| 摘 要： | 空间聚类是将空间实体根据某些相似的特性聚类成为一个集合,这个集合称为簇。本文研究了一种基于中心点距离的居民地面要素聚类算法:通过获取面状要素的数据,运用基于其几何中心的距离计算方法,判断面要素之间距离的可达性,并将距离小于阈值的面要素进行聚类,最终以凸包的形式将该集合绘制出来。本文的算法是在VS2010以及ArcGIS Engine开发环境下通过编程实现,并进行多组实验,实验结果表明,该应用程序可以实现居民地面要素的自动聚类。

| Abstract: | Clustering of residents is an important part of cartographic.Paper study a clustering of resident’s algorithm based on convex hull:input area patterns file such as residents,calculating the distance between area patterns.Give a threshold and determine the distance between the area patterns if the distance is less than the threshold will draw a convex hull on area patterns,finally complete the clustering of residents.The algorithm developed in VS2010 environment by ArcGis Engine secondary development application.The experiment shows that the application can realize automatic clustering of residents. |
