Coastal environments are highly dynamic and fragile systems, constantly shaped by natural processes and human activities, and therefore require continuous and reliable monitoring. Geomatics techniques play a fundamental role in supporting this need, providing advanced tools for observing and analyzing coastal changes over time. This seminar will present the main findings of research conducted at Geomatics Lab of University of L’Aquila, providing, at first, the theoretical foundations of satellite imaging, highlighting the principles of SAR, its advantages compared to optical sensors, and key processing concepts relevant for environmental monitoring. The second part will present practical applications, specifically, the use of SAR data for coastal detection, with emphasis on shoreline extraction techniques. Both traditional and experimental algorithms will be discussed, offering insights into their performance and limitations. Additionally, the seminar will introduce PSInSAR (Persistent Scatterer Interferometry) methods applied to the analysis of ground deformation, focusing on infrastructure located in coastal areas. The session aims to bridge theory and application, providing participants with a clear understanding of how advanced remote sensing techniques can support coastal management and infrastructure monitoring.
The seminar will take place on April 30 from 09:30am-01:00 pm, in Room 173 S.Marta.
