[gdal-dev] help printing the standard out from gdal_grid in python

[Nicolas Cadieux]

Hi,

I am not an experienced programmer.  I am calling gdal_grid from a 
python script.  I am using p.imap_ unordered to multiprocess the 
script.  The idea is the following:

--------------------

def gdal_Grid(fileList):
     gdal_Grid_Cmd = 'gdal_grid -l ....'
     shell = subprocess.Popen(r'c:\OSGeo4W64\OSGeo4W.bat', 
stdin=subprocess.PIPE)
     shell.communicate(gdal_Grid_Cmd)
     return  'done'

-------------------------

lst = [c:\temp.csv....]

if __name__ == '__main__':
     p = Pool(2)
     for x in p.imap_unordered(gdal_Grid,lst):
         print x


The Question:
I would like to print the output (standard out???) from gdal_grid. I 
can't figure how to use stdout=subprocess.PIPE. Can you help me?
Thanks
Nicolas
