Zusammenfassung
Creates a raster object in which each pixel contains the minimum value across multiple rasters.
Diskussion
The referenced raster dataset for the raster object is temporary. To make it permanent, you can call the raster object's save method.
Syntax
Min (rasters, {extent_type}, {cellsize_type}, {ignore_nodata}, {process_as_multiband})
Parameter | Erläuterung | Datentyp |
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.
(Der Standardwert ist 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.
(Der Standardwert ist FirstOf) | String |
ignore_nodata | Specifies whether NoData values will be ignored in the calculation.
(Der Standardwert ist False) | Boolean |
process_as_multiband | Specifies how the bands of the input rasters will be processed.
(Der Standardwert ist False) | Boolean |
Datentyp | Erläuterung |
Raster | The output raster. |
Codebeispiel
Calculates the minimum value that occurs across three multiband rasters.
from arcpy.ia import *
rc = RasterCollection([landsat_1, landsat_2, landsat_3])
min_raster = Min(rc, extent_type = "UnionOf", cellsize_type = "MinOf",
ignore_nodata = True, process_as_multiband = True)
