Ivan, Thank you, this works. I must have overlooked the gdal-python bindings package in the Advanced settings on my last try.
Comparing to FWTools, I get a sense that the OSGeo4W GDAL/Python bundle is pretty complete. At least it has all the usual GDAL utility programs and python scripts. One thing I am currently missing in OSGeo4W GDAL is support for ECW and MrSID -- is it available? I've installed the gdal-ecw and gdal-mrsid packages, but it seems I am missing the DLLs. E.g. when I try "gdalinfo --formats" I get complaints: ERROR 1: Can't load requested DLL: C:\OSGeo4W\apps\gdal-16\bin\gdalplugins\gdal_ECW_JP2ECW.dll 126: The specified module could not be found. ERROR 1: Can't load requested DLL: C:\OSGeo4W\apps\gdal-16\bin\gdalplugins\gdal_MrSID.dll 126: The specified module could not be found. Have tried this with both gdal-* and gdal16-* packages. And remembered to run gdal16.bat to activate the GDAL 1.6 environment. However, can't get ECW and MrSID support. I suspect this is due to licensing issues. Do I need to install support for these formats separately?
