| Abstract: | In the transformation from national reference??ellipsoid??centric coordinate to national geocentric coordinate, the lack of precise geodetic elevation of control points in reference??ellipsoid??centric coordinate makes the rectangular space coordinates of control points contain error. And this factor has an impact on final conversion accuracy. Up to late the 3D space coordinate model based on least squares has not taken into account the influence. In this paper,we discuss the method of 3D space coordinate transformation based on total least squares, besides, compare the methods of coordinate transformation based on total least squares and least squares used known data.The result shows that the accuracy of the former is better than the later. |
| Keywords: | geodetic elevation total least squares (TLS) least squares (LS) coordinate system transformation Gauss-Markov model |
