【摘要】 以贵阳市某市政道路控制网成果为例,分别采用直接参数法、相似变换法和多项式逼近法将贵阳市城市独立坐标转换成北京54坐标。分析几种常见平面坐标转换模型的优点及不足,得出工程应用中独立坐标系转换成国家坐标系的一些有益经验。更多还原

【Abstract】 Taking a control net of urban road in Guiyang for example, this paper transformed the Guiyang City Independent Coordinates System into Beijing 54 Coordinate System by three different means of plane transformation(direct parameter transformation, similar transformation and approximation by polynomial transformation). Comparing with the result of control net, the paper analyzed the advantages and disadvantages three different means of plane transformation, and summarized some experience of coordinate transformation between city independent coordinates system and national coordinate system.更多还原
