海洋地理信息跨域关联功能的设计与实现

Functional design and implementation for Cross-Domain linked marine geographic information

为提升多源异构海洋地理信息集成应用能力,以航海保障多维信息联动应用需求为例,介绍了"数字海洋基础地理信息平台"中相应解决方案:采取拆分、建库和重组的方法,实现了非结构化航海书表的空间关联;利用电子航海图数据动态生成三维模型,实现了航线仿真的三维关联;设计一种星球环形菜单三维视图多点触控方案,实现了人机交互的深度关联。所提方法已在实际应用中得到有效验证,并取得了良好应用效果。

In order to improve the integrated capability of multi-source heterogeneous marine geographic information, this paper focus on the linked application requirements for navigation, summarizes the corresponding solutions in the “Digital Marine Basic Geographic Information Platform”.First, the spatial link of unstructured navigation books and tables is realized by using the methods of splitting, database building and reorganization;Secondly, the real electronic chart data is used to dynamically generate the three-dimensional model and realize the three-dimensional link for route simulation;Thirdly, a menu with planet icon and ring shape is designed, a multi touch scheme for 3 D view is constructed, and the intelligent link for human-computer interaction is realized.The methods proposed in this paper have been effectively verified in practical application and achieved good application results.
