InSAR Suite QGIS 4 compatibility

InSAR Suite is an integrated QGIS plugin that brings together six 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 SAR data into East-West and Up-Down components, with automatic resampling grid creation (square or hexagonal cells). 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. Output can be saved as a permanent GeoPackage. - InSAR TS: time series analysis tools including data quality and homogeneity check (with skewness and kurtosis), automatic kinematic analysis, seasonal decomposition (STL), piecewise non-linear analysis, temporal anomaly detection, and multi-zone comparison. Supports DYYYYMMDD and YYYYMMDD date field formats. - InSAR Polygons: automatic delineation of deformation areas from PS data using buffer and geometric dissolve by velocity class, with hierarchical clipping and optional morphological smoothing. Output can be saved as a permanent GeoPackage. - InSAR Report: generates a PSI summary sheet for a study area (hand-drawn, loaded from a polygon file, or picked from a layer already in the project), with PS count, density, areal coverage, kinematic coherence, mean visibility and velocity ± standard deviation for both ascending and descending datasets, plus the mean EWUD vector (angle ± circular standard deviation, velocity, E, U components ± standard deviation), all automatically filtered to the study area. Exportable as PNG or CSV.
