【摘要】:"大数据时代"的到来,正在改变着人们的工作、生活和思维方式。该文较全面地分析了目前大数据及其应用的研究现状,提出"时空大数据"的概念,并认为时空大数据就是时空数据与大数据的融合,并从大数据与时空大数据的背景、特征、本质和类型,分析了时空大数据带来的科学范式、时空信息传输和认知模型等方面的变化,同时对时空大数据的理论体系、技术体系和产品体系进行了探讨。
[Abstract]:The arrival of big data's time is changing the way people work, live and think. This paper comprehensively analyzes the present research situation of big data and its application, puts forward the concept of "spatio-temporal big data", and thinks that spatio-temporal big data is the fusion of spatio-temporal data and big data, and from the background and characteristics of the spatiotemporal and spatial-temporal big data, the paper puts forward the concept of "spatio-temporal big data". In this paper, the changes of scientific paradigm, space-time information transmission and cognitive model brought by space-time big data are analyzed, and the theoretical system, technical system and product system of spatio-temporal big data are discussed.
