Abstract

Earth’s surface is constantly changing due to either natural processes or human activities. The systematic monitoring of surface deformation is an essential task to mitigate infrastructure risk and to ensure human safety. It is widely known that Persistent Scatterer Interferometry (PSI) constitutes an effective remote sensing technique for the measurement and monitoring of the Earth’s surface over time. The aim of the current work is to underline the capabilities of PSI technique for the monitoring of high-priority infrastructure in the framework of “PROION” project. The project is co-financed by the European Union and the Hellenic government, and its main objective is the systematic monitoring of national infrastructure in Western Greece using remote sensing data, in situ measurements and advanced soft computing methods. In light of SAR interferometry, an innovative type of corner reflector was designed and manufactured. These newly developed corner reflectors are described in detail along with their installation in the specified observation sites. Since PSI technique requires the generation of large time-series datasets, along with the need of a better understanding of the possible infrastructure motion, we obtained archived PSI measurements derived from the European Ground Motion Service. The specific data are offered free of charge through the Copernicus Land Monitoring Service. At this point, archived PSI measurements over the observation sites of PROION project, covering a time span of five years, were analyzed and interpret in order to understand the ongoing deformation processes.
