Greetings

I would like to know how can I retrieve the list of available values in a Raster map in a Python Script?
Thanks

In order to get a list, here is just one approach:
vals = os.popen(“r.stats –Nn your_map”).readlines()

Hi,

In order to get a list, here is just one approach:
vals = os.popen(“r.stats –Nn your_map”).readlines()

use GRASS Scripting Library [1]

grass.read_command('r.stats', flags='Nn',input = 'map').splitlines()
