| 摘 要： | World Wind是由美国宇航局(NASA)开发的三维地理信息系统,也是一款可提供丰富数据的数字地球平台,如何将多源数据实现紧密型二三维耦合是基于World Wind开发专业系统需要解决的重要问题.在.NET开发环境下,以World Wind为仿真内核,开发了水位仿真系统,研究了二三维数据耦合技术,实现了环鄱阳湖生态经济开发区的湖区与航道淹没分析和三维漫游.结果表明,仿真系统流畅地实现了任意点地形高程、水位、水深和航道级别等信息的实时查询,仿真了不同控制水位条件下的鄱阳湖区淹没范围,仿真结果能够服务于鄱阳湖水利枢纽的水位调控决策；该仿真系统在湖泊干旱特征水位等确定中也具有重要的应用价值. |

| Abstract: | World Wind is an open source(released under the NASA license) virtual globe developed by NASA.The program provides a platform for digital earth and 3D GIS.The realization of the compacted 2-3D coupling of multi-source data is one of the problems in the process of developing professional system based on World Wind.In the.Net development environment,taking World Wind as the simulation kernel,the authors developed the water level simulation plug-in,studied the 2-3D coupling of data technology,and realized the lake & channels’ flood inundation risk analysis and 3D roaming of the Poyang ecological economic development zone.The results show that the simulation system can realize smoothly the real-time information query at any point in such aspects as terrain elevation,water level and submerged depth,and navigation level.The submerged range of the Poyang Lake is also simulated under different water-control conditions.The results can serve the decision-making regulation of Poyang Lake water conservancy hub. |
| Keywords: | simulation of Poyang Lake’s water level control water submerged scope Poyang Lake World Wind GIS |
