Last minute question while preparing a class for tomorrow: anyone have a good idea on how fix the scale at which one digitizes with v.digit (i.e. not the new wxgui digitizer) ? Currently, the best idea I have found is to use the wxgui to display a map at a fixed scale, save the display to a named region and set the computational region to the current display. Then start v.digit and only use panning. If I ever have to zoom, I then use the named region I saved to get back to my scale.

the value there is not accurate and should not be trusted for
anything other than a rough estimate. see the tooltip message.
it depends on your monitor size and screen resolution.
on the printed page (ps.map) it means something.
this is why I don't like keeping that scale feature in the
wxgui- we print a number and people trust that it means something.
see the wish in the bug tracker for a screen calibration tool
similar to what inkscape,gimp uses to deal with this problem.
my best advice is try to keep a d.barscale on screen, and work
from that.
