机助大比例尺地形图绘图编码设计原理

本文介绍了地形图绘图编码的原理。这些编码能够正确地表示地形的属性特征、绘图、数据采集方式、测站间的联接方式及同类地物的区分等信息。

The principle of data codes design is introduced in this paper. These codes can indicate the information referring to terrain features, map drawing data collecting data connecting between stations and data sectioning among the same kinds of terrain features.
