# Combinatorial And (Image 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.

## 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

 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

`CombinatorialAnd(in_raster_or_constant1, in_raster_or_constant2)`
 Name Explanation Data 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. Raster Layer; Constant

### Return Value

 Name Explanation Data Type out_raster The output raster.The output is always of integer type. Raster

### Code sample

CombinatorialAnd example 1 (Python window)

This example performs a Combinatorial And operation on two GRID rasters and outputs the result as a TIFF raster.

``````import arcpy
from arcpy import env
from arcpy.ia import *
env.workspace = "C:/iapyexamples/data"
outCAnd = CombinatorialAnd("degs", "cost")
outCAnd.save("C:/iapyexamples/output/outcand.tif")``````
CombinatorialAnd example 2 (stand-alone script)

This example performs a Combinatorial And operation on two GRID rasters.

``````# Name: CombinatorialAnd_Ex_02.py
# Description: Performs a Combinatorial And operation on the pixel
#              values of two input rasters
# Requirements: Image Analyst Extension

# Import system modules
import arcpy
from arcpy import env
from arcpy.ia import *

# Set environment settings
env.workspace = "C:/iapyexamples/data"

# Set local variables
inRaster1 = "degs"
inRaster2 = "cost"

# Check out the ArcGIS Image Analyst extension license
arcpy.CheckOutExtension("ImageAnalyst")

# Execute CombinatorialAnd
outCAnd = CombinatorialAnd(inRaster1, inRaster2)

# Save the output
outCAnd.save("C:/iapyexamples/output/outcand")``````
