[GRASS-user] Re: [GRASS-dev] Grass Python question: do not print warnings
Hi MArtin
It worked
I just have one final question:
I pretend to apply your suggestion to
proj_image = grass.read_command('g.proj', flags = 'jf', georef = src_file)
to this.
If I get a piece of text in proj_image (like the geoprojection information
of the src_file, will the stderr=nulldev eliminate the output of this
function?
Thanks

Re: [GRASS-user] Export/define region with Map Scale

Ok. So I just need to define the scale-output . Seems reasonably and easy :) 2- Is it possible to set region using this map scale definition in order to have by default this setting? not directly, but you could write a script wrapping g.region and d.info which after calibration could keep you somewhat close to your desired scale. That's probably more trouble than it's worth though. yes. It seems to.
