, potentially useful for filtering ve...
