When we have a polygon exposure layer, we currently calculate impact based on the centroid of the polygon. We need to add an aditional approach to this that looks at considering the relative area that is affected vs. the relative area that is unaffected. This could then be used to determine the relative proportion of people or a building that is impacted.

Particularly likely for population datasets that are often defined by an administrative boundary.
