I don't know if the "shift" word means "move" or "change".
Non so se la parola "shift" significhi "spostamento" o "modifica".
"Shift" seems to mean "move" (transfer) here, as in "moving a part of the map to another area" but I don't know why you would ever want to do this...
Furthermore, the text wasn't written by a native speaker of English, so this complicates my understanding of it. If there were more context here (e.g. why would you want to "shift" a part of the map?), it might be easier to understand...
