Zusammenfassung
Creates a raster object by unpacking the bits of the input pixel and mapping them to specified bits in the output pixel. The purpose of this function is to manipulate bits from a couple of inputs, such as the Landsat 8 quality band products.
Auswertung
For more information about how this function works, see the Transpose Bits 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
TransposeBits (raster, {input_bit_positions}, {output_bit_positions}, {constant_fill_value}, {fill_raster})| Parameter | Erklärung | Datentyp |
raster | The input raster to unpack and remap. | Raster |
input_bit_positions [input_bit_positions,...] | The list of input bits. (Der Standardwert ist [12, 13]) | Integer |
output_bit_positions [output_bit_positions,...] | The list of output bits. (Der Standardwert ist [0, 1]) | Integer |
constant_fill_value | An integer used to fill in all bits that are not involved in the transpose. (Der Standardwert ist 0) | Integer |
fill_raster | A raster used to fill in all bits that are not involved in the transpose. (Der Standardwert ist None) | Raster |
| Datentyp | Erklärung |
| Raster | The output raster. |
Codebeispiel
Remaps the bits from the input raster to the Landsat 8 Water bit pattern.
import acrpy
transpose_raster = arcpy.ia.TransposeBits("Landsat_8.tif",[4, 5],[0, 1], 0, None)
