Thank you Markus, I tried several methods like d.extract, or d.where | v.what map=zonpi > test and extracting cat values from the test file. Now I am wondering if it is worth (let's better say realistic given my skills) to try and write a custom module, inspired from v.digatt.
As I already had a little experience in perl and wxwidget (frontend for data capture in postgres database) I would appreciate later on to involve in writing a python add-on, but like everyone, my principal ennemy is the lack of time ! Beside data storing, treatment, analysis, I think it would be great to improve data *production* tools, and it's what I would like to contribute. Vincent.
