[GRASSLIST:3415] Snapping thershold

GRASS GRASS user

Hi,

Is there a way to set the snapping and digitizing thershold relative to the zoom (scale) of the digitized map? I mean to change the snapping threshold with zooming in and out in v.digit.

The last time when I was digitizing I had the impression the snapping in v.digit behaved so. Is it possible it changed to an absolute value? How would I correct this?

Another question:
Where do the temporary files of GRASS 5.3 reside? Is it the .tmp directory in the location directory or there anything else?

Thanks, Miha Staut

In 5.7 (v.digit -> settings -> settings) you can select threshold either
in screen pixels or in map units.

directory in the location directory or there anything else?

Usually:
[GISDBASE]/[LOCATION_NAME]/[MAPSET]/.tmp

but sometimes it can put files in /tmp (those need to be updated to
use g.tempfile, usually contributed scripts)

You can remove any temporary files with the following command:
$GISBASE/etc/clean_temp

(e.g. before switching mapsets with 'g.gisenv set="MAPSET=foo"')
