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.

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

LabelExplanationData 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

LabelExplanationData Type
Output raster

The output raster.

The output is always of integer type.

Raster

CombinatorialOr(in_raster_or_constant1, in_raster_or_constant2)
NameExplanationData Type
in_raster_or_constant1

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
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.
