Coherence X Instaling: Unlocking Ground Deformation Monitoring and Geohazard Evaluation

Interferometric Synthetic Aperture Radar (InSAR) has revolutionized the field of remote sensing, enabling researchers to measure ground surface motion with unprecedented accuracy. This technique is particularly valuable for monitoring ground displacements related to earthquakes, volcanic eruptions, landslides, karstification, mining, and groundwater abstraction.

The EZ-InSAR toolbox is an innovative solution that simplifies InSAR processing by automating the downloading of Sentinel-1 SAR imagery and digital elevation model data. This user-friendly interface also streamlines the preparation of input data stacks for time-series analysis, reducing the workload significantly.

EZ-InSAR integrates three popular open-source tools - ISCE, StaMPS, and MintPy - to generate interferograms and displacement time series using state-of-the-art algorithms within a seamless Graphical User Interface. This open-source toolbox enables researchers to implement InSAR displacement time-series analysis with multi-temporal SAR images in an effortless manner.

Thanks to the Copernicus Sentinel-1 SAR satellites, several open-source software packages are available for processing SAR data. However, these packages often require a deep understanding of InSAR theory and related computational tools, especially when dealing with large image stacks. EZ-InSAR fills this gap by providing a user-friendly interface that makes InSAR processing accessible to researchers without extensive expertise.

The toolbox has been tested on several volcanoes, including Campi Flegrei, where recent ground deformation was mapped using the Persistent Scatterer InSAR and Small-Baseline Subset approaches. The results were validated by comparing the InSAR displacements with Global Navigation Satellite System measurements.

In conclusion, EZ-InSAR is a valuable contribution to the community for ground deformation monitoring and geohazard evaluation, as well as for disseminating bespoke InSAR observations. By automating tedious tasks and providing a user-friendly interface, EZ-InSAR has the potential to revolutionize the field of InSAR processing, making it more accessible to researchers worldwide.
