海洋环境时空过程数据多维表达技术研究

Research on Multidimensional Expression Technology of Ocean Environment Spatiotemporal Process Data

时空动态过程是海洋的重要特征,海洋数据的多维表达是海洋环境时空过程要素和现象的空间认知与知识挖掘的重要研究内容。传统GIS很难分析和处理处于虚拟地理空间下以海洋大数据为载体的信息流动的虚拟海洋环境空间的复杂地理要素与地理现象。本文从虚拟海洋环境和抽象坐标海洋空间环境相结合的角度,提出了基于数字地球模型的虚拟海洋环境构建方法,实现了基于抽象坐标系统的海洋实体空间对象数据和虚拟海洋生态环境对象数据的一体化集成;设计了一维、二维海洋环境数据时空过程表达技术方案;研发了三维海洋环境时空动态数据结构与过程表达计算引擎,实现了海洋环境要素场的单层要素场过程和多层动态过程模拟等多维表达方式。最后,结合我国智慧海洋建设,提出了关于未来发展方向与研究重点的认识与建议。

coordinate system and the object data of virtual ocean ecotope were integrated,and we designed a spatiotemporal process expression scheme for one-dimensional and two-dimensional data of ocean environment.Secondly,the computing engine for three dimensional ocean environment dynamic data structure and process expression was developed,and the multidimensional expression of single factor field and multi-layer dynamic process simulation of ocean environment factor field were realized in this paper.Finally,combined with the construction of intelligent ocean in China,the future development direction and research emphasis were put forward.
