How can I set the Grass Region in Python without already having a map in the Mapset? Basically I am looking for the equivalent to this window

enter image description here

Currently I am only able to extent an existing region, which leads in my case to very big regions.


How about this:

import grass.script as grass

grass.run_command('g.region', n=10, s=9, e=35, w=33, ewres=0.1, nsres=0.2, verbose=True, flags='p')
    projection: 3 (Latitude-Longitude)
    zone:       0
    datum:      wgs84
    ellipsoid:  wgs84
    north:      10N
    south:      9N
    west:       33E
    east:       35E
    nsres:      0:12
    ewres:      0:06
    rows:       5
    cols:       20
    cells:      100
  • g.region requires in my Grass (6.4.3) a parameter <map> (Raster map to change). What version are you on? What am I doing wrong? In the documentation I don't see this parameter either. – ustroetz Nov 14 '13 at 18:13
  • No, g.region works on the overall "computational region", and is not specific to one map. That's the same for all version. THere is a different command, r.region which changes the extent and resolution of a single raster. Is that what you meant? – Micha Nov 16 '13 at 11:43
