Context and contributions of the position

Joining the French Geological Survey (BRGM) means becoming part of France's leading public institution for Earth Science applications bringing together 1,000 wholeheartedly committed experts across 29 bases in Mainland and Overseas France.

BRGM focuses on enhancing geological knowledge and understanding of surface and sub-surface-related phenomena, with a view to: meeting the challenges of environmental changes through innovative projects with societal implications.

Interferometric Synthetic Aperture Radar (InSAR) and optical satellite image correlation are two essential methods for studying landslides due to their ability to provide precise measurements of ground deformations on a large scale and at regular time intervals.

These methods enable the mapping of ground movements, revealing deformation processes and providing insights into landslide kinematics.

By combining InSAR data with geophysical models, it is possible to characterise the mechanical properties of the landslide and identify factors contributing to terrain instability.

Job description

The project will involve:
- 1) The automation of InSAR processing chains and optical/radar image correlation, particularly the GAMMA chain (www.gamma-rs.ch);
- 2) The exploitation of time series of satellite images from the Copernicus program (i.e., Sentinel-1 and Sentinel-2) obtained through SAR Interferometry and SAR amplitude image correlation approaches, combined with ADA-type tool;
- 3) The integration of new CNES sensors (CO3D, Pléiades NEO, Ci3L) and off-the-shelf sensors (PLANET);
- 4) The familiarisation with the “ground deformation” tools provided by the PC Platform;
- 5) The comparison of InSAR/correlation results (e.g., velocities, locations, etc.) with those produced by the PC Platform tools: accuracy and field validation;
- 6) The application to landslides in the Pyrenees and the Alps.

Profile

Requested start date : 02/06/2025
Education : PhD
Experience : Beginner

You will demonstrate the following skills and abilities:

- SAR signal processing;
- Scripting/coding;
