摘　　要：本文从工作实际出发阐述了工程设计中利用矢量化老图纸和新测电子图拼接成图时出现的一些问题,如新老电子图高程基准不一致、坐标系不统一的问题,并阐述了如何利用南方CASS成图软件解决这些问题,将坐标系、高程基准统一,将新老电子图拼接成统一整体。This paper describes some problems in the splicing the vectorization old map and the new measurement electronic map into a unified one in engineering design from the work reality,For example, height datum inconsistencies, the coordinate system is not unified. This paper explains how to use the South eass mapping software to solve these problems, the coordinate system, vertical datum unification, the new and old electronic map together into a unified whole.
