摘　　要：Visual C++的八种坐标映射模式还不能满足测绘坐标系矢量图形系统的直接显示,需要进行相应的变换。对此在分析其坐标系和映射模式基础上,以图形为中介探讨了实现原理,得出映射旋转和映射交换两种详细实现方案。并给出了两种方案的核心实现代码。实践证明该方法理解简单,易于实现,对图形开发初学者有相当参考价值,是种简洁实用的实现方案。Eight coordinate mapping modes in Visual C ＋ ＋ can not satisfy the direct indication of the Surveying and mapping coordinate vector graphics system, and there is a need for corresponding transformation. The paper starts with analyzing the coordinate system and mapping mode. The purpose of this is to analyze the realization principle by utilizing figure, and then achieve two realization scheme of revolve and exchanges, and put forward its core program. The scheme is ease to learn. It is a banausic scheme for those who begin to study the graphics exploitation.
