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。通过对单一目标缓冲区的生成进行研究,给出了单一目标缓冲区自动生成的一般方法和算法。文末对特殊目标如目标本身自交情况和目标内含有若干孔洞的情况进行了讨论。
Buffer analysis is one of the several important analysis functions of geographical information system (GIS). This paper presents the common method and algorithm of automatic buffer generation for an arbitrary single object through the research of buffer generation for single object. At last, this paper discussed the method of buffer creation for special objects, for example, self-intersect of object and that contains several holes.
