摘　　要：随着无人机和计算机的快速发展,遥感和GIS集成技术已成为国土资源调查和城市空间规划的重要手段之一。三维实景模型与二维数据相比可以更加直观地反映真实的三维世界。传统的WebGIS平台只能加载二维栅格和矢量数据,难以满足现阶段遥感监测的多维度需求。基于开源JavaScript库Cesium,采用B/S架构,创建一个可以集成展示二维数据与三维实景模型的轻量级WebGIS平台。通过该平台,可实现二三维视图联动显示、属性查询、空间定位等功能,能有效满足动态监测项目需要。With the rapid development of unmanned aerial vehicle(UAV)and computer,remote sensing and GIS integration technology has become one of the important means of land resources survey and urban spatial planning.Compared with 2D data,3D real scene model can reflect the real three-dimensional world more intuitively.The traditional WebGIS platform can only load two-dimensional raster and vector data,which is difficult to meet the multidimensional requirements of remote sensing monitoring at the present stage.Based on an open source JavaScript library named Cesium,using B/S architecture,it creates a lightweight WebGIS platform that can display 2D data and 3D real model.Through this platform,we can realize the functions of 2D and 3D view linkage display,attribute query,spatial positioning,etc.,which can effectively meet the needs of dynamic monitoring projects.
