摘　　要：首先介绍了不同的大地坐标系统及其之间的转换,然后针对具体的试验区域给出了转换方法,并开发了坐标转换辅助程序,实现了3D产品在地方独立坐标系和国家大地坐标系之间的转换,成果满足要求。通过本项目研发了软件、沉淀了技术、积累了经验,取得了良好的效果。This paper introduces different geodetic coordinate systems and the transformation of them firstly, then puts forward the transformation approach of the experimental area. At the same time, auxiliary coordinate transformation program is developed. The transformation of 3D products between local independent coordinate system and national geodetic coordinate system is realized, and the results meet requirement. Through this project, software is developed, technology is mastered, experience is accumulated and good effects are achieved.
