云模式下地理空间数据管理及更新机制研究

Research on Geospatial Data Management and Updating Mechanism in Cloud Mode

本文针对湖南省多源异构地理空间数据分散管理及更新频率低等问题,提出在云模式下基于"多库一体"的管理架构,统一集成管理地理空间数据,通过原始库、母库、临时库联动,按需更新,并成功应用到湖南省地理信息公共交换共享平台大数据管理中心的建设中,事实表明该研究成果理论先进,方法可行。

This paper aims at the problems of long decentralized management and low frequency updating of multisource heterogeneous geospatial data in Hunan province, and proposed to manage the geospatial data unified in the cloud model based on "multi-library integration" management structure. The above framework is updated on demand through the linkage of the original library, the mother library and the temporary library, and this is successfully applied to the construction of the big data management center of the Hunan Provincial Geographic Information Public Exchange and Sharing Platform. The facts show that the theory of the research results is advanced and the method is feasible.
