Preferred Term:

map overlay

Definition:
A transparent sheet accompanying a map, on which information, coloring, or symbols are entered so that when the overlay is placed on the map the effect is identical to having entered the overlay information on the map itself. By combining several overlays it becomes a simple matter to display a variety of data combinations and stratifications which would not be possible otherwise.
