Plus (3D Analyst)
Summary
Adds (sums) the values of two rasters on a cell-by-cell basis.

Plus_3d (InRas1, InRas2, OutRas) |
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.
Syntax
| Parameter | Explanation | Data Type |
in_raster_or_constant1 |
The input whose values will be added to. 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 will be added to 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 |
out_raster |
The output raster. The cell values are the sum of the first input added to the second. | Raster Dataset |
Code Sample
This example adds the values of two GRID rasters and outputs the result as a GRID raster.
import arcpy
from arcpy import env
env.workspace = "C:/data"
arcpy.Plus_3d("elevation", 15, "C:/output/outplus.img")
