Ok so as you can see to my question I'm a total newb at python. I'm building a python script and basically I want it to execute this line
/Library/Frameworks/GDAL.framework/Programs/ogr2ogr -f "GeoJSON" output.json input.shp
How do I get python to execute this as if I was typing it in my terminal?
Thanks
import os
os.system('/Library/Frameworks/GDAL.framework/Programs/ogr2ogr -f "GeoJSON" output.json input.shp')
More recently, it is recommended to use the subprocess package:
subprocess.call(['/Library/Frameworks/GDAL.framework/Programs/ogr2ogr', '-f',
'"GeoJSON"', 'output.json', 'input.shp'])
os.system waits for it to finish. If you want to fork the process, use subprocess.Popen.
I cannot comment, but would like to add to the above answer:
The subprocess package allows for a return handle by which you can determine if the command was executed successfully. This may be important later in your script:
import subprocess
COMMAND = '/Library/Frameworks/GDAL.framework/Programs/ogr2ogr -f "GeoJSON" output.json input.shp'
return_code = subprocess.call(COMMAND, shell=True)
