Terrestrial Laser Scanner has been used to detect rock falls which have occurred in a limestone cliff during some years, in the difficult configuration of the Subalpine Chains. In a rock wall of width 750m and height 200 m, 130 rock falls larger than 0.1 ...

<p>An active landslide in Doren, Austria, has been studied by multitemporal airborne and terrestrial laser scanning from 2003 to 2012. To evaluate the changes, we have determined the 3D motion using the range flow algorithm, an established method in computer ...

In tunnel construction, overcut along with undercut estimation is one of the most important factors to be considered before proceeding to the next operation. It is currently analyzed based on sparsely sampled points surveyed using a total station, but not ...

This case study deals with a rock face monitoring in urban areas using a Terrestrial Laser Scanner. The pilot study area is an almost vertical, fifty meter high cliff, on top of which the village of Castellfollit de la Roca is located. Rockfall activity is ...

<p>An innovative approach for the rockfall susceptibility analysis based on the combined application of Terrestrial Laser Scanner and Terrestrial SAR Interferometry has been developed. By this approach large and inaccessible rock scarps can be analyzed and ...

The paper describes some experiences carried out in monitoring of two rock faces in Italian Prealps in order to detect changes due to rock detachments. Since the forecasting of possible rockfall events is the main aim of this research, terrestrial laser scanning ...

Terrestrial laser scanning (TLS) is one of the most promising surveying techniques for rockslope characterization and monitoring. Landslide and rockfall movements can be detected by means of comparison of sequential scans. One of the most pressing challenges ...

In the present paper are discussed the technologies and are illustrated some experiments conducted in the framework of a project whose final goal is the installation of an integrated monitoring and alerting system on a rockface nearby Lecco (Italy).

A medium-ranged high performance handheld reflectorless laser measurement system, was used for a morphological survey on the Strug rock fall in W Slovenia in the period from August 2003 to August 2004. The purpose was to evaluate its potential for monitoring ...

<p>Terrestrial laser scanner has been used to detect rock falls greater than 0.01 m³ which have occurred during some years on a thin-bedded limestone cliff of the Subalpine Ranges, French Alps. Spatial- temporal rock fall frequencies have been determined ...
