Combo Overlay

A combo overlay, combining a Rainfall Overlay with two average grid overlays (NORMAL and SOCIAL), using only the highest values in the last time frame.

The combo overlay is a grid overlay which can combine up to three 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 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.

Name	Arguments	Displays
SIN	Single	Sine function
COS	Single	Cosine function
TAN	Single	Tangent function
ASIN	Single	Arc sine function
ACOS	Single	Arc cosine function
ATAN	Single	Arc tangent function
ROUND	Single	Round function
FLOOR	Single	Floor function
CEIL	Single	Ceil function
ABS	Single	Absolute function
EXP	Single	Exponential function
LN	Single	The natural logarithm (base e) function
LOG	Single	The natural logarithm (base 10) function
SQRT	Single	The square root function
RANDOM	Single	The random function, which returns a number greater than or equal to 0.0 and less than the provided argument
ADD	Multi	Add one or more argument
MULT	Multi	Multiply one or more arguments
SUB	Multi	Subtract one or more arguments from the first argument
DIV	Multi	Divide the first argument with one or more other arguments
MIN	Multi	Returns the smallest of the provided arguments. That is, the result is the argument closest to negative infinity.
MAX	Multi	Returns the largest of the provided arguments. That is, the result is the argument closest to positive infinity.
POW	Multi	Raises the first argument to the power of the consecutive arguments. For example 2 to the power 3 to the power 4.
OR	Multi	Returns 1.0 if any argument is not equal to 0.0.
AND	Multi	Returns 1.0 if all arguments are not equal to 0.0.
GTE	Pair	Returns 1.0 if the first argument is larger than or equal to the second argument, else returns 0.0.
GT	Pair	Returns 1.0 if the first argument is larger than the second argument, else returns 0.0.
LTE	Pair	Returns 1.0 if the first argument is smaller than or equal to the second argument, else returns 0.0.
LT	Pair	Returns 1.0 if the first argument is smaller than the second argument, else returns 0.0.
NEQ	Pair	Returns 1.0 if the first argument is not equal to the second argument, else returns 0.0.
EQ	Pair	Returns 1.0 if the first argument is equal to second argument, else returns 0.0.

Timeframes

To query a specific timeframe add its number. E.g. A2 queries timeframe 2 from Input Overlay A.
To query multiple timeframes add start:end numbers. E.g. A1:5 is identical to "A1 A2 A3 A4 A5".
