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
Usage
The Combinatorial math tools interpret the inputs as Boolean values, where nonzero values are considered true, and zero values are 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.
See Analysis environments and Spatial Analyst for additional details on the geoprocessing environments that apply to this tool.
Syntax
CombinatorialOr(in_raster_or_constant1, in_raster_or_constant2)
| Parameter | Explanation | Data Type |
in_raster_or_constant1 | The first input to use in this combinatorial operation. It must be of positive integer type. A number can be used as an input for this parameter, provided a raster is specified for the other parameter. To be able 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 positive integer type. A number can be used as an input for this parameter, provided a raster is specified for the other parameter. To be able to specify a number for both inputs, the cell size and extent must first be set in the environment. | Raster Layer; Constant |
Return Value
| Name | Explanation | Data Type |
| out_raster | The output raster. The output is always of integer type. | Raster |
Code sample
CombinatorialOr example 1 (Python window)
This example performs a Combinatorial Or operation on two GRID rasters and outputs the result as an IMG raster.
import arcpy
from arcpy import env
from arcpy.sa import *
env.workspace = "C:/sapyexamples/data"
outCOr = CombinatorialOr("degs", "cost")
outCOr.save("C:/sapyexamples/output/outcor.img")
CombinatorialOr example 2 (stand-alone script)
This example performs a Combinatorial Or operation on two GRID rasters.
# Name: CombinatorialOr_Ex_02.py
# Description: Performs a Combinatorial Or operation on the cell
