hello everybody,
I know that this is probably a ridiculously simple question, but I a rather
new to the syntax and have tried this for about 2 hours now. I want to
reproject decimal coordinates in epsg 4326 to 25832 and I want the output
values to have three decimal places instead of 2. I have tri

Dennis,
You either have to know the absolute path to gdal_polygonize.py or have
its location on your system path to make that work. And I also recommend
the subprocess module instead of the deprecated os.system.
import subprocess
subprocess.check_output(
['/PATH/TO/gdal_polygo
Runing a command to do a gdal_polygonize, the gdal_translate and org2org
functions work just ifne, just not poloygoize..??
os.system('gdal_polygonize tmp.4.vrt -f KML tmp.5.kml')
I get :
python: can't open file '\bin\gdal_polygonize.py';: error 2, no such
file or directory

I converted with my own gdal64 build (not sure what driver was used to
read the .jp2 file) and the file is fine, with a size very close to the
32 bit one.

Hi,
What could be the reason that Windows 64-bit gdal_translate makes many times
bigger jpeg compressed tiff files than 32-bit build? I have not made a
thorough analysis but I feel that this happens only with B/W images.
My command is simple
gdal_translate -of GTiff -co tiled=yes -co compress=jpe
