摘要
分析了二维电子航道图和三维航道模型各自存在的优势和不足,提出了互相融合的多维数字航道模型.该模型在三维航道模型的水面上融合了标准的二维矢量电子航道图数据,方便进行航行状态、航线设计、船舶和航标管理中的空间计算和分析,在统一框架下很好地结合了二维电子航道图的宏观、精准、整体、简洁性和三维航道模型的局部、真实、直观的优点.最后,利用NASA的虚拟地球World Wind JavaSDK实现了多维数字航道模型,为多维船舶导航、船舶监控、航标遥测遥控等数字航道应用系统构建了一个基础平台.
This paper analyzes the advantages and disadvantages of both two-dimensional electronic navigation chart and three-di- mensional waterway model, and puts forward a new muhi-dimen- sional digital waterway model based on the integration of them. The model overlays standard two-dimensional vector electronic navigation chart on the water surface of three-dimensional water- way model to facilitate spatial calculation and analysis for naviga- tion, route plan, management of ship and navigation aid mark. In this way, the model can gain both advantages of electronic navigation chart and three-dimensional waterway model such as accuracy, reality and so on in a unified framework. This paper realizes the multi-dimensional digital waterway model through the virtual earth technology by World Wind Java SDK of NASA, and constructs a basic platform for multi-dimensional ship navigation,ship monitoring, pharos remote control and other digital waterway application systems.
