Equal To (Spatial Analyst)
Summary
Performs a Relational equal-to operation on two inputs on a cell-by-cell basis.
Returns 1 for cells where the first raster equals the second raster and 0 for cells where it does not.

Usage
Syntax
Parameter | Explanation | Data Type |
in_raster_or_constant1 |
The input that will be compared to for equality 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 that will be compared from for equality by the first 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 |
Return Value
Name | Explanation | Data Type |
out_raster | The output raster. The output cell values will be either integer 0 or 1; or NoData if any input cell value is NoData. | Raster |
Code Sample
This example performs a Relational equal-to operation on two GRID rasters and outputs the result as a TIFF raster.
import arcpy from arcpy import env from arcpy.sa import * env.workspace = "C:/sapyexamples/data" outEqualTo = EqualTo("degs", "negs") outEqualTo.save("C:/sapyexamples/output/outequalto.tif")
