| 摘 要： | 介绍了一种基于图像膨胀算法实现矢量数据缓冲区分析的新算法。该算法将地理实体栅格化后依据用户指定的宽度，反复交替使用8连通膨胀与4连通膨胀，直至达到指定的宽度为止，最后提取出膨胀后图像的边界。该算法具有思路简单，算法稳定，易于实现的特点。

| Abstract: | A new algorithm for creating a buffer zones based on algorithm of dialation is introduced. The geographical entity is made into raster by the algorithm and carried out 4 accessibility dilation and 8-accessibillty dilation alternatively, which continues to be expanded until this width reach the width of designation. There are some characteristics of the algorithm such as being easy to realize and so on. |
