智慧城市时空数据三维可视化设计与关键技术

Design and Key Technologies of 3D Visualization for Spatio-temporal Data of Smart City

随着数据内容的不断增加,特别是新型测绘产品数据的扩展延伸,智慧城市时空大数据的三维可视化面临着新的机遇与挑战。针对时空大数据三维可视化所面临的数据集成、数据组织优化以及资源合理分配等问题,设计了面向三维可视化的时空大数据集成内容及其相应框架,并针对数据集成存储、细节层次构建和计算资源调度等关键技术开展了研究,为构建多源、高效的智慧城市时空大数据平台奠定了三维可视化基础。

With the continuous increase of data content,especially the expansion and extension of new surveying and mapping product data,3 D visualization of spatio-temporal big data in Smart City is facing new opportunities and challenges.Aiming at the problems of data integration,data organization optimization and resource allocation faced by 3 D visualization of spatio-temporal big data,we designed a framework of spatio-temporal big data integration for 3 D visualization,and studied the key technologies,such as data integration storage,LOD construction and computing resource scheduling.This study can lay the 3 D visualization foundation for the construction of multi-source and efficient spatiotemporal big data platform of Smart City.
