摘要
为提高海洋GIS分析效率,使系统分析模型更简洁、更具领域特性,在分析相关针对GIS建模研究的基础上,利用UML的扩展机制,定义针对海洋GIS的面向对象建模语言UML-M。描述UML-M的元模型,研究基于UML-M的空间对象和空间关系的模型表现方法,包括简单空间对象、覆盖对象、复杂空间对象、时空对象等。实例分析表明,UML-M可以很好地应用在海洋GIS中。
In order to improve the efficiency of analysis on marine geography information system （GIS）, and make the models be more sententious and get more domain characteristics, this paper defined an object oriented modeling language UML-M （Unified Modeling Language--Marine） for marine GIS by UML and its extension mechanism, based on the analysis of GIS modeling by other scholars. It described the meta--model of UML-M,and also researched the representation method of spatial object and spatial relation using UML-M, which including simple spatial object, coverage object, complex spatial object and spatial--temporal object. Finally, it has been proved that UML-M can be efficiently used in marine GIS by analysis on cases.
