| Abstract: | We focus on the coordinate transformation method in Xining CORS.The observation data of CORS station in Xining City is analyzed using Gamit/Globk software.Then,7-parameter method is implemented in the result of above-mentioned processing,which effectively reduces the projection deformation owing to the high altitude and high difference in elevation between control points.High-precision conversion from 3-D spatial datum to 2-D plane datum is realized using 7-parameter and 4-parameter in Xining City. |
