Amélioration et test d’une solution d’auscultation de terrain de champs de déformation complexes par intégration de données InSAR, GNSS et nivellement

Abstract : For the ground displacement study like subsidence, many types of measurement can be used like leveling, GNSS or InSAR. However, each of this method are likely to be affected by biases, more or less significant according to the geographical and meteorological contex. That’s why Fugro set up a geostatistical combination method. To improve this combination solution, an InSAR processing chain has been set up by using the ESA Copernicus program’s data. This processing chain use the software SNAP, scripts SNAP2STAMPS and the software StaMPS to obtain ground deformation velocity from a set of radar image. As the next step of this processing chain, a QGIS plugin has been developed to proceed with the geostatistical combination. This one allows to do the combination in a GIS and so set all combinations parameter and control all results according to the case study’s environment.
