🧮 Controlling the RGB Bands

The ipyleaflet and folium tile layer utilities support setting which bands to view as the RGB channels. To set the RGB bands, pass a length three list of the band indices to the band argument.

Here is an example where I create two tile layers from the same raster but viewing a different set of bands:

from localtileserver import get_leaflet_tile_layer, examples
from ipyleaflet import Map, ScaleControl, FullScreenControl, SplitMapControl

# First, create TileClient using example file
client = examples.get_landsat()

client.thumbnail(band=[7, 5, 4])

client.thumbnail(band=[5, 3, 2])

# Create 2 tile layers from same raster viewing different bands
l = get_leaflet_tile_layer(client, band=[7, 5, 4])
r = get_leaflet_tile_layer(client, band=[5, 3, 2])

# Make the ipyleaflet map
m = Map(center=client.center(), zoom=client.default_zoom)
control = SplitMapControl(left_layer=l, right_layer=r)
m.add_control(control)
m.add_control(ScaleControl(position='bottomleft'))
m.add_control(FullScreenControl())
m

Additionally, localtileserver supports a full styling specification from large-image for more complex composite images.

See https://girder.github.io/large_image/tilesource_options.html#style

from localtileserver import get_leaflet_tile_layer, examples
from ipyleaflet import Map

client = examples.get_landsat()

style = {
  'bands': [
    {'band': 5, 'palette': '#f00'},
    {'band': 3, 'palette': '#0f0'},
    {'band': 2, 'palette': '#00f'},
  ]
}

client.thumbnail(style=style)

l = get_leaflet_tile_layer(client, style=style)

m = Map(center=client.center(), zoom=client.default_zoom)
m.add_layer(l)
m
