Ground displacements in the form of settlements, landslides and sudden collapses are frequent phenomena that occur as a response to natural features of the soil and the quality of the foundation, with the potential to cause significant damage to buildings and infrastructures. This is why the early detection and monitoring of such deformation patterns help to prevent and mitigate risk in densely inhabited areas, providing a valuable information to effectively take decisions. In advanced geomatics, Differential Synthetic Aperture Radar Interferometry (DInSAR) techniques provide a non-invasive instrument to remotely detect, map and monitor deformation phenomena affecting urban areas. Consequently, DInSAR techniques are used to generate velocity maps and displacements time-series for a large number of measurement points and long observation periods.
Survey Lab is a Spin-Off University of Rome that develops and commercializes innovative services for the mapping and monitoring of uninhabited areas, buildings and infrastructures. Recently, Survey Lab has worked in the I.MODI project (2016-2018), focused in developing a system to monitor ground displacements and model deformation of civil structures using EO data. In line with its mission, through the MUSA project, Survey Lab is aimed to obtain quantitative indicators on the data quality used for the detection and monitoring of displacements, as well as to the analysis of spatio-temporal deformation trends. To accomplish this, the MUSA project focus in the development of advanced geostatistics tools to model the spatial distribution of the information (displacements and displacement rates) generated by applying DInSAR techniques on data provided with different spatial and temporal resolutions.
