Summary
Creates a raster object in which each pixel contains the median value across multiple rasters.
Syntax
Median (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
Calculates the median value across three multiband rasters.
from arcpy.ia import *
rc = RasterCollection([landsat_1, landsat_2, landsat_3])
mean_raster = Median(rc, extent_type = "UnionOf", cellsize_type = "MinOf",
ignore_nodata = True, process_as_multiband = True)
