摘要
本文介绍了采用计算机数字化仪的点输入功能,将曲线数字化。通过程序处理,对原图进行缩放,绘制任意比例尺的图件。其特点是操作简便、工作效率高,能满足绘图精度要求。
It is introduced in this article that the curves are digitized by point input function ofcomputer digitization instrument,and then origin maps are reduced or extended by certain program todraw maps on arbitrary scale.This method is very simple,efficiency and can meet the precisional re-quest.
