Combinatorial And (Spatial Analyst)

License Level:BasicStandardAdvanced

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

Syntax

CombinatorialAnd (in_raster_or_constant1, in_raster_or_constant2)
ParameterExplanationData 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.

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"

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

# Execute CombinatorialAnd
outCAnd = CombinatorialAnd(inRaster1, inRaster2)

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