说明：  由于不同的坐标系坐标用于不同的场合,需要通过坐标转换将所得的WGS284 坐标转换到不同的坐标系统中去,从而满足不同领域的需要
( Coordinate the different coordinate systems used in different situations, needs to be obtained WGS284 coordinate transformation to a different coordinate transformation to the coordinate system to meet the needs of different areas)
