IT'>Abbiamo usato "Opzioni di snapping e digitalizzazione" -
"Evita intersezioni" (per rappresentare l'uso dei terreni). QGIS 2.12
disegna il nuovo poligono, però sovrapposto (parzialmente) a quello vicino. Il problema
è che (nella mancanza del messaggio) l'errore si osserva soltanto quando
è impostata una trasparenza dello strato. I miei studenti avevano
l'impressione che avessero lavorato correttamente.</span></div>
