数字海洋中海量多源异构空间数据集成研究

针对目前海量多源异构空间数据在组织、管理、集成方面的困难以及传统方法在数据转化过程中造成的数据损耗等问题,结合海洋空间数据的特征,提出一种新的海量多源异构空间数据无缝集成技术(SIMMHS)。该技术针对底层海洋空间数据的海量性和异构性,利用FLEX和XML技术,以XML为数据转换格式,使用XML Schema建立了公共模型,利用虚拟空间数据搜索引擎作为中介实现平台,实现了对海量多源异构空间数据的无缝集成。结合数字海洋上海示范区建设项目的实际应用,有效集成了海量多源异构的空间数据,以方便用户的快速浏览查询、系统的三维展示和数据的实时更新。

Integration of massive multi-source heterogeneous space-time data in digital sea

Currently,for the massive multi-source heterogeneous space-time data organization,management,integration difficulties,traditional methods in the data conversion process and other issues caused the data loss,combined with the characteristics of space-time data,this paper presented a new seamless integration of massive multi-source heterogeneous space-time data technology(SIMMHS).The underlying technology for the mass of space-time data and heterogeneous was used FLEX and XML technologies to XML format for data conversion.XML Schema was used to establish a public model,and Virtual Spatial-time Search Engine as an intermediary to achieve platform,realized the massive multi-source heterogeneous seamless integration of space-time data.With the practical application in Shanghai digital ocean demonstration area,integration of the massive multi-source heterogeneous space-time data in effect,facilitate the users browse and query quickly,realized the three-dimensional display of system and real-time update.
