Measuring ground deformation is crucial in many fields of Earth sciences (eg. glaciers, landslides or tectonics) to understand the environmental forcing at work. In this work, we present the processing chain Multi-Pairwise Image Correlation for OPTical images (MPIC-OPT) to compute the ground displacement [1]. The chain is accessible on-line through different platforms (Geohazards Exploitation Platform -GEP- and For M@Ter webservice) allowing an easy access High-Performance Computing (HPC) infrastructures and currently ingest Sentinel-2 L1C data. The application of the method is presented for three use cases: a) to measure the co-seismic displacement of the Palu, Sulawesi (Indonesia) 2018 earthquake, b) to monitor ice velocity of the Khumbu glacier (Nepal), c) to monitor the ground displacement of the Slumgullion landslide (USA). |
