I've managed to import some vector data OK - drawing the lines everything
seem fine.
Next I wanted to add the labels to them - to do this I have created a
file with each line in the format "L 999999 999999 cat" as discussed in
the programmers guide. Place that file (with the same name as the vector)
in the 'dig_att' directory and then run 'v.support' - I then get a number
of lines of the form 'WARNING: line xx label ... matched another label
....' - thing is I've looked at the two lines and can't see how they
match - the
coordinates look different and the label is just a unique identifierCan anyone cast any light on what is going on.
Thanks,

Steve,
I usually do the same operation with no warning message. I write a file
with attributes in dig_att using a couple of coordinates belonging to the
line to wich the attribute is to be assigned. As the attribute is
assigned to the closest line (as defined by the couple of coordinates), this
insures the correct coupling line-attribute.
The operation is faster if you edit the original file (you could have it
in arc) deleting all the coordinates except the one you want to use to
assigne the attribute.
Hoping this can help you.
