Divide (Spatial Analyst)

Summary

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

Usage

Syntax

Divide (in_raster_or_constant1, in_raster_or_constant2)
ParameterExplanationData Type
in_raster_or_constant1

The input whose values will be divided by the second input.

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 whose values the first input are to be divided by.

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 quotient of the first input raster (dividend) divided by the second input (divisor).

Code Sample

Divide example 1 (Python window)

This example divides the values of the first input raster by the second.

import arcpy
from arcpy import env
from arcpy.sa import *
env.workspace = "C:/sapyexamples/data"
outDivide = Divide("degs", "negs")
outDivide.save("C:/sapyexamples/output/outdivide2")
Divide example 2 (stand-alone script)

This example divides the values of the first input raster by the second.

# Name: Divide_Ex_02.py
# Description: Divides the values of two rasters on a cell-by-cell basis
