Abstract

The aim of this paper is to propose a strategy able to provide 3D temporal evolution of ground deformations. To this end, for a given multi-temporal dataset of DInSAR (Differential Interferometric SAR) data and GPS measurements, a Grid infrastructure is used to perform parallel execution of the SISTEM (Simultaneous and Integrated Strain Tensor Estimation from geodetic and satellite deformation Measurements) method in order to estimate 3D ground deformation maps. Then a SBAS-like algorithm is used to merge the estimated static maps to provide a 3D temporal evolution of deformations over the whole investigated area.
