基于NetCDF数据模型的海洋环境数据三维可视化研究

Visualization of marine environment data based on NetCDF data model

针对海洋环境数据多维、多格式及动态性等特点,本文在全面分析NetCDF数据模型的原理、数据组织及其调度方法的基础上,基于大范围三维虚拟场景,设计了符合NetCDF标准典型海洋环境要素的三维动态渲染模型,实现了海洋环境要素数据的三维动态可视化表达与分析。实验表明,本文方法为复杂海洋现象的表达、变化规律分析以及趋势预测等研究提供强有力的可视化辅助工具。

For the characteristics of muhi-dimensional, muhi-format, and dynamic with the marine environmental data, on the ba- sis of comprehensive analysis on the NetCDF data model in principle, data organization, scheduling methods and so on, the paper de- signed a 31） dynamic rendering model for typical marine environmental data which follows NetCDF standards, implenlented the repre- sentation a,d analysis of marine environmental data with three-dimensional and dynamic based on three-dimensional virtual scene. The experiment showed thai the method of this paper cotdd provide a powerful auxiliary tool for the representation of the complex ocean phe- nomena, spalial-temporal analysis and trend prediction.
