What is the relationship with the original topic of this thread ?
I'm not sure how you could run "gdal_polygonize" as such as there's no
gdal_polygonize.bat provided by default, so I imagine you created your own.
Did you remember of running "setfw.bat" before to set up appropriate
environment variables ? When doing that, I'm able to do "python
But anyway, this is of no use, since gdal_polygonize.py will require the new
generation GDAL python bindings, but (for historical reasons) FWTools comes
with old-generation GDAL python bindings that do not have the newer mappings,
like the one needed for gdal_polygonize.py
Perhaps you should try osgeo4w.
