PyGMTSAR Brings Satellite Interferometry to Python and Google Colab
An open-source Python library for processing Sentinel-1 satellite radar data, from scene retrieval through interferometry, time-series analysis, and 3D visualization.
- For
- Satellite-imagery researchers and geospatial analysts
- Worth noticing
- Colab examples process Sentinel-1 scenes, DEMs, orbits, and up to 56 bursts for a Central Türkiye earthquake case.
Field notes
The homepage exposes a substantial remote-sensing workflow rather than a simple project description. Its notebooks handle data acquisition and preprocessing before interferogram generation, time-series analysis, and mapping, with examples spanning volcanic eruptions, earthquakes, flooding, and subsidence. A separate announcement describes InSAR.dev as a Zarr-based successor designed to separate SLC preparation from large-scale interferometric analysis.
