基于AutoCAD的地形图中高程注记的自动移位

Automatic Displacement of Topographic Elevation Note Based on AutoCAD

在基于AutoCAD的地形图中,在展绘高程点时,高程注记总是展绘在相对该高程点的固定位置,这样难免会出现高程注记遮盖其他地物的情况,通常的做法是在编辑地形图时对遮盖其他地物的高程注记进行手工移位。本文提出可以利用计算机编程实现高程注记的自动移位,从而可极大地提高地形图编辑的工作效率和图面质量。

In the AutoCAD topographic maps,the situation other land features are covered by elevation note has turned up inevitably because of elevation note always plotting at a regular position relative to the elevation points. The usual practice will shift the elevation note that has been covering other land features manually in map editing. This paper expounds elevation note can be automatic shifted by using of computer programming, that will improve work efficiency and graph quality greatly in map editing.
