【摘要】 GIS与云计算的结合为GIS的数据存储、管理、处理及其应用提供了一个新的发展前景.分别给出了云计算和云GIS的定义,提出了云GIS的四种应用模式和一个多层次架构模型,重点研究了云GIS的关键技术:虚拟化技术、分布式数据存储技术(GFS)、虚拟化数据管理技术(Bigtable)、并行空间分析技术、数据和功能互操作技术和部署模式,最后给出了一个云GIS实际应用框架.更多还原

【Abstract】 The combination of GIS and clouding computing provides an extensive development prospect for GIS information storage, management, processing and application. The definition of cloud computing and cloud GIS are presented, four application mode and a multi-level architecture model of cloud GIS are proposed. The key techniques, such as virtual technology, distributed data storage technology(Google File System), virtual data management technology(BigTable), parallel spatial analysis technology, data and functional interoperability technology as well as deployment model are mainly studied. Finally, an actual application framework of cloud GIS is given.更多还原
