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.地理信息系统中的缓冲区生成分点、线、面3种,线状目标缓冲区的生成是点、线、面3种基本空间要素缓冲区生成的关键和基础,文中就线状目标缓冲区的两种生成算法进行了严密的数学推导,并通过编程实现取得了较好的效果.
Buffer analysis is one of the several important spatial analysis functions of geographical information system （GIS）. In GIS, buffer generation can be divided into three types： points, lines and polygons. Because the buffer generation for linear objects is the key and basis of buffer generations of three basic types, then this paper carried on the strict mathematics inferential reasoning on the two algorithms of generating buffers for linear objects, and has obtained the good effect through the programming implementation.
