This new general-purpose data archive format is network-transparent, i.e, machine-independent and has been implemented in terms of XDR (eXternal Data Representation). We test this format by using EFIT (Equilibrium Fitting) code on different operation systems, namely Linux and Windows, different processors, namely Sun and Pc, and different programs, namely in Fortran and C language. It can be easily used by different computers and different programming languages.展开更多
为了实现叶绿素a浓度数据的三维动态可视化效果,针对海洋环境数据多维、多时间及多格式等特点,在全面分析NetCDF(network Common Data Form)数据模型的格式、存储的基础上,结合GPU(Graphics Processing Unit)与osgEarth三维地球虚拟场景...为了实现叶绿素a浓度数据的三维动态可视化效果,针对海洋环境数据多维、多时间及多格式等特点,在全面分析NetCDF(network Common Data Form)数据模型的格式、存储的基础上,结合GPU(Graphics Processing Unit)与osgEarth三维地球虚拟场景,提出一套海洋环境中叶绿素a浓度的动态可视化方法。实验表明,该方法具有一定的可行性和高效性,为海洋环境数据的动态可视化与分析提供了强有力的可视化平台。展开更多
