Summary
Creates a raster object in which each pixel contains the difference between the largest and smallest values 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.
Syntax
Range (rasters, {extent_type}, {cellsize_type}, {ignore_nodata}, {process_as_multiband})
Parameter | Explanation | Data Type |
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.
(The default value is 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.
(The default value is FirstOf) | String |
ignore_nodata | Specifies whether NoData values will be ignored in the calculation.
(The default value is False) | Boolean |
process_as_multiband | Specifies how the bands of the input rasters will be processed.
(The default value is False) | Boolean |
Data Type | Explanation |
Raster | The output raster. |
Code sample
Computes a raster object that contains the difference between the largest and smallest values across three multiband rasters.
from arcpy.ia import *
rc = RasterCollection([landsat_1, landsat_2, landsat_3])
range_raster = Range(rc, extent_type = "UnionOf", cellsize_type = "MinOf",
ignore_nodata = True, process_as_multiband = True)
