Automated terrestrial laser scanning with near-real-time change detection – monitoring of the Séchilienne landslide
We present an automated terrestrial laser scanning (ATLS) system with automatic near-real-time change detection processing. The ATLS system was tested on the Séchilienne landslide in France for a 6-week period with data collected at 30 min intervals. The purpose of developing the system was to f...

| description | We present an automated terrestrial laser scanning (ATLS) system
with automatic near-real-time change detection processing. The ATLS system
was tested on the Séchilienne landslide in France for a 6-week period
with data collected at 30 min intervals. The purpose of developing the
system was to fill the gap of high-temporal-resolution TLS monitoring studies
of earth surface processes and to offer a cost-effective, light, portable
alternative to ground-based interferometric synthetic aperture radar
(GB-InSAR) deformation monitoring. During the study, we detected
the flux of talus, displacement of the landslide and pre-failure deformation
of discrete rockfall events. Additionally, we found the ATLS system to be an
effective tool in monitoring landslide and rockfall processes despite missing
points due to poor atmospheric conditions or rainfall. Furthermore, such a
system has the potential to help us better understand a wide variety of slope
processes at high levels of temporal detail. |
