Synthèse
Creates a raster object in which each pixel contains the value that occurs least often across multiple rasters.
Discussion
The referenced raster dataset for the raster object is temporary. To make it permanent, you can call the raster object's save method.
Syntaxe
Minority (rasters, {extent_type}, {cellsize_type}, {ignore_nodata}, {process_as_multiband})
Paramètre | Explication | Type de données |
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.
(La valeur par défaut est 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.
(La valeur par défaut est FirstOf) | String |
ignore_nodata | Specifies whether NoData values will be ignored in the calculation.
(La valeur par défaut est False) | Boolean |
process_as_multiband | Specifies how the bands of the input rasters will be processed.
(La valeur par défaut est False) | Boolean |
Type de données | Explication |
Raster | The output raster. |
Exemple de code
Calculates the value that occurs least often across three multiband rasters.
from arcpy.ia import *
rc = RasterCollection([landsat_1, landsat_2, landsat_3])
minority_raster = Minority(rc, extent_type = "UnionOf", cellsize_type = "MinOf",
ignore_nodata = True, process_as_multiband = True)
