为实现WGS84和CGCS2000坐标系之间的转换,首先通过七参数法将WGS84坐标转换到ITRF坐标,然后再通过框架转换法转换到CGCS2000坐标,并进行实例计算和分析。
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.
