I have found the following to work for windows:

• Run python to check if your python is 32 or 64 bit.
• Install corresponding OSGeo4W (32 or 64 bit) into C:\OSGeo4W or C:\OSGeo4W64:
  • Note: Select Express Web-GIS Install and click next.
  • In the ‘Select Packages’ list, ensure that GDAL is selected; MapServer and Apache are also enabled by default, may be unchecked safely.

• Make sure the following is included in your settings.py:

  import os
  if os.name == 'nt':
      import platform
      OSGEO4W = r"C:\OSGeo4W"
      if '64' in platform.architecture()[0]:
          OSGEO4W += "64"
      assert os.path.isdir(OSGEO4W), "Directory does not exist: " + OSGEO4W
      os.environ['OSGEO4W_ROOT'] = OSGEO4W
      os.environ['GDAL_DATA'] = OSGEO4W + r"\share\gdal"
      os.environ['PROJ_LIB'] = OSGEO4W + r"\share\proj"
      os.environ['PATH'] = OSGEO4W + r"\bin;" + os.environ['PATH']
  

• Run python manage.py check to verify geodjango is working correctly.
