The GRASS module v.distance will do that. If you supply the
parameters <br>
"upload=dist" and <br>
"column=<which column to upload distance into> "<br>
then in the attribute table of the "from" vector the distances to
the closest feature in the "to" vector will appear.<br>
Also the parameter "output=<line vector for connectors>"
specifies where to store the lines connecting the features between
the "from" vector and the closest feature in the "to" vector.<br>
<br>
(You might want to post questions like this to the grass-users list
instead)<br>
