Storing result from gdallocationinfo as variable in Python
You can capture standard out this way:
from subprocess import Popen, PIPE
cmd = ['gdallocationinfo', '-geoloc', '-valonly', src, lng, lat]
p = Popen(cmd, stdout=PIPE)
p.wait()
val = p.stdout.read()
I did a little more digging and found the answer to my question:
instead of using os.system, the correct syntax for storing the result in a variable is:
result = os.popen('gdallocationinfo -valonly -wgs84 %s %s' % (lyr, loc)).read()
I think you will have to use the subprocess syntax, it is explained in this post:
