    Grazie Giovanni. Con 'Unisci attributi per posizione' creo un nuovo
    file, in cui avro' il vecchio campo che avrei voluto
    popolare/aggiornare di A piu' quello di B di cui avrei voluto
    prendere tutti o parte i valori.<br>
    Quando dicevo farlo in piu' passaggi, intendevo proprio l'utilizzo
    di questa funzione piu' un rimaneggiamento della tabella associata
    al file che si viene a creare. O sbaglio?<br>
    <br>
    Invec e io avrei voluto fare direttamente (come facevo con Mapinfo),
    ad esempio, prendimi i punti di A in cui il comune non e'
    specificato e aggiorna il campo 'comune' con il campo 'comune' del
    layer B<br>
    <br>
    Grazie, ciao<br>

                      QGis non riesco a fare in UN SOLO passaggio due
                      cose che con il vecchio sw proprietario affrontavo
                      regolarmente: <br>
                      <br>
                      1) spezzare i poligoni di un layer A con quelli di
                      un layer B, conservando anche la parte di A che
                      non e' sovrapposta a B <br>

                      2) popolare o aggiornare, interamente o solo per
                      alcuni record, un campo del layer A prendendo
                      informazioni da elementi del layer B che sono in
                      relazione spaziale con A. <br>
                      <br>
                      In piu' passaggi lo so fare ma mi piacerebbe
                      sapere se esiste un metodo piu' diretto. Grazie <br>
