Log10 (Spatial Analyst)

Available with Spatial Analyst license.

Summary

Calculates the base 10 logarithm of cells in a raster.

OutRas = Log10(InRas1)

Usage

  • The input can be of integer or float type.

    You can review some results for floating-point input values in the examples of output values from the Logarithmic tools.

  • Input values that are 0 or negative will be NoData in the output raster.

  • The output raster from this tool is always floating-point type, regardless of the input value type.

  • If the input is a multiband raster, the output will be a multiband raster. The tool will perform the operation on each band in the input.

  • If the input is multidimensional raster data, all slices from all variables will be processed. The output will be a multidimensional raster in CRF format.

Parameters

LabelExplanationData Type
Input raster or constant value

Input values for which to find the base 10 logarithm.

To use a number as an input for this parameter, the cell size and extent must first be set in the environment.

Raster Layer; Constant

Return Value

LabelExplanationData Type
Output raster

The output raster.

The cell values are the base 10 logarithm of the input values.

Raster

Log10(in_raster_or_constant)
NameExplanationData Type

Input values for which to find the base 10 logarithm.

To use a number as an input for this parameter, the cell size and extent must first be set in the environment.

Raster Layer; Constant

Return Value

NameExplanationData Type
