Boolean XOr (Image Analyst)

Available with Spatial Analyst license.

Available with Image Analyst license.

Summary

Performs a Boolean eXclusive Or operation on the cell values of two input rasters.

If one input value is true (non-zero) and the other false (zero), the output is 1. If both input values are true or both are false, the output is 0.

Illustration

OutRas = BooleanXOr(InRas1, InRas2)

Usage

• The Boolean 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 Boolean evaluation to take place.

• The order of inputs is irrelevant for this tool.

• If the input values are floating point, they are converted to integer values of either 0 or 1 before the operation is performed. If the input value is a floating point 0.0, it is converted to an integer 0. If the input is any value other than 0.0, it is converted to an integer 1. For example, input float values of 0.6, 32.22 and -4.2 will all be treated as 1. The output values are always integer.

• If both inputs are single band rasters, or one of the inputs is a constant, the output will be a single band raster.

• If both inputs are multiband rasters, or one of the inputs is a constant, the output will be a multiband raster. The number of bands in each multiband input must be the same.

• The tool will perform the operation on each band from one input against the corresponding band from the other input. If one of the inputs is a multiband raster and the other input is a constant, the tool will perform the operation against the constant value for each band in the multiband input.

Syntax

BooleanXOr(in_raster_or_constant1, in_raster_or_constant2)

Parameter	Explanation	Data Type
in_raster_or_constant1	The first input to use in this Boolean operation. 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 Boolean operation. 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 cell values will be either 0 or 1.	Raster

Code sample

BooleanXOr example 1 (Python window)

This example performs a Boolean XOr operation on two Grid rasters and outputs a TIFF raster.

import arcpy
from arcpy import env
from arcpy.ia import *
env.workspace = "C:/iapyexamples/data"
outBooleanXOr = BooleanXOr("degs", "negs")
outBooleanXOr.save("C:/iapyexamples/output/outboolxor.tif")

BooleanXOr example 2 (stand-alone script)

This example performs a Boolean XOr operation on two Grid rasters.

# Name: BooleanXOr_Ex_02.py
# Description: Performs a Boolean Exclusive Or 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 = "negs"

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

# Execute BooleanXOr
outBooleanXOr = BooleanXOr(inRaster1, inRaster2)

# Save the output 
outBooleanXOr.save("C:/iapyexamples/output/outboolxor")
