浅谈独立坐标系的建立

Discussed on Building of Independent Coordinate System

结合工程测量实际,介绍了建立地方独立坐标系的因素,通过地方坐标系的建立,阐述了利用GPS技术建立独立坐标系的椭球变换方法。根据工程测量中长度投影变形的影响等因素和大型工程测量的要求,应建立地方独立坐标系。介绍了独立坐标系建立的一般方法。

Combining fact of engineering surveying, the authors thought that country shuld build local independent coordinate system according to impact of length projection distortion and demand of large-scale engineering surveying. In this paper, the authors introduced general approach of building independent coordinate system and elaborated on method of ellipsoid transformation in building independent coordinate system by using GPS technology.
