Zusammenfassung
Creates a raster object by extracting one or more bands from, or reordering the bands in, a multiband raster.
Auswertung
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 | Erklärung | Datentyp |
raster | The input raster. | Raster |
band_ids [band_ids,...] | Extracts bands using the band ID. (Der Standardwert ist None) | Integer |
band_names [band_names,...] | Extracts bands using the name of the bands. (Der Standardwert ist None) | String |
band_wavelengths [band_wavelengths,...] | Extracts bands using the band wavelengths. (Der Standardwert ist None) | Double |
missing_band_action | Specifies the action that will occur when a band within the extract band list is not available.
(Der Standardwert ist BestMatch) | Integer |
wavelength_match_tolerance | Specifies the margin of error when extracting bands using the band_wavelengths method. (Der Standardwert ist None) | Double |
Datentyp | Erklärung |
Raster | The output raster. |
Codebeispiel
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])
