Overview

Performs a Boolean And operation on the pixel values of two input rasters.

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

Notes

The Boolean math tools interpret the inputs as Boolean values, where nonzero values are considered true, and zero is considered false.

Two inputs are necessary for this function to execute.

The order of the inputs is irrelevant for this function.

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 being 1. The output values are always integer.

Parameters

Parameter nameDescription

Raster

The first input to use in this Boolean operation.

A constant value can be used as an input for this parameter, provided a raster is specified for the other parameter.

Raster2

The second input to use in this Boolean operation.

A constant value can be used as an input for this parameter, provided a raster is specified for the other parameter.

Extent Type

Choose which extent should be used in the output raster:

  • First Of—Use the extent of the first input raster to determine the processing extent.

  • Intersection Of—Use the extent of the overlapping pixels to determine the processing extent. This is the default.
  • Union Of—Use the extent of all the rasters to determine the processing extent.
  • Last Of—Use the extent of the last input raster to determine the processing extent.

Cellsize Type

Choose which cell size to use in the output raster. If all the input cell sizes are the same, all the options will yield the same results.

  • First Of—Use the first cell size of the input rasters.
  • Min Of—Use the smallest cell size of all the input rasters.
  • Max Of—Use the largest cell size of all the input rasters. This is the default.
  • Mean Of—Use the mean cell size of all the input rasters.
  • Last Of—Use the last cell size of the input rasters.
