摘　　要：随着地理信息技术的快速发展,获取的三维数据越来越多,传统的二维GIS平台已无法满足实际的应用需求。本文基于开源的Cesium框架,设计并开发了多源三维数据可视化与分析平台,实现了倾斜摄影测量模型、建筑体块模型、人工设计模型等多种三维数据的集成展示,并实现了三维数据的空间量测、光照分析、建筑模型单体查询等空间分析功能。平台已成功应用于实际的三维数据可视化与分析项目,用户体验良好。With the rapid development of geography information technology,a large volume of 3D data can be obtained,and thus the traditional 2D geography information system(GIS)cannot meet the current application need.This study designed and developed a platform for multiple 3D data visualization and analysis based on Cesium.Various 3D data such as oblique photogrammetry data,building block model,and artificial design model can be visualized in the platform.In addition,the platform achieved some essential function for spatial analysis including spatial measurement,sunshine analysis,and building information query.The platform has been successfully applied to the real projects for 3D data visualization and analysis with a good user experience.
