摘要 当前大多数时空数据处理与可视化工具在数据规模增大时不能够对数据进行快速地处理与可视化.为解决该问题,通过对任务模型、数据模型及可视映射策略的重新定义,给出一种大规模时空数据处理与可视化平台.平台能够支持多种不同类型的时空数据,通过分布式的数据存储、数据重新组织、分布式检索、空间索引、分段预取等技术,能够实现大规模数据的快速处理与可视化. Most of the existing spatio-temporal information visualization toolkits cannot process and visualize data efficiently when the size of the data is too large.In this paper,we present a visual analytics platform that supports large-scale spatio-temporal data.By redefining task model,data model,and visual mapping strategies,this platform supports processing and visualizing many kinds of big data with spatio-temporal attributes.The processing and visualizing can be done in seconds by distributed storage,data reorganization,distributed query,spatial indices and segmented fetch,even though it has a terabyte of data.
