| 摘 要： | 由于现有的基于重合点上两组三维坐标求解空间转换参数的模型不适用于数千平方公里的整个区域,提出了一种基于投影面直接求解由三维地心坐标系到区域性坐标系的空间转换参数的方法.该方法只需利用GPS控制点上经由水准联测所得到的正常高,在确定与既有投影面最优拟合的区域性椭球面过程中,就能解得其椭球参数和空间转换参数,而且此空间转换模型并不涉及现有的平面坐标,因此在维持现有平面坐标不变的情况下也能获得应用. |

| Abstract: | For the current spatial transformation models and methods based on a pair of three-dimensional coordinates of the superposition points cannot be applied to the entire region of thousands of square kilometers,this paper presents a direct solution for the spatial transformation parameters from the three-dimensional geocentric coordinate system to the regional coordinate system based on the projection plane.Consequently,the ellipsoid parameters and the spatial transformation parameters can be appropriately sol... |
| Keywords: | projection plane three-dimension geocentric coordinate system regional coordinate system method of spatial transformation conversion on ellipsoid |
