"Multidirectional, oblique-weighted, shaded-relief". ArcGis has this
script:

Greetings
I have a script where I need to define a region based on 2 rasters output[0]

grass.run_command("g.region", rast = output[2] output[3], res= t_srx)
But This is not correct. my question is how can I have both rasters without

Hello. I need to learn how to use GIS and I have chosen to do it with GRASS.
My plan is to learn GIS/GRASS essentials during the next 12 months and start

available documentation and also started playing with the sample data
