Research of the Coordinate Conversion between WGS84 and CGCS2000
Key Laboratory for Land Environment and Disaster Monitoring of NASMG，China University of Mining and Technology，
Abstract With CGCS2000 widely used in China, it is necessary to transform previous WGS84 coordinates into CGCS2000 coordinates. Coordinate conversion first transforms WGS84 coordinates to ITRF coordinates and then switches to CGCS2000 coordinates. This paper will use the seven-parameter method and frame conversion to achieve coordinate conversions between WGS84 and CGCS2000. It also selects an example of calculation and analysis of data.
Key words ：
