摘要
为方便时空大数据的交换与共享,满足对于专题数据、感知数据等数据量不大、更新频率较高的数据汇聚的实时性,通过对时空大数据分析和梳理,构建了时空大数据交换系统的总体框架,并完成了该交换系统的设计与实现。该系统实现了跨地区、跨单位应用系统之间的信息资源交换,完成了多源异构异的各类型信息资源交换与接入。
In order to facilitate the exchange and sharing of big data in space and time,it satisfies the real-time performance of data aggregation with small amount of data such as thematic data and perceptual data and high update frequency.Through the analysis and combing of spatio-temporal big data,a spatio-temporal big data exchange system is constructed.The overall framework and the design and implementation of the switching system.The system realizes the exchange of information resources between the inter-regional and inter-unit application systems,and completes the exchange and access of various types of information resources with multiple sources.
