摘要
针对当前航标选取主要依靠经验和手工方法实施,选取时难以将航标各属性当成一个整体来考虑的现状,分析了航标空间属性的关联性,构建了航标的空间影响域模型,并探索了其在航标自动选取中的应用。实验结果表明:可以通过构建空间影响域模型来定量化表示航标的有效影响范围;空间影响域模型可以用来实现航标的自动选取。
To address the limitation of selecting aids to navigation in chart generation which mainly depends on experience and manual method and is difficult to take the features as a whole, the relevance of special features of aids to navigation is analyzed. Then the spatial influence domain model is constructed and its application in automatic selection is explored.The experimental results demonstrate that ： （ 1 ） the effective influencing area of aids to navigation can be expressed quantificationally by constructing the spatial influence domain model ; （ 2 ） the proposed spatial influence domain model can be used to achieve automatic selection of aids to navigation.
