Combinatorial And (Spatial Analyst)

Available with Spatial Analyst license.

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 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.

• See Analysis environments and Spatial Analyst for additional details on the geoprocessing environments that apply to this tool.

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

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.sa import *
env.workspace = "C:/sapyexamples/data"
outCAnd = CombinatorialAnd("degs", "cost")
outCAnd.save("C:/sapyexamples/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 cell
#              values of two input rasters
# Requirements: Spatial Analyst Extension

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

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

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

# Execute CombinatorialAnd
outCAnd = CombinatorialAnd(inRaster1, inRaster2)

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