Application of 3D laser scanner for monitoring of landslide hazards

چکیده
Landslide hazards are one of the major natural hazards. It is difficult not only to get the integrated and accurate landslide datum but also to monitor and predict the landslide. This paper introduces a ground-based laser scanner application for the landslides monitoring and its experiment in Jingyang, Shaanxi province. The point cloud gained in the test region is processed by existing software, and the result of experiment shows that ground-based laser scanner is effective in monitoring of landslide hazards.

متن کاملThe Application of Terrestrial Laser Scanning for Monitoring Natural Hazards
Terrestrial laser scanning is used as a helpful observation method in hazard assessment to collect 3D data from changing landscape surfaces, to obtain information about the current states of natural hazard processes. Three different applications of terrestrial laser scanning for monitoring natural hazard are presented to better understand the method of application, based on the outcome of previ...
متن کاملApplication of a Terrestrial Laser Scanner (TLS) to the Study of the Séchilienne Landslide (Isère, France)
The active Séchilienne landslide (Isère, France) has been continuously monitored by tacheometry, radar and extensometry devices for 25 years. Indeed, if the 3 mil. m 3 of rocks in the active zone named ―Ruines‖ fell down, the debris would dam the Romanche valley. The breaking of the dam by overtopping and rapid erosion would bring a catastrophic flood and other dramatic consequences throughout ...

Landslide is one of these natural hazards which causes a great amount of financial and human damage annually allover the world. Accordingly, identification of areas with landslide threat for implementation of preventive measures in order to confront against the instability of hillsides for reduction of potential threats and related risks is very important. In this research a new method for clas...
متن کاملAutomated quantification of distributed landslide movement using circular tree trunks extracted from terrestrial laser scan data
This manuscript presents a novel algorithm to automatically detect landslide movement in a forested area using displacements of tree trunks distributed across the landslide surveyed repeatedly using terrestrial laser scanning (TLS). Common landslide monitoring techniques include: inclinometers, global position system (GPS), and interferometric synthetic aperture radar (InSAR). While these techn...
