海洋地理信息系统研究进展

Research progress of the marine geographic information system

海洋地理信息系统能够对海洋数据和信息进行高效地存储、管理、分析、显示和共享,可以大大提高海洋数据的使用率和工作效率,其研究和应用日渐受到人们的重视。在此背景下,重点从海洋地理信息系统理论构成体系,即从时空数据模型、时空场特征分析、信息可视化及信息服务4个方面回顾了近年来海洋地理信息系统研究工作,探讨了当前研究的不足和发展前景。时空数据模型研究未来将更多地强调时间维拓展和尺度变化的适应性方面;时空场特征分析会将海洋过程纳入其重点考虑范畴;海洋信息可视化将更加面向体验和跨尺度,并更多地将虚拟技术与真实现实结合起来;信息服务方面则会强调服务的智能化,注重海洋信息本体或知识表达问题,追求主动数据生成和提供。

Marine geographic information system （MGIS） can realize high efficient storage, management, analysis, display, and share for marine data and marine information. For such reasons, its research and application have attracted increasing attention. In this context, we focus on discussing the theoretical system of the marine geographic information system. We＆#39;ve reviewed the recent work in the research of the marine geographic information system from four aspects, namely Temporal Data Model （TDM） , Temporal Field Characteristics Analysis （TFCA） , Marine Information Visualization （MIV） , and Marine Information Services （MIS） . We also discuss the weakness of the current research and its development prospects. In the future work, Temporal Data Model （TDM） will emphasize on the extension of the time dimension and the adaptability of scale changes; Temporal Field Characteristics Analysis （ TFCA） will bring in marine processes as one of its key consideration scopes;Marine Information Visualization （MIV） will be oriented to the experience of the people and cross-scale, integrating with the virtual reality technology;Marine Information Services （MIS） will emphasize on the intelligence services pursuing the initiative data generation and delivery.
