Power function

Available with Image Analyst license.

Available with Spatial Analyst license.

Overview

Raises the pixel values in a raster to the power of the values found in another raster.

Power illustration
(InRas1)2

Notes

The output raster is always a floating-point type, regardless of the input value type.

Parameters

Parameter nameDescription

Raster

The input values to be raised to the power defined by Raster2.

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

Raster2

The input that determines the power to which the values of Raster will be raised.

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.
