要将xian80地理坐标系转换成投影坐标系：

xian1980 = """GEOGCS["GCS_Xian_1980",  DATUM["Xian_1980",    SPHEROID["Xian_1980",6378140.0,298.257]],  PRIMEM["Greenwich",0.0],  UNIT["Degree",0.0174532925199433]]"""prjreference = 'PROJCS["Xian_1980_3_Degree_GK_Zone_37",GEOGCS["GCS_Xian_1980",DATUM["D_Xian_1980",SPHEROID["Xian_1980",6378140.0,298.257]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Gauss_Kruger"],PARAMETER["False_Easting",37500000.0],PARAMETER["False_Northing",0.0],PARAMETER["Central_Meridian",111.0],PARAMETER["Scale_Factor",1.0],PARAMETER["Latitude_Of_Origin",0.0],UNIT["Meter",1.0]]'

转换后会报错：

latlong = transform.TransformPoint(x,y) File "/usr/lib/python3/dist-packages/osgeo/osr.py", line 711, in TransformPoint  return _osr.CoordinateTransformation_TransformPoint(self, *args)NotImplementedError: Wrong number or type of arguments for overloaded function 'CoordinateTransformation_TransformPoint'. Possible C/C++ prototypes are:  OSRCoordinateTransformationShadow::TransformPoint(double [3])  OSRCoordinateTransformationShadow::TransformPoint(double [3],double,double,double)**想想之前也没发现过这个问题呀，最后发现之前投影坐标系：**'PROJCS["Xian_1980_3_Degree_GK_Zone_37",GEOGCS["GCS_Xian_1980",DATUM["D_Xian_1980",SPHEROID["Xian_1980",6378140.0,298.257]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Transverse_Mercator"],PARAMETER["False_Easting",37500000.0],PARAMETER["False_Northing",0.0],PARAMETER["Central_Meridian",111.0],PARAMETER["Scale_Factor",1.0],PARAMETER["Latitude_Of_Origin",0.0],UNIT["Meter",1.0]]'**不是高斯-克吕格投影而是横轴墨卡托，我想原因可能是gdal库里只能支持高斯-克吕格投影吧。**
