Continuous monitoring for the reopening of a road section affected by a landslide event
A landslide interrupted an important provincial road connecting villages and places of great tourist interest. For the reopening of this stretch, continuous monitoring is necessary to ensure control of the unstable slope.
In the framework of the monitoring campaign, in addition to the techniques of Terrestrial and Satellite SAR Interferometry and Laser Scanner surveys, long-term monitoring was performed by means of multi-temporal analysis of optical images acquired at 10-minute intervals (Photomonitoring).
The continuous monitoring, carried out through the use of different techniques in the field of Remote Sensing, has allowed the detection of the main unstable sectors and the control of the evolution of the slope over time, assuring the reopening of the road section.
