摘　　要：针对在海图的应用中 ,由于实际地理信息的多样化和海量化特点以及海洋信息的特有性质导致运用传统的制图综合方法无法很好地解决海图自动综合问题 ,对MarcvanKreveld提出的制图综合中的 1 2个问题进行了研究 ,总结海图制图综合常见情况 ,在充分考虑拓扑关系变化的基础上结合海图制图综合实际应用提出改进方案 。In chart application, diversification and magnanimity of real geographic information and special characters of ocean information cannot be resolved by traditional map generalization methods. This paper researches on the twelve computational geometry problems advanced by Marc van Kreveld and brings forwards improved methods. The change of spatial topological relations and how to recover these topological relations through studying the change of objects geometrical relation are studied. Twelve approaches hav...
