這篇文章主要介紹如何解決pythongdal投影坐標(biāo)系轉(zhuǎn)換的問(wèn)題，文中介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們一定要看完！

要將xian80地理坐標(biāo)系轉(zhuǎn)換成投影坐標(biāo)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]]'

轉(zhuǎn)換后會(huì)報(bào)錯(cuò)：

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)**想想之前也沒(méi)發(fā)現(xiàn)過(guò)這個(gè)問(wèn)題呀，最后發(fā)現(xiàn)之前投影坐標(biāo)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-克呂格投影而是橫軸墨卡托，我想原因可能是gdal庫(kù)里只能支持高斯-克呂格投影吧。**
