| 摘 要： | 缓冲区分析是地理信息系统重要的空间分析功能之一.本文对线状缓冲区算法做了进一步改进,提出一种基于轴线转折点旋转生成线状缓冲区的算法,简化了线状目标缓冲区边界的生成过程,较好地解决了双线的等宽性.最后用实验数据对算法进行了测试,结果表明算法是可行的.

| Abstract: | Buffer analysis is one of the several important analysis functions of geographical information system(GIS).In this paper,an effective algorithm of generating linear buffer based on rotation transform point of polyline is proposed,which further improves the algorithm presented by LI Zhigang,simplifies the process of generating borderline of linear buffer,and finds a better solution to the equal width of double parallel line.Finally,it tests the algorithm by using empirical data. |
