TransposeBits

サマリー

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.

説明

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.

コードのサンプル

TransposeBits example

Remaps the bits from the input raster to the Landsat 8 Water bit pattern.

import acrpy

transpose_raster = arcpy.sa.TransposeBits("Landsat_8.tif",[4, 5],[0, 1], 0, None)
