三维时空大数据政务服务系统建设研究

The research on the construction of a 3D spatial-temporal big data government service

三维时空大数据政务服务系统是集地理信息数据服务、三维时空大数据可视化渲染、政务专题信息等多方面内容为一体的全流程综合性地理信息服务系统。系统充分利用了云服务模式、B/S框架、Cesuim引擎、域名分片、矢量切片等技术,通过大数据可视化渲染、三维场景叠加、数据模型加载等数据集成方式实现了对现实世界的实景再现,为实景三维建设提供了基础数据服务和信息集成技术支撑。该系统提供了地理信息公共服务的多维度、多层次的应用能力,为辅助政府决策提供了强有力的数据支撑。

The 3D spatial-temporal big data government service system is a full process comprehensive geographic information service system which integrates geographic information data service,3D spatial-temporal big data's visualization rendering,government thematic information and other aspects.The system makes full use of technologies like cloud service mode,B/S framework,Cesuim engine,domain sharding,vector tile and others,and realizes the realistic reproduction of the real world through data integration methods,such as big data visualization rendering,3D scene overlay,data model loading,which provides basic data services and information integration technology support for the construction of 3D real scene.This system provides multidimensional and multi-level application capabilities for geographic information public services,and also provides strong data support for assisting government decision-making.
