Hi Markus,
You are also completely right! Some of data I exported (elevation, slope,
aspect) did not have NULL cells. And in the other data that have NULLs, I
used r.null to ensure that the NULL value was -. With that I simply
transformed the NULL cells to the value -, wich are exported

How do you specify the name of a table in the GRASS sqlite.db that is
not linked to vector objects?
Probably the manual

You could redirect it to a file (of course a "file=" parameter would
be more elegant):
# test case, NC dataset
v.extract
Hi Pedro,
I created a test case with the North Carolina sample dataset (by
zooming in the GUI to the elevation map border and setting that as
computational region):
# GRASS 7.2.2svn (nc_spm_08_grass7):~ >
# set computational region around east elevation map border
g.region n=216820 s=216770
Hi Jeshua,
You're completely right! I'd tried it, but it gaves me an error, and I did
not read it correctly, but it clearly it said that it was not possible to
assign that nodata value, because of the selected datatype!
Thank you very much for the hint! And sorry for the noise!
Best regards,

you can either operate from an sqlite3 session, or use the grass builtin
command db.execute. In

Hi Vincent,
Thanks for the verifying; I was afraid of that.

Hello Jeshua,
to my knowledge, no way to alter a column in sqlite3 :
https://www.sqlite.org/lang_altertable.html
.width only affects the output width of columns within sqlite3 prompt.
I would suggest you to simply add a new column (with the right width),
then copy the content of the previous to
13 matches
