Times (Spatial Analyst)

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).

Syntax

Times (in_raster_or_constant1, in_raster_or_constant2)

Parameter	Explanation	Data 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

Name	Explanation	Data Type
out_raster	The output raster. The cell values are the product of the first input multiplied by the second.	Raster

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
# Author: ESRI

# 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
