xlandsat.pansharpen

xlandsat.pansharpen(scene, panchromatic, weights=(1, 1, 0.2))

Pansharpen the red, green, and blue bands of a scene.

The pansharpened scene will have the same coordinate values of the given panchromatic band. Uses a weighted version of the Brovey Transform [Pohl_and_VanGenderen1998] to account for the smaller blue footprint in Landsat 8/9 panchromatic band, following mapbox/rio-pansharpen (MIT license).

Parameters:

• scene (xarray.Dataset) – A Landsat scene, as read with xlandsat.load_scene. The scene must contain the red, green, and blue bands. Other bands are ignored.

• panchromatic (xarray.DataArray) – A Landsat panchromatic band, as read with xlandsat.load_panchromatic.

• weights (tuple) – The weights applied to the red, green, and blue bands, respectively.

Returns:

scene_sharpened (xarray.Dataset) – The pandsharpened scene including the red, green, and blue bands only. Metadata from the original scene is copied into the pandsharpened version.
