[GRASS-user] Copy a vectormap

GRASS GRASS user

Hello,

Is there any possibility to copy a vector-map with only selected columns?

E.g. I have a vectormap "Buildings" with the columns area, id, permeter,
cat, etc.
and I want to have a copy from this vectormap with only the columns id and
area

Thanks for your help

Hi gutle.

You mean you want to avoid using "g.copy + v.db.dropcol" ?

Hi Nikos

yes. i want to avoid using "g.copy + v.db.dropcol".
the problem is, I have too much unnecessery column after all Gis operations.
such as a_a_cat, a_b_cat and so on...

I see. I guess it is not possible (currently?) to avoid using "v.db.dropcol"
and/or "v.db.renamecol".
