摘要
南昌市现行的坐标系统难以满足城市快速发展的需要,建立新的城市独立坐标系统,解决城市扩展过程中日益严重的投影变形问题,是当前南昌市测绘基准建设的重要工作。依据《城市坐标系统建设规范》,结合国家推行2000国家大地坐标系的要求,应用地方独立坐标系建立的方法,对建立CGCS2000椭球下的南昌2000坐标系的可行性进行了系统分析。
Nanchang current coordinate system has been difficult to meet the needs of rapid urban development, the establishment of new urban independent coordinate system to solve the growing process of urban expansion projection deformation, is the current top priority of Nanchang mapping datum construction. In this paper, we applied local independent coordinate system constructing method to analyze and research the feasibility of establishinga new coordinate system under CGCS2000 ellipsoidal according to Urban coordinate system construction norms combined with the spirit of the nation implementing of CGCS2000 coordinate system.
