【摘要】：针对快速增长的地理空间数据为地理信息系统(geographical information system,GIS)在大数据时代的应用带来众多机遇和挑战,却一直缺乏系统论述的问题,在对大数据及地理空间大数据特征进行分析的基础上,通过若干典型实例展示了大数据与GIS耦合所带来的巨大应用,并分析了大数据时代对GIS数据采集、数据存储、数据处理和分析等诸多方面所带来的挑战,进一步指出引入概率论的数据筛选、分布式云存储和数据快速分析等数据分析技术与方法,是增强大数据时代中GIS与决策支持系统之间耦合度的着力点。
[Abstract]:The rapid growth of geospatial data has brought many opportunities and challenges to the application of Geographic information system in big data's time, but it has been lack of systematic discussion. On the basis of analyzing the characteristics of big data and the geographical space big data, this paper shows the great application of the coupling of big data and GIS through some typical examples, and analyzes the data collection and storage of GIS in the period of big data. The challenges of data processing and analysis, etc., further point out the data analysis techniques and methods, such as data filtering based on probability theory, distributed cloud storage and fast data analysis, etc. It is the key to enhance the coupling degree between GIS and decision support system in big data era.
