[[File:Combo_overlay_example1.jpg|thumb|250px|left|A combo overlay, combining a [[Rainfall overlay]] with two AVG grid overlays (NORMAL and SOCIAL), using only the highest values in the last time frame.]]
The combo overlay is an overlay which can combine up to three [[Grid Overlay| grid overlays]] with boolean operators and use these overlays as input arguments functions and operators. The list of available functions and operators is given below. Combo overlays can also take other combo overlays as input. Another powerful combination is the use of combo overlays with [[Average Overlay|average overlays]] (with or without an average distance).

==Operators==
In the table below are the operators displayed that are supported by the combo overlay. The term argument refers to a grid overlay configured as input, a numerical value or a global name.
