I doubt it. I think he's looking for the plan view area of each region, i.e., each
colored band between defined limits.

I remember the good old days, pre-Excel. We had a fancy device called a planimeter
to measure these areas. A less elaborate procedure consisted of cutting out the
areas and weighing them, dividing by the total weight, and multiplying by the total
area.
