Hi all,<br>
<br>
after the reprojection in another mapset I used v.line.center, all<br>
ok. But, I obtain a new layer without database. The input layer have<br>
database.<br>

<br></div>
v.line.center does not copy the input vector's table to output vector.<div class="Ih2E3d"><br>

v.db.connect -p glines1 Vector map <glines1> is connected by: layer<br>
<2> table <glines1> in database </scratch/manuel/GISDATA//admprojected/manuel/dbf/> through driver<br>
<dbf> with key <cat><br>

I have read that the result layer (pts1) contains the category<br>
numbers of the input vector line layer.<br>
<br>
Is there a solution?<br>
</blockquote>
<br></div>
Yes. As the category numbers are the same, you can:<br>
<br>
# given that the name of the v.line.center's input vector is "lines" and<br>
# the output is "points":<br>
<br>
# copy the input table:<br>
db.copy from_table=lines to_table=points<br>
<br>
# connect the table "points" to vector map "points":<br>
v.db.connect points table=points<br>
<br>
Now query (d.what.vect, v.db.select) to check if everything's OK.<br>
<br>
Mind that I assume plenty of defaults in the example above - verify your<br>
layer number, key column name etc. Refer to to commands's manuals.<br>
