Within the same mapset, is it possible to specify SQLITE as the database for
the output layer, whilst using a map as an input that has a PG driver?
I’ve read the manual and tried a few approaches, but I found the outputs still
get written to PG. May be I’ve missed a critical step? See

Thanks Moritz. I am getting an SQLite error when trying to run v.net.allpairs.
This is my latest workflow, incl. my checks and output messages of each step.

SET WITH PG DRIVER)
db.connect driver=pg
As context, I’m running analysis using v.net.allpairs, whereby vector
geometries are often common to more than 1 origin-destination journey path,
hence the line segments appear multiple times but with unique cat values, and
from_cat and to_cat combinations.
When exporting the output layer of
I was making progress with the r.stream.basins issue until I went to edit my
vector pour-points layer to move them over the highest flow accumulation. At
this point I got an error (that I didn't capture) that crashed the GUI,
something about being unable to find the extents of either the layer
Dear GRASS users,
I would like to announce a new addon module v.ellipse [1] to compute
the best-fitting ellipse for given vector data. The module has been
written by Tereza Fiedlerova (cc'ed) at the CTU in Prague.
Enjoy! Regards, Martin

Creating color table for output raster
Hi,
I have to calculate the percentage of given class of a raster within the
polygons given in a vector (a regular grid). Since I'm dealing with large
files and operations repeated in a chain, i should be focusing on what is
the optimal (fastest) option to do that. I could vectorize the raster
