要將xian80地理坐標系轉換成投影坐標系：

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]]' |
轉換后會報錯：

以上這篇解決python gdal投影坐標系轉換的問題就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支持服務器之家。
