摘要
在GIS中,点与多边形位置关系的判断是GIS的重点和难点之一,对于这种关系的判定有很多种方法,本文重点总结在矢量空间中目前常用的几种方法,这些方法都是基于空间的定量计算,最后对这些方法进行了比较.
The method to judge the relation between the polygon and point is one of the emphases and difficulty in GIS. There are many methods to judge it. This paper emphasizes on summarizing one of the methods,and this method is based on spatial quantitative count. Finally this paper compares these methods.
