融合多源数据的地表变形监测平台研究

Research on Surface Deformation Monitoring Platform with Multi-source Data Fusion

对变形监测结果进行可视呈现与表达,能够为专业人士提供可靠的辅助与决策依据,在智慧城市规划、城市灾害监测、城市灾害预警方面发挥着积极作用[1]。本文结合GPS和InSAR技术对山西省大同市部分地区进行了地表变形监测,并在B/S架构下集成了三维地理空间平台Cesium,实现了大规模监测数据的加载与显示,同时结合图表等方式进行统计分析与可视化,通过变形阈值设置完成在线预警功能,构建了一个多源、多尺度、多功能的变形监测平台。

Visual presentation and expression of deformation monitoring results can help professionals provide reliable assistance and decision-making,and play an active role in smart city planning,urban disaster monitoring and urban disaster early warning.This paper combines GPS and InSAR technology to monitor surface deformation in some areas of Datong city,Shanxi province,and integrates the 3D geospatial platform Cesium under the B/S architecture to realize the loading and display of large-scale monitoring data.At the same time,statistical analysis and visualization are carried out through charts and other methods.The online warning function is completed through deformation threshold setting,and a multi-source,multi-scale,and multi-functional deformation monitoring platform is constructed.
