摘要
讨论了地理信息系统(G IS)中两种常用的缓冲区分析算法,并比较了它们各自的优缺点,提出了一种基于栅格与矢量相结合的缓冲区分析算法,并利用VC++语言分别对点状、线状和面状目标进行了缓冲区分析算法的编程实现。
This paper discusses two kinds of buffer area analysis algorithms in common use in GIS, also compares their merits and shortcomings, and puts forward a kind of buffer area analysis algorithm that interblended grid and the vector adopted by the text, and makes use of VC ＋ ＋ the difference to carry on the programming realization of the buffer area analysis algorithm to the target that point, line and area symbol.
