Hi,<br><br>Apologies for delay in responding.<br><br>It doesn't matter whether I choose the cat column or another attribute column, the same issue occurs.<br><br>l haven't had a chance to test using the NC data however before raising the issue I did test using spearfish and the "fields" and "archsites" maps - this worked, but there are only 25 records.<br>
<br>What I did discover when aborting the v.distance command <u>and </u>closing winGrass is it finally wrote the data to the dbf file. It seems the command had to be aborted and winGrass shutdown, then the data was written out - I hope this gives someone a lead on the issue. <br>

hi,<br>
<div class="im"><br>
>v.distance from=txtloc@PERMANENT to=RA@PERMANENT to_type=line,area<br>
upload=cat column=cat to_column=RA_CODE<br>
<br>
</div>try to choose another column than "cat",<br>
<br>
I've tested with the nc-sample-dataset by<br>
WinGRASS-6.4.SVN-r47802-1-Setup.exe:<br>
<br>
g.copy vect=bridges@PERMANENT,mybrigdes<br>
g.copy vect=lakes@PERMANENT,mylakes<br>
v.db.addcol map=mybridges@g7 columns="areacat INT"<br>
<br>
v.distance --overwrite --verbose from=mybridges@g7 to=mylakes@g7<br>
to_type=area upload=cat column=areacat<br>
