解决python gdal投影坐标系转换的问题
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。**
