Resumen
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.
Debate
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.
Sintaxis
TransposeBits (raster, {input_bit_positions}, {output_bit_positions}, {constant_fill_value}, {fill_raster})
Parámetro | Explicación | Tipo de datos |
raster | The input raster to unpack and remap. | Raster |
input_bit_positions [input_bit_positions,...] | The list of input bits. (El valor predeterminado es [12, 13]) | Integer |
output_bit_positions [output_bit_positions,...] | The list of output bits. (El valor predeterminado es [0, 1]) | Integer |
constant_fill_value | An integer used to fill in all bits that are not involved in the transpose. (El valor predeterminado es 0) | Integer |
fill_raster | A raster used to fill in all bits that are not involved in the transpose. (El valor predeterminado es None) | Raster |
Tipo de datos | Explicación |
Raster | The output raster. |
