用Voronoi方法为MapInfo扩展拓扑功能

Using Voronoi Approach of Developing Topological Functions in MapInfo

分析了Ｖｏｒｏｎｏｉ图在表达邻近关系方面的特性，提出了用Ｖｏｒｏｎｏｉ方法为ＭａｐＩｎｆｏ建立动态邻近关系并扩展拓扑功能的方法。

Neighbor relationship can be expressed by the Voronoi Diagram easily.Based on this attribute,the paper advances an approach to constructing neighbor relationship and developing topological functions in MapInfo.
