Combinatorial Or (Spatial Analyst)

Available with Spatial Analyst license.

Summary

Performs a Combinatorial Or operation on the cell values of two input rasters.

If either input value is true (non-zero), the output is a different value for each unique combination of input values. If both inputs are false (zero), the output value is 0.

Illustration

OutRas = CombinatorialOr(InRas1, InRas2)

Usage

• The Combinatorial math tools interpret the inputs as Boolean values in which nonzero values are considered true and zero is considered false.

• Two inputs are necessary for this combinatorial evaluation to take place.

• The order of inputs for this tool is only relevant for the output attribute table.

Parameters

Dialog

Label	Explanation	Data Type
Input raster or constant value 1	The first input to use in this combinatorial operation. It must be of integer type. A number can be used as an input for this parameter, provided a raster is specified for the other parameter. To specify a number for both inputs, the cell size and extent must first be set in the environment.	Raster Layer; Constant
Input raster or constant value 2	The second input to use in this combinatorial operation. It must be of integer type. A number can be used as an input for this parameter, provided a raster is specified for the other parameter. To specify a number for both inputs, the cell size and extent must first be set in the environment.	Raster Layer; Constant

Return Value

Label	Explanation	Data Type
Output raster	The output raster. The output is always of integer type.	Raster

Python

CombinatorialOr(in_raster_or_constant1, in_raster_or_constant2)

Name	Explanation	Data Type

in_raster_or_constant2	The second input to use in this combinatorial operation. It must be of integer type. A number can be used as an input for this parameter, provided a raster is specified for the other parameter. To specify a number for both inputs, the cell size and extent must first be set in the environment.	Raster Layer; Constant

Return Value
