“数字海底”系统建模中的关键技术研究

Study on the key technology of "digital seabed" system modeling

基于“数字海底”系统的理论基础研究和在海底科学应用中的具体实践,提出了“数字海底”的涵义、系统组成和体系结构,对空间数据管理技术、基于XML的WebGIS空间数据表达技术、复杂海底三维建模技术、多源信息的一体化集成显示技术、虚拟现实技术等“数字海底”系统建模中的关键技术进行了探讨,为从事海底资源研究和开发的人员提供各个层次的参考或帮助.

On the basis of study of theoretical foundation of ＂digital seabed＂ system and the technical implementation in marine sciences, the meaning, composing and framework of the ＂digital seabed＂ system are presented. Some key technical questions of ＂digital seabed＂ system are discussed, for example, spatial database management technology, XML-based spatial database display technology of WebGIS, three-dimensional modeling technology for complicated seabed, integrative conformity and display technology of multisource information and virtual reality technology. It can provide multi-level reference and help for the people being engaged in the investigation and exploitation of the marine resources.
