Times (Spatial Analyst)

Summary

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

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, or one of the inputs is a constant, the output will be a multiband raster. The number of bands in each multiband input must be the same.

• The tool will perform the operation on each band from one input against the corresponding band from the other input. If one of the inputs is a multiband raster and the other input is a constant, the tool will perform the operation against the constant value for each band in the multiband input.

• 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)`
 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 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

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

# 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

# Execute Times
outTimes = Times(inRaster, inConstant)

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