Since v.db.connect says there's no table, try creating a table, then
upload values into the table using v.to.db. After you've uploaded the
values, you might need to use v.db.connect to set the connection to
the table.<br>
<br>
Or it may be that you have a table (if you're using the dbf driver, the
table will be in the dbf directory in the mapset folder), but the
connection is lost. In that case, you can just use v.db.connect to
reconnect the map to the table.<br>
<br>
If the table exists, it will be in <grass data
directory>/<location>/<mapset>/dbf/ <br>

And that's the statement I used:
v.in.ascii -n 'input=/ output= format=point fs=| skip=0 'columns=x double precision, y double precision' x=1 y=2 z=0 cat=1
Did I set the right numbers for the columns?

Chris

I don't understand about WMS and WFS a lot. All I know is that there
is a server at the environmental ministry where I can see the
hydrography layers. The only thing is that the maps address changes
every day (it's a per request service I guess) I'll give r.in.wms a
try
If, by any chance, it's a WFS server, is there a download tool for it?
Cheers
Daniel

<pre wrap="">I'm sorry to disappoint You, but WMS deals with raster and not with
vectors. Vectors You can get with WFS or similar service. If You by
word "vectors" mean roads, rivers etc. displayed as raster in WMS
service, then You should:
1) Download data as rasters (r.in.wms);
2) Extract objects of interest (r.mapcalc);
3) Run r.thin to get thin lines;
4) Convert result to vectors with r.to.vect.
Still You can create buffers and other analysis on raster data.
