Resumen
Creates a raster object by extracting one or more bands from, or reordering the bands in, a multiband raster.
Debate
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.
Sintaxis
ExtractBand (raster, {band_ids}, {band_names}, {band_wavelengths}, {missing_band_action}, {wavelength_match_tolerance})
Parámetro | Explicación | Tipo de datos |
raster | The input raster. | Raster |
band_ids [band_ids,...] | Extracts bands using the band ID. (El valor predeterminado es None) | Integer |
band_names [band_names,...] | Extracts bands using the name of the bands. (El valor predeterminado es None) | String |
band_wavelengths [band_wavelengths,...] | Extracts bands using the band wavelengths. (El valor predeterminado es None) | Double |
missing_band_action | Specifies the action that will occur when a band within the extract band list is not available.
(El valor predeterminado es BestMatch) | Integer |
wavelength_match_tolerance | Specifies the margin of error when extracting bands using the band_wavelengths method. (El valor predeterminado es None) | Double |
Tipo de datos | Explicación |
Raster | The output raster. |
