| 摘 要： | MapObjects是广泛应用于GIS软件开发的组件,但它不能够独立支持空间拓扑关系,从而限制了它在空间分析方面的应用。为拓展MapObjects的空间分析功能,本文利用它提供的对图形对象的操作方法,实现了对九交模型中的空间线面拓扑关系的判断,且结果表明本文的实现方法正确可靠,具有一定的实用价值。

| Abstract: | MapObjects is widely applied to develop GIS software.However,MapObjects can't support spatial topology relation,which limits its application in spatial analysis.For expanding MapObjects' spatial analysis functions,the paper introduced 9-intersection model.According to its characteristics in computational model,it carried out differentiating spatial topological relations between a line and an area based on MapObjects.It is indication that this method is correct,reliable,and has some applied value. |
