Discussion on Conversion Method of Independent Coordinate System |
| |
| Abstract: | Based on the data of outcome of a municipal road control network in Huaxi District of Guiyang City,combined with the relevant theories of establishing an independent coordinate system in Guiyang City.Plane four parameter models,affine transformation model and polynomial fitting method are used to implement the conversion of the Guiyang independent coordinate system to 2000 National Geodetic Coordinate System.Finally,precision evaluation and analysis on various conversion results.The ultimate goal is to provide empirical reference for future engineering applications. |
