摘要

本文的目的是提出一种能够提供地面变形的三维时间演变的策略。为此，对于给定的DInSAR(差分干涉SAR)数据和GPS测量的多时相数据集，使用网格基础设施来并行执行系统(同时和集成应变张量估计来自大地测量和卫星变形测量)方法，以估计三维地面变形图。然后，使用类似sbas的算法合并估计的静态地图，以提供整个研究区域的三维变形时间演变。

A Grid application to estimate 3D temporal evolution of ground deformation displacements

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.
