[GRASS-user] [snap pour point for r.water.outlet]

[Ang Sherpa]

Thanks Helmut,
Actually when I tried to extract only the x and y with following code it
throws an error "KeyError: 'x'"

s =
gscript.parse_command(gscript.parse_command('v.report',map='snap_test',option='coor',units='meters')
print s['x']

*Best,*
