“…Due to their high-resolution capability, they have been extensively used to detect the deformation time-series of multiple natural targets on different types of linear infrastructure, especially bridges (Gagliardi et al, 2022;Caspani et al, 2023). The European Ground Motion Service (EGMS), as an essential section of the Copernicus Land Monitoring Service (CLMS) framework, provides a freely-accessible continent-wide database of information regarding ground deformation almost all over Europe (Crosetto et al, 2020;Costantini et al, 2022). The project, which has been carried out by Sentinel-1 InSAR processing, has brought the opportunity for different monitoring purposes, such as geo-hazard assessment and urban area and infrastructure monitoring.…”

Abstract. This paper elaborates on the potential of the deformation time-series provided by European Ground Motion Service (EGMS) data points for bridge monitoring, in terms of the response of bridge structures to temporal and thermal deformations. For this purpose, high-resolution Cosmo-SkyMed (CSK) Synthetic Aperture Radar (SAR) images have been utilized through Persistent Scatterer SAR Interferometry (PS-InSAR) to derive spatially detailed deformation time-series of two bridges located at the north of Lombardy region, Italy. Then, the Annual Displacement Velocity and Thermal Expansion Coefficient of the data points in both datasets are extracted based on the corresponding deformation time-series. The response parameters are post-processed through projection and compensation steps to become comparable. Cross-checking the results by comparing the response parameters along the bridges showed that the global (for L3 products) and local (for L2b products) differential behaviour and the variation of the values of these parameters from one side to the other side of each bridge are consistent between CSK and EGMS datasets. However, the EGMS L3 information shows a slightly lower magnitude in both displacement velocity and thermal expansion coefficient responses. According to the revealed capability of EGMS information in this work, it can be concluded that the EGMS data points, if spatially cover a bridge, can present a reasonable and sufficient insight into the temporal evolution of displacement and thermal structural response, suitable for structural health monitoring and condition assessment of bridges under operational and environmental loads.

“…In the last decades, many European Nations have enabled satellite-RADAR-based services for the monitoring of their territories, e.g., Italy [19]- [21], Norway [22], and Germany [23]. In 2017, a turning point has been the approval of the European Ground Motion Service (EGMS) [24] by the Copernicus Land Monitoring Service. The new EGMS gives deformative information obtained by the processing of the enormous archives of Synthetic Aperture Radar (SAR) images acquired by the Sentinel-1 constellation in the period 2015-2020, at the continental scale.…”

The Structural Health Monitoring of urban settlements can be pursued today exploiting satellite remote sensing Advanced Differential Synthetic Aperture Radar interferometry (A-DInSAR) techniques. At the European scale, the new European Ground Motion Service (EGMS) gives the deformative information obtained by the processing of the enormous archives of Sentinel-1 Synthetic Aperture Radar (SAR) images in the period 2015-2020. In this work, a new procedure for valuable use of EGMS-derived data aimed at the monitoring of the deformations of urban areas is presented. The procedure includes the exploitation of a tool, called ADAfinder, which is able to extract active deformation areas (ADA) from datasets of measuring points, which means, it creates maps of areas affected by deformations above an estimated threshold. The aim of the procedure is the identification of buildings included in ADA, representing the buildings that require special attention, in terms of on-site monitoring or inspections. An application is presented, regarding a portion of the Zona Franca industrial area, in the city of Barcelona (Spain).

Abstract. Monitoring ground deformation at national and regional level with millimetre-scale precision, nowadays, is possible by using Advanced Differential Interferometric SAR (A-DInSAR) techniques. This study concerns the results of the European Ground Motion Service (EGMS), part of the Copernicus Land Monitoring Service, which detects and measures land displacement at European scale. This Service provides reliable and consistent information regarding natural ground motion phenomena such as landslides and subsidence. The ground motion is derived from Synthetic Aperture Radar (SAR) time-series analysis of Sentinel-1A/B data. These data, which provide full coverage of Europe from two different observation geometries (ascending and descending) every six days, are processed at full resolution. The paper is focused on the exploitation of the basic product of EGMS for both regional and local purposes. Analysing the slope and aspect of the deformation field is the novelty of this investigation. In particular, the focus is put on the generation of wide-area differential deformation maps. Such maps indicate the gradient of the deformation field. The obtained information is not only beneficial for monitoring anthropogenic phenomena but also vital for urban management and planning. Most of the significant damages to manmade structures and infrastructures are associated with high deformation gradient values. Thus, monitoring the temporal and spatial variations of deformation gradient is essential for dynamic analysis, early-warning, and risk assessment in urban areas. Although EGMS productions are prepared for monitoring at regional level, their resolutions are high enough to investigate at local level. Therefore, this paper considers the local deformations that affect single structures or infrastructures. Local differences in such deformation can indicate damages in the corresponding structures and infrastructures. We illustrate these types of analysis to generate differential deformation maps using datasets available at CTTC.
