摘要: Persistent scatterer interferometry (PS-InSAR) is a common technique used in surface motion estimation. However, it is not easy to fully analyse the results, especially for non-experts. Due to the complexity of the formation of Persistent Scatterers (PS) points as well as the large difference in scale and time-series characteristics, it is necessary to develop new visualization methods for a better understanding and analysis of PS-InSAR data. In this article, we implement a dynamic online visualization for PS-InSAR surface motion estimation results using WebGL. A 3D interactive visualization method gives users vivid experiences with interactive operations so that they can easily observe scene details. Animation is used to show the development of surface motion over time as estimated using PS-InSAR, presenting results in an intuitive way through scientific visualization methods. Online visualization through our application makes PS-InSAR results accessible and relevant to dispersed users from diverse domains.
