摘要
我国已经正式启用了2000国家大地坐标系,本文分析了原有贵阳市城市坐标系存在的问题及贵阳市CGCS2000城市独立坐标系投影变形,着重讨论了在CGCS2000框架下建立贵阳市新一代城市独立坐标系的技术方法、难度以及解决问题的办法。
The CGCS 2000 national coordinate system has been established in China. This paper analyzes the exist- ing problems of Guiyang city coordinate system and the projection deformation of the new Guiyang city coordinate system base on CGCS 2000. Focused on the discussion of CGCS2000 within the framework of the independent coordinate system to create a new generation of guiyang city technology method ,difficulty and solution to the problem.
