| 摘要: |
| 基于海洋环境要素数据多源的特点，三维地球的可视化显示更有利于海洋复杂信息传递。Cesium是一款免费、拥有诸多API（application programming interface）的开源地图引擎，本文将二维可视化渲染效果较好的点方式可视化法、点图标映射法和流线法应用在Cesium三维地球引擎中，以NetCDF数据格式为例，实现了基于Cesium开源地图框架的海洋环境要素可视化，直观形象地模拟了真实海洋环境。 |

| Abstract: |
| The 3D visualization of the Earth can conveniently transfer complex information on the basis of multisource marine environment data. Cesium is a free, open-source map engine with many application programming interfaces. In this study, point mode visualization, point icon mapping, and streamlines are applied in Cesium, and the network common data form format is taken as an example to realize the visualization of marine environmental elements based on Cesium. The final results simulate the real ocean environment intuitively. |
