[Gdal-dev] GDAL scripting with Python 2.5 (on windows)

[Aleksey Naumov]

Markus,

Thank you for your detailed help and reference to the previous discussion on
switching to the GDAL 1.6 environment (gdal16.bat). I mostly got OSGeo4W to
work for me, thanks to comment from Ivan, just have some issues with ECW and
MrSID support.

Thanks for the pointer to use "from osgeo import gdal" instead of "import
gdal". you are right, that was not my problem (the problem was, in fact,
missing gdal-python bindings package), but it is good to know, I fixed my
scripts to use the "osgeo" namespace.

I probably will not venture into setting the OSGeo4W python to be the
default on my system (have to careful with ESRI products and some other
things), but thank you for the pointers. I'll look at them for info.

Take care,

Aleksey
