Field trip to Corvara & drone flights
Landslide monitoring using UAVs flight and hands-on session
The field trip will lead us to the Corvara landslide. After an introduction to the environmental context of this complex phenomena (e.g. geomorphology, movement dynamics), past and current monitoring activities (i.e. in-situ measurements, UAV and remote sensing based monitoring) will be explained in the field. An introduction to multitemporal SAR interferometry will be also carried out prior to the trip.On-site discussions on the currently installed instrumentation (e.g. corner reflectors, GPS stations) and on associated research activities will give insights into the potentials and limitations of above-ground displacement monitoring of large and complex landslides. During the field trip, a flight with a drone will be carried out.The participant will learn how to plan and conduct an UAV flight campaign by using and applying some specific instrumentation and techniques. We will collect the necessary data to process and obtain high resolution digital elevation models (DEMs).
Finally, we will use the updated DEMs to compare with previous campaigns in order to create Digital Models of Differences (DoD) that quantifies the volumetric change between successive topographic surveys.The acquired images will be analyzed to understand the landslides movement in a practical session the day or two after the trip. This practical session focuses on monitoring mass movements, particularly on landslides, by evaluating proximal and ground sensing methods.
