python3安装FileGDB读写驱动

python3安装FileGDB读写驱动

环境

  • 系统:win10x64
  • python:3.6.5x64

安装步骤

  1. 安装gdal: GDAL‑2.4.1‑cp36‑cp36m‑win_amd64.whl

    pip install GDAL-2.4.1-cp36-cp36m-win_amd64.whl
    
  2. 安装FileGDBAPI.dll:下载地址

    拷贝FileGDBAPI.dll至C:\Program Files\Python36\Lib\site-packages\osgeo目录,安装目录与python安装目录一致

    注意: GDAL 3.x 版本还需要把gdalplugins\disabled中的ogr_FileGDB.dll移动到gdalplugins目录

  3. 测试,已成功加载FileGDB:

    C:\WINDOWS\system32>ogrinfo --formats|findstr "GDB"
      FileGDB -vector- (rw+): ESRI FileGDB
      OpenFileGDB -vector- (rov): ESRI FileGDB
    
  4. ipython测试,可以看到gdb_driver为空,目前为止还是不能使用(GDAL 3.x 版本不需要此步骤)

    >ipython

    In [1]: from osgeo import ogr
    
    In [2]: gdb_driver=ogr.GetDriverByName("FileGDB")
    
    In [3]: gdb_driver
    
    In [4]:
    
  5. 修改osgeo/__init__.py文件:注释15行,取消注释17行(GDAL 3.x 版本不需要此步骤)

    # __init__ for osgeo package.
    
    # unofficial Windows binaries: set GDAL environment variables if necessary
    import os
    
    try:
        _here = os.path.dirname(__file__)
        if _here not in os.environ['PATH']:
            os.environ['PATH'] = _here + ';' + os.environ['PATH']
        if 'GDAL_DATA' not in os.environ:
            os.environ['GDAL_DATA'] = os.path.join(_here, 'data', 'gdal')
        if 'PROJ_LIB' not in os.environ:
            os.environ['PROJ_LIB'] = os.path.join(_here, 'data', 'proj')
        if 'GDAL_DRIVER_PATH' not in os.environ:
            #pass
            # uncomment the next line to enable plugins
            os.environ['GDAL_DRIVER_PATH'] = os.path.join(_here, 'gdalplugins')
    except Exception:
        pass
    
    del os
    
  6. 再次测试,成功!
