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",line711,inTransformPoint return_osr.CoordinateTransformation_TransformPoint(self,*args) NotImplementedError:Wrongnumberortypeofargumentsforoverloadedfunction'CoordinateTransformation_TransformPoint'. PossibleC/C++prototypesare: 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。**
