just tried with:
grass.run_command('v.clean', input = v_basins,
output = v_basin,
type = 'area',
tool = 'rmarea',
thresh = 1, # I also tried 10
overwrite = True)
Maybe I do something wrong, but this way I can't get rid of small polygons,
and, in addiction, I need to set the threshold parameter, which I'm not
sure to be suitable for all cases...
where am I wrong?
Thanks,
madi
