Hi,
I've just spent an hour fighting with setting the region in GRASS 7.
Finally I discovered that the display region and computational region
are now independent. Is there a way to have the computational region
automatically set to the display region, or do we now have to explicitly
link them each time one or the other changes?
This has to be done explicitely, except for the fact that you can ask
for the display to always use the computational region's resolution
('Display resolution' in the drop-down menu of the Map Display).
And there is the 'Show comp. extent' that Nikos already mentioned.
If there's no way to link
them automatically, is there a way to 'set computational region extent
from display' from the command line?
Not that I know of. AFAIK, currently the CLI does not have access to the
information about the display extent in the Map Display.
Hi Tyler,
I don't think something has been changed. Computational region (extent +
resolution) was always a GRASS core concept. And the "display" region
(using your "term") was always different, meaning, zoom in/out and
pan-ing maps in a display never altered the actual region extent and
resolution.
In the d.mon world this is exactly how things worked: zooming and
panning changed the region. The fact that display and region became
independent was a little revolution in GRASS history ;-)
