I have created a batch file in Python 3.6.3 to clip a raster image using gdalwrap (I use some coordinates for clipping). Running the batch file in the command line gives error 'gdalwarp' is not recognized as an internal or external command,operable program or batch file. I tried https://stackoverflow.com/questions/31174320/gdal-merge-py-not-working-after-gdal-and-it-python-bindings-have-been-installed, but python is not recognized in this case. Any hint highly appreciated.
