拓扑关系是GIS进行空间推理、查询和分析的基础.多边形之间的拓扑关系应用是较为广泛的GIS应用之一.目前多边形的拓扑关系一般都针对简单无洞多边形而言,而目前对多边形空洞的去除没有一个很好的办法,本文利用ArcGIS的VBA,开发算法去除多边形空洞.经试验表明,该方法简单、效果理想.

@@@@The spatial topological relationship is the key in the relationships of GIS, which plays a very important role in the process of spatial reasoning, spatial querying as well as spatial analysis. The topological relationship between polygons is a popular issues in GIS applications. As we known, the topological relationships between polygons means the polygons have no holes. Now there is no a good methods to remove the holes from polygon in our GIS software. In this study, the method of how to remove holes from polygon was detailed and applied for experiment.
