dolphin

The dolphin library is an open-source tool designed for advanced InSAR (Interferometric Synthetic Aperture Radar) data processing. Its core functionality revolves around phase linking, a sophisticated method used to derive precise measurements of ground deformation and surface displacement from SAR imagery. This capability is essential for monitoring changes in the Earth's surface caused by natural phenomena or anthropogenic activities.

The library integrates processing techniques for both Persistent Scatterer (PS) and Distributed Scatterer (DS) interferometry. PS InSAR focuses on stable, point-like targets that maintain high coherence over time, while DS InSAR leverages areas with distributed but statistically homogeneous scattering characteristics. By combining these approaches, dolphin aims to provide comprehensive and robust surface displacement maps, enhancing the accuracy and spatial coverage of deformation analyses.

Developed within the ISCE framework, dolphin is a valuable resource for researchers and practitioners in fields such as geophysics, geohazards, and environmental monitoring. It enables the study of phenomena like subsidence, earthquakes, volcanic activity, and landslides by transforming raw SAR data into actionable insights about ground movement. Its open-source nature on GitHub fosters collaboration and continuous improvement within the scientific community.
