Usage

  • The order of inputs is irrelevant for this tool.

  • If both inputs are integer, the output will be an integer raster; otherwise, it will be a floating-point raster.

  • 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, the tool will perform the operation on each band from one input, and the output will be a multiband raster. The number of bands in each multiband input must be the same.

  • If one of the inputs is a multiband raster and the other input is a constant, the tool will perform the operation using the constant value for each band in the multiband input, and the output will be a multiband raster.

  • If both inputs are multidimensional raster data with the same number of variables, the tool will perform the operation for all slices with the same dimension value. The output will be a multidimensional raster in CRF format. The variables in the inputs must have at least one common dimension and one common dimensional value for this tool to process; otherwise, an error will occur.

    If both inputs have one variable but different names, uncheck the Match Multidimensional Variable geoprocessing environment (set arcpy.env.matchMultidimensionalVariable = False in Python) before running the tool.

    If one of the inputs is a multidimensional raster and the other input is a constant, the tool will perform the operation for all slices for all variables using the constant value, and the output will be a multidimensional raster.

Parameters

LabelExplanationData Type
Input raster or constant value 1

The input containing the values to be multiplied.

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
Input raster or constant value 2

The input containing the values by which the first input will be multiplied.

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
Output raster

The output raster.

The cell values are the product of the first input multiplied by the second.

Raster Dataset

arcpy.ddd.Times(in_raster_or_constant1, in_raster_or_constant2, out_raster)
NameExplanationData Type
in_raster_or_constant1

The input containing the values to be multiplied.

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 input containing the values by which the first input will be multiplied.

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
out_raster

The output raster.

The cell values are the product of the first input multiplied by the second.

Code sample

Times example 1 (Python window)

This example multiplies the values of an input elevation raster by a constant value to convert the elevation values from feet to meters.

import arcpy
from arcpy import env
env.workspace = "C:/data"
arcpy.Times_3d("elevation", 0.3048, "C:/output/outtimes")
Times example 2 (stand-alone script)

This example multiplies the values of an input elevation raster by a constant value to convert the elevation values from feet to meters.
