- GIPSA-Lab, Grenoble, France (M. Gay)
Summary
With the launch of new satellites and the development of multi-temporal SAR image processing techniques, we are at a turning point in the exploitation of SAR data for measuring surface deformations (volcanoes, faults, glaciers, etc.). The French method development (INSIS, INS2I) and user community (INSU) must adapt to this considerable data flow by reworking and distributing its software (documentation, automation, distributed computing) and increasing its computing and storage capacities.
Software development
– NSBAS chain
– EFIDIR tools
Summary
As new satellites with radar imagery capabilities are being launched and methods to process large stacks of SAR images are being developped, we are at a turning point towards systematic SAR data exploitation for surface deformation measurement (volcanoes, faults, ice caps, ...). The french community that develops data processing methods (INSIS, INS2I) and exploits deformation measurements (INSU) must adapt to the very large data flow. It must improve and distribute its software (documentation, automation, distributed processing) and increase its capacities to process and stock the data and its derivative.
