InSAR Suite is an integrated QGIS plugin that brings together four tools for PSI (Persistent Scatterer Interferometry) data analysis into a single dedicated toolbar.
- InSAR Load: loads PSI point layers from GeoPackage, Shapefile or GDB files using a polygon index layer, or reactivates an index already present in the project.
- InSAR EWUD: decomposes LOS velocities from ascending/descending Sentinel-1 (or other SAR) data into East-West and Up-Down components, with automatic resampling grid creation. Outputs include Na and Nd fields (number of PS points used per cell).
- InSAR VIS: calculates the detectable movement percentage (pc_mov) based on SAR acquisition geometry and terrain morphology derived from a DEM.
- InSAR TS: time series analysis tools including data quality and homogeneity check, automatic kinematic analysis with mean series layer output, seasonal decomposition (STL), piecewise non-linear analysis, temporal anomaly detection, and multi-zone comparison.
