Summary
Creates a raster object by extracting one or more bands from, or reordering the bands in, a multiband raster.
Discussion
For more information about how this function works, see the Extract Bands raster function.
The referenced raster dataset for the raster object is temporary. To make it permanent, you can call the raster object's save method.
Syntax
ExtractBand (raster, {band_ids}, {band_names}, {band_wavelengths}, {missing_band_action}, {wavelength_match_tolerance})
Parameter | Explanation | Data Type |
raster | The input raster. | Raster |
band_ids [band_ids,...] | Extracts bands using the band ID. (The default value is None) | Integer |
band_names [band_names,...] | Extracts bands using the name of the bands. (The default value is None) | String |
band_wavelengths [band_wavelengths,...] | Extracts bands using the band wavelengths. (The default value is None) | Double |
missing_band_action | Specifies the action that will occur when a band within the extract band list is not available.
(The default value is BestMatch) | Integer |
wavelength_match_tolerance | Specifies the margin of error when extracting bands using the band_wavelengths method. (The default value is None) | Double |
Data Type | Explanation |
Raster | The output raster. |
Code sample
Extracts bands from the input raster using the band_ids method.
import arcpy
out_bands_raster = arcpy.sa.ExtractBand("in_raster.tif", [1, 2])
Extracts bands from the input raster using the band_wavelengths method.
import arcpy
out_bands_raster = arcpy.sa.ExtractBand("in_raster.tif", band_wavelengths=[500.00])
