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",0.0174532925199433]],PROJECTION["Gauss_Kruger"],ParaMETER["False_Easting",37500000.0],ParaMETER["False_northing",ParaMETER["Central_Meridian",111.0],ParaMETER["Scale_Factor",1.0],ParaMETER["Latitude_Of_Origin",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)

**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",PROJECTION["Transverse_Mercator"],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。**

以上这篇解决python gdal投影坐标系转换的问题就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持我们。
