HighestPosition

サマリー

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

説明

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.

構文

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

パラメーター	説明	データ タイプ
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 will be defined using the extent of the first input raster. LastOf—The output extent will be defined using the extent of the last input raster. IntersectionOf—The output extent will be defined as the intersecting area of the input rasters. UnionOf—The output extent will be defined as the total extent of the input rasters. (デフォルト値は次のとおりです 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 will be defined using the pixel size of the first input raster. LastOf—The output pixel size will be defined using the pixel size of the last input raster. MaxOf—The output pixel size will be defined using the maximum pixel size of the input rasters. MeanOf—The output pixel size will be defined using the mean of both input rasters. MinOf—The output pixel size will be defined using the minimum pixel size of the input rasters. (デフォルト値は次のとおりです FirstOf)	String

戻り値

データ タイプ	説明
Raster	The output raster.

コードのサンプル

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")
