Times (3D Analyst)

Summary

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

Illustration

Times_3d (InRas1, InRas2, OutRas)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.

• 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

Dialog

Label	Explanation	Data 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

Return Value

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

Python

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

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.	Raster Dataset
