数字海洋水体模型建立与三维可视化技术研究

Research on the model building of water and 3d-dimensional visualization in Digital Ocean

在分析数字海洋水体要素信息表达需求基础上,提出了"水体立方"数据模型及其建立方法;基于Terra Suite、Ev-Globe等三维地理信息软件,研究了海面模拟、水体要素立体表达和海洋虚拟场景建立,其中通过"像元体"表达三维水体要素是本文的重点。该研究对数字海洋原型系统建设有技术指导作用。

On the basis of requirement of water information presentation of the digital ocean system, a method for cubic water data modeling and building is proposed. Based on the 3DGIS software package, such as Terrasuite and EV-Globe, sea surface modeling, water information presentation, and virtual ocean scenery building are studied, especially, the presentation of water feature with ＂cubic grid＂. The study brings new thoughts for the building of the digital ocean prototype system.
