Ciao Elena,
grazie delle informazioni per=F2 non sono sicura di aver capito bene come=
fare ad importare dei dati dal formato Arc-info ungenerate al formato di=
Premetto che non conosco il formato di arc-info.

Tra le risposte alla mia mail, ho ricevuto la seguente:

"....The truth is that the data supplier need only ungenerate once, assuming
that he/she dumps all Arc attributes at that time.

The rub is that GRASS only allows one attribute at a time to be
associated with the polygons.  Therefore, *on the user's side*, at the
time the file is imported with, the user will have to pick an
attribute, or, alternatively, create one GRASS layer per attribute."

questo significa che se devo importare una carta delle isoipse devo
importare uno per uno tutti gli insiemi delle isoipse di una data quota?
Ho capito bene?=20

Chiariscimi le idee per favore!

Grazie e ciao,
