大数据与广义GIS

Big Data and Generalized GIS

  • 摘要: 目的 普适计算基础设施和数据处理技术的发展催生了大数据概念,而大数据时空粒度的不断细化加速了地理空间信息的泛化过程。阐述了大数据时代地理空间信息泛化的显著特征,进而提出GIS概念广义化的迫切需求,从数据采集与整理、数据管理与集成、数据分析与计算三个方面分析了广义GIS所面临的技术挑战,重点探讨了互联网蕴含地理空间数据采集、移动对象数据库和异构动态数据管理、移动对象轨迹数据挖掘、复杂网络分析等方面的研究进展与存在的问题,并展望了广义GIS时代地理计算与城市计算、社会计算的融合趋势。

     

    Abstract: Objective The development of an ubiquitous computing infrastructure and data processing technologiesare giving birth to big data,and the continuous refining of the spatial-temporal granularities of big da-ta speeds up the generalization of geo-spatial information.In this paper,the distinctive characteristicsof generalized geo-spatial information are investigated,and the urgent need for a more generalized con-cept of GIS are clarified.Then the technical challenges for general GIS are set forward in terms of datacollection and cleaning,data management and integration,and data analysis and computing.The pro-gress is summarized and the research issues are discussed in geo-spatial data collection with Internettext mining,moving object database,dynamic and heterogeneous data management,moving trajectorydata mining,and complex network analysis.The fusion of geocomputation,urban computing and so-cial computing in the near future is considered at the end of the paper.
