This page describes a use case for implementing a combo overlay.

Use Case Description

In an area, the locations for a clinic, a school and a sports center are known. Which area is for all three locations within a one kilometer range?

For this we would need to combine three AVG grid overlays, one for each location. then we would need to combine these three ranges in a new combo overlay, linking all three AVG overlays with a formula.

Formula

The formula for the use case, based on the operators table on the combo overlay page, would look like this:

MUL(MIN(A, B, C), 10)

Where A, B and C are the AVG grid overlays.
