Summary
Creates a raster object in which each pixel contains the position of the raster with the maximum value in a set of rasters.
Discussion
For more information about how this function works, see the Highest Position tool.
The referenced raster dataset for the raster object is temporary. To make it permanent, you can call the raster object's save method.
Syntax
HighestPosition (rasters, {extent_type}, {cellsize_type})
Parameter | Explanation | Data Type |
rasters [rasters,...] |
The list of input rasters. | None |
extent_type | The method that will be used to compute the extent of the output when the input rasters have different extents.
(The default value is FirstOf) | String |
cellsize_type | The method that will be used to compute the pixel size of the output when the input rasters have different pixel sizes.
(The default value is FirstOf) | String |
Data Type | Explanation |
Raster |
The output raster. |
Code sample
Calculates the raster with the maximum value in a set of input rasters.
# Import system modules
import arcpy
from arcpy.ia import *
#Set the local variables
rasters = [r"c:\temp\raster1.tif", r"c:\temp\raster2.tif", r"c:\temp\raster3.tif"]
#Execute
Highest_raster = HighestPosition(rasters, "UnionOf", "FirstOf")
