1.大地坐标转经纬度坐标：以WGS84为例：
XYZ转BLH:
ProjCoordinate projCoordinateXYZConvertBLH = new ProjCoordinate(X, Y, Z);
GeocentricConverter geocentricConverter = new GeocentricConverter(WGS84);
geocentricConverter.convertGeocentricToGeodetic(projCoordinateXYZConvertBLH);
double b = projCoordinateXYZConvertBLH.x, l = projCoordinateXYZConvertBLH.y,h=projCoordinateXYZConvertBLH.z;
//将弧度转经纬度
System.out.println(Math.toDegrees(b), Math.toDegrees(l), h);
2.经纬度坐标转大地坐标：以WGS84为例：
BLH转XYZ：
ProjCoordinate projCoordinateBLHtoXYZ = new ProjCoordinate(b, l, h);
GeocentricConverter geocentricConverterBLHtoXYZ = new GeocentricConverter(WGS84);
geocentricConverterBLHtoXYZ.convertGeodeticToGeocentric(projCoordinateBLHtoXYZ);
double x = projCoordinateXYZConvertBLH.x, y = projCoordinateXYZConvertBLH.y,z=projCoordinateXYZConvertBLH.z;
System.out.println(x,y,z)
