Abstract: Using interferometric SAR technology the surface deformation field along LOS can be achieved. In order to get some geometric or kinematic parameters about the earthquake-triggering fault, a comparison between the surface deformation field along LOS acquired by D-InSAR technology and the calculated surface deformation based on Okada model can be done. This kind of method has been proved successful. But it was done on PC, and because of the complexity of all the processes that this method needed, including program's testing and installation, it's nearly impossible to implement this method and the corresponding programs on needed computers. And it's an overwhelming job and it's not an economic way to do the job. With the financial support from MOP and its internet environment improving project, we develop a system called remote-modelling system for InSAR co-seismic deformation. In this article, we introduce the whole process of the transferring from PC program and method to remote calculation. In order to testify the system's stability and compatibility, we also do a case study about an earthquake surface deformation.
