Unlocking the Power of Coherence: Installing EZ-InSAR for Advanced InSAR Analysis

Interferometric Synthetic Aperture Radar (InSAR) has revolutionized the field of remote sensing, enabling us to monitor ground surface motion with unprecedented accuracy. One of the key challenges in implementing InSAR is the complexity of data processing and analysis. To overcome this hurdle, researchers have developed various open-source tools that streamline the process and provide high-quality results.

In this article, we will introduce EZ-InSAR, an innovative toolbox designed to facilitate user-friendly implementation of InSAR displacement time series analysis using multi-temporal SAR images. With EZ-InSAR, users can effortlessly download Sentinel-1 SAR imagery and digital elevation model data for their area of interest, preparing input data stacks for time-series InSAR analysis.

The Science Behind Coherence

InSAR works by exploiting the phase information of two radar images of a specific region collected at different times. The images are co-registered, and the phase information is differenced to produce an interferogram. This technique has been widely used to monitor ground displacements related to earthquakes, volcanic eruptions, landslides, karstification, mining, and groundwater abstraction.

EZ-InSAR: A Game-Changer for InSAR Analysis

EZ-InSAR integrates the three most popular open-source tools (ISCE, StaMPS, and MintPy) within a seamless Graphical User Interface. This means that users can generate interferograms and displacement time series using state-of-the-art algorithms without requiring extensive knowledge of InSAR theory or computational tools.

Case Study: Campi Flegrei

To illustrate the capabilities of EZ-InSAR, we mapped recent ground deformation at Campi Flegrei, which exhibited a significant displacement of over 100 mm. Our results demonstrate the potential of EZ-InSAR for monitoring ground surface motion in areas prone to natural hazards.

In conclusion, installing EZ-InSAR provides researchers and practitioners with a powerful tool for advanced InSAR analysis. By simplifying the processing workflow and providing high-quality results, EZ-InSAR is poised to become a valuable contribution to the community for ground deformation monitoring and geohazard evaluation. With its user-friendly interface and seamless integration of open-source tools, EZ-InSAR is an essential resource for anyone working with InSAR data.
