| Abstract: | It discusses the method of coordinate transformation between local coordinate and CGCS2000,based on the transformation models of two-dimensional four parameters and three-dimensional seven parameters,aiming to achieve the conversion from local coordinate to CGCS2000 with MATLAB for platform.At the same time it analyzes the applicability and the principle of both conversion models.The conversion precise reaches to the centimetre that accords with actual project. |
