海洋信息网格服务平台的设计与实现

The Design and Implement of Marine Environmental Information Grid Platform

本文针对海洋信息的分布性、信息类型及格式的多样性、数据的海量性,以及数据处理的计算量大等特性,对地理信息系统、网格技术、Web服务技术,以及远程可视化技术等进行了综合研究。首先,探讨了海洋信息网格服务平台构建的关键技术,包括海洋信息网格技术、网格环境下海洋信息的集成方法,以及远程可视化技术,并提出了海洋信息网格服务平台的系统架构;其次,选定南海海域为实验区,以Argo数据、海温和海流数据为实验数据,实现了海洋信息网格服务平台原型系统。该平台可以集成异构、分布式环境中的数据服务和应用服务,为用户提供透明的、"一站式"的海洋环境信息Web应用。该系统为海洋用户充分利用各种海洋环境信息,提高海洋工作的效率,减少重复性投资、充分合理利用现有设备和资源提供了借鉴。同时实验表明,本文所提出的技术路线是可行和正确的。

In view of the distribution of massive marine environment information,the multiplicity of information type and format as well as complicated procedure,by researching the geographic information system,the grid technology,the Web service technology as well as the remote visualization technology,firstly,this paper has discussed the system construction and key technologies of the marine environment information grid service platform.Secondly,the prototype system of marine environment information grid service platform has been realized,taking the Argo data,the sea surface temperature data and the Sea Flow Field data as the empirical data,and taking the South China Sea as the experimental zone.The experimental environment consists of three web services nodes,a web services resource management center and an application service platform of marine environment information in the South China Sea.Node 1（provide web services of Argo data and sea flow field data）,node 2（provide web services of sea surface temperature data） and node 3（provide web services of application models） and the application service platform of sea surface temperature information are arranged in the Institute of Geographic Sciences and Natural Resources Research,Chinese academy of science.The web services resource management center is arranged in the Northeastern University.This prototype system has provided reference for users on making full use of each kind of marine environment information and existing equipment,improving work efficiency and reducing duplicated investment,solving the problems in heterogeneity,distribution,and efficiency triggered by networking,and providing users with transparent,＂One-stop＂ Web applications on marine environment information.On the platform,heterogeneous and distributed marine environment is encrypted,decrypted and monitored,and hence interchangeable according to international standards.Simultaneously the feasibility and practicality of the above technical solution has been well tested.
