Combinatorial And (Spatial Analyst)
Summary
Performs a Combinatorial And operation on the cell values of two input rasters.
If both input values are true (non-zero), the output is a different value for each unique combination of input values. If one or both inputs are false (zero), the output value is 0.
Illustration
 |
OutRas = CombinatorialAnd(InRas1, InRas2) |
Usage
The Combinatorial math tools interpret the inputs as Boolean values, where non-zero 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.
Syntax
| 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. | Raster |
Code Sample
This example performs a Combinatorial And operation on two GRID rasters and outputs the result as a TIFF raster.

from arcpy import env
from arcpy.sa import *
env.workspace = "C:/sapyexamples/data"
outCAnd = CombinatorialAnd("degs", "cost")
outCAnd.save("C:/sapyexamples/output/outcand.tif")
