Popularity

サマリー

Creates a raster object in which each pixel contains the value in an argument list that is at a certain level of popularity.

説明

For more information about how this function works, see the Popularity 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

Popularity (popularity_raster, rasters, {extent_type}, {cellsize_type}, {process_as_multiband})

パラメーター	説明	データ タイプ
popularity_raster	The input raster that defines the popularity position to be returned.	Raster
rasters [rasters,...]	The list of input rasters.	Raster
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
process_as_multiband	Specifies how the bands of the input rasters will be processed. True—Each multiband raster will be processed as a multiband raster. The operation will be performed for each band from one input using the corresponding band number from other inputs. False—Each band from a multiband raster input will be processed separately as a single-band raster. (デフォルト値は次のとおりです False)	Boolean

戻り値

データ タイプ	説明
Raster	The output raster.

コードのサンプル

Popularity example

Calculates the values in the set of input rasters that reach the specified level of popularity.

# Import system modules
import arcpy
from arcpy.ia import *

#Set the local variables
popularity_raster = r"c:\temp\value_raster.tif"

rasters = [r"c:\temp\raster1.tif", r"c:\temp\raster2.tif", r"c:\temp\raster3.tif"] 

#Execute
output_raster = Popularity(popularity_raster, rasters, "UnionOf", "FirstOf", True)
