摘要
提出使用Google Earth进行PS-InSAR形变成果展示的方法,并以成都部分PS-InSAR监测成果数据作为示例,构建了KML（keyhole markup language）文件,基于Google Earth三维场景进行了展示。结果表明,相对于传统二维地图的展示方法,新方法能够进行监测成果的三维展示,同时通过用户交互操作,可以查看相应PS点累积形变量变化信息,能够更全面地展示PS-InSAR监测成果,具有更好的展示效果。
In this paper,we study a method of using Google Earth to display PS-InSAR deformation results,and taking PS-InSAR monitoring data of Chengdu as demo data to construct KML files,then the result is displayed using 3D scene based on Google Earth.Results show that,compared with the traditional 2D map display methods,the method of our proposed can display the monitoring results in three dimensions and can also view the corresponding PS cumulative deformation change information,so it can be more comprehensive in displaying PS-InSAR monitoring results,and has better display effect.
