Abstract:
The Basilica of Vicoforte has always interested geotechnical engineers due to its location in a geologically complex area. One part of the Basilica is built on marl, while the other is built on clay. These two types of soil have different mechanical properties, which have caused the Basilica to experience various foundation failures over time. Monitoring is necessary to evaluate structural evolution and prevent further damage. Radar images are one of the geomatics techniques that can be used to perform these types of analyses; however, SAR data processing is challenging and requires specialized skills and software to monitor deformations using the PSInSAR approach. The European Ground Motion Service (EGMS) is useful for users and researchers, but analyzing specific buildings or monuments requires a more refined grid. The paper proposes a package of codes implemented using MATLAB release 2023b to manage grid spacing flexibly, customize it according to structure dimensions, and manage
potential blunders. After a thorough data analysis, it was concluded that the monument exhibits no signs of subsidence trends. Instead, the analysis revealed that it undergoes seasonal fluctuations closely associated with temperature changes. The proposed approach enhances data accuracy and reliability, resulting in valuable insights and informed decisions.
