[GRASS-user] v.patch and cat values

[Tyler Smith]

Hi,

I've just patched to vector maps together, using v.patch, followed by
v.clean and v.db.addtable to add "reg_name varchar(40)". This all
worked well, so I then turned to populating reg_name using d.what.rast
-e. This also worked without problem. However, I now realize that the
table created for this new vector map has given areas from the two
different maps input to v.patch the same cat number. So when I edit
the reg_name for an area from input map 1, it also applies that
edit to an area from input map 2.

Is there a way to re-assign cat numbers to the areas in my map so that
I can give them unique names? Ideally without having to repeat the
v.patch step, as I've spent a couple hours doing d.what.rast editing!
