HighestPosition

Resumen

Creates a raster object where each pixel contains the position of the raster with the maximum value in a set of rasters.

Debate

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.

Sintaxis

HighestPosition (rasters, {extent_type}, {cellsize_type})

Parámetro	Explicación	Tipo de datos
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. FirstOf—The output extent is defined using the extent of the first input raster. LastOf—The output extent is defined using the extent of the last input raster. IntersectionOf—The output extent is defined as the intersecting area of the input rasters. UnionOf—The output extent is defined as the total extent of the input rasters. (El valor predeterminado es 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. FirstOf—The output pixel size is defined using the pixel size of the first input raster. LastOf—The output pixel size is defined using the pixel size of the last input raster. MaxOf—The output pixel size is defined using the maximum pixel size of the input rasters. MeanOf—The output pixel size is defined using the mean of both input rasters. MinOf—The output pixel size is defined using the minimum pixel size of the input rasters. (El valor predeterminado es FirstOf)	String

Valor de retorno

Tipo de datos	Explicación
Raster	The output raster.

HighestPosition example

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")
