本文简要叙述了数字制图定义、传统的１：５万地质图制作工艺流程，ＭＡＰＣＡＤ计算机制图系统的组成及功能。重点介绍了１：５万地质图计算机制作工艺流程和方法，并与传统的１：５万地质图制作方法作了比较分析，最后指出计算机制图最终将取代传统手工地图制图。 This article briefly describes the definition of digital mapping, the traditional 1: 50000 geological map production process, MAPCAD computer graphics system composition and function. The 1: 50000 geological map computer production process and method are mainly introduced, compared with the traditional 1: 50000 geological map production method. Finally, it is pointed out that computer graphics will eventually replace the traditional manual map production.
