摘　　要：在分析海洋观测数据三维可视化必要性的基础上,提出在海洋GIS中集成海洋数据三维可视化功能是解决当前海洋观测数据信息深层次挖掘难题的关键。对海洋观测数据三维可视化关键技术,包括三维可视化开发技术、海洋要素场数据模型、海洋要素场三维可视化流程、离散观测数据内插方法等,进行了系统分析。此基础上,根据海洋观测数据的特点,选择OpenGL和IDL作为三维可视化开发技术,采用C++和VC++语言开发用于海洋观测数据处理、分析的三维可视化组件CMa3DView,并集成到自主研发的海洋GIS系统——MaXplorer中。实际应用表明,基于提出的海洋观测数据三维可视化方法能较直观的再现复杂的海洋环境,从而为海洋科研工作者揭示抽象数据变化规律以及理解、分析各种复杂海洋现象,提供强有力的辅助工具。The view integrating three-dimensional（3D） visualization of marine data into the marine GIS is the key to resolve problems in deep data mining of marine measured data information.And then,the key technologies of 3D visualization with marine measured data were analyzed,including developing technologies of 3D visualization,the marine feature field model,the 3D visualization flow of marine feature fields,and the interpolation methods of discrete data.According to the characteristics of marine data,OpenGL and IDL were selected as the 3D visualization developing technology.On basis of the above-mentioned study,the 3D visualization component named CMa3DView was developed using the C＋＋ and VC＋＋ language that used for marine measured data processing and analysis,and integrated it into the self-developed marine GIS——MaXplorer.Practical application shows that 3D visualization methods of the marine measured data could be more intuitive representation of complex marine environment,so it provided a powerful tool for marine scientific workers to reveal the rules of abstract data and analyse the complex oceanic phenomena.
