摘要
等高线的机助绘制方法有二种:自动生成法;手工绘制法。自动生成的等高线由于受野外采集的数据和已有资料的影响往往会出现错误、失真、不美观。为了避免错误、失真和不美观的等高线出现,得到令人满意的能够表达真实地貌的等高线,就要对等高线进行恰到好处的处理。
There are two methods for computer c：ontour drawing, namely self- producing and manual operation. As some mistakes and distortions appear from the former method, the later method come into favour. The paper introduces the manual drawing operation.
