摘要
以贵阳市花溪区某市政道路控制网成果为数据支撑,结合贵阳市独立坐标系建立的相关理论,采用平面四参数模型、仿射变换模型、多项式拟合法实现了贵阳市独立坐标系向2000国家大地坐标系的转换,并对各种转换成果进行精度评价与分析,可为以后的工程应用提供一些参考。
Based on the data of outcome of a municipal road control network in Huaxi District of Guiyang City,combined with the relevant theories of establishing an independent coordinate system in Guiyang City. Plane four parameter models,affine transformation model and polynomial fitting method are used to implement the conversion of the Guiyang independent coordinate system to 2000 National Geodetic Coordinate System. Finally,precision evaluation and analysis on various conversion results. The ultimate goal is to provide empirical reference for future engineering applications.
