Summary

Multiplies the values of two rasters on a cell-by-cell basis.

Illustration

OutRas = Times (InRas1, InRas2)

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.

  • In Map Algebra, the equivalent operator symbol for this tool is "*" (link).

  • See Analysis environments and Spatial Analyst for additional details on the geoprocessing environments that apply to this tool.

Syntax

Times(in_raster_or_constant1, in_raster_or_constant2)
ParameterExplanationData 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 be able 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 be able to specify a number for both inputs, the cell size and extent must first be set in the environment.

Raster Layer; Constant

Return Value

NameExplanationData Type
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
from arcpy.sa import *
env.workspace = "C:/sapyexamples/data"
outTimes = Times("elevation", "0.3048")
outTimes.save("C:/sapyexamples/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.

# Name: Times_Ex_02.py
# Description: Multiplies the values of two rasters on a cell-by-cell basis.
# Requirements: Spatial Analyst Extension

# Import system modules
import arcpy
from arcpy import env
from arcpy.sa import *

# Set environment settings
env.workspace = "C:/sapyexamples/data"

# Set local variables
inRaster = "elevation"
inConstant = 0.3048

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

# Execute Times
outTimes = Times(inRaster, inConstant)

# Save the output 
outTimes.save("C:/sapyexamples/output/timesout")
