摘要
通过一项工程和不同参考椭球转换软件的实现过程,探讨了不同参考椭球GIS数据的转换问题。首先介绍了转换的数学模型和软件的实现过程。其次介绍了几种转换方法,并通过一个工程实例介绍了具体的操作步骤。最后对这个工程实例进行了可行性分析。
The paper deals with the conversion of CIS data of different reference ellipsoids. It has introduced the mathematics model for conversion and realization process of software, a couple of conversion methods and concrete working steps with an engineering case. Finally, a feasibility analysis has been made on the case.
