๐Ÿš€ User Guide#

localtileserver can be used in a few different ways:

  • In a Jupyter notebook with ipyleaflet or folium

  • From the commandline in a web browser

  • With remote Cloud Optimized GeoTiffs

Here is the โ€œone-linerโ€ to visualize a large geospatial image with ipyleaflet in Jupyter:

from localtileserver import TileClient, examples

# client = TileClient('path/to/geo.tif')
client = examples.get_san_francisco()  # use example data

The localtileserver.TileClient class utilizes the _ipython_display_ method to automatically display the tiles with ipyleaflet in a Notebook.

๐Ÿƒ ipyleaflet Tile Layers#

The TileClient class is a nifty tool to launch a tile server as a background thread to serve image tiles from any raster file on your local file system. Additionally, it can be used in conjunction with the get_leaflet_tile_layer() utility to create an ipyleaflet.TileLayer for interactive visualization in a Jupyter notebook. Here is an example:

from localtileserver import get_leaflet_tile_layer, TileClient, examples
from ipyleaflet import Map

# First, create a tile server from local raster file
# client = TileClient('path/to/geo.tif')
client = examples.get_elevation()  # use example data

# Create ipyleaflet tile layer from that server
t = get_leaflet_tile_layer(client,
                           band=1, vmin=-5000, vmax=5000, palette='cmo.topo',

# Create ipyleaflet map, add tile layer, and display
m = Map(zoom=3)

๐ŸŒณ folium Tile Layers#

Similarly to the support provided for ipyleaflet, I have included a utility to generate a folium.TileLayer (see reference) with get_folium_tile_layer(). Here is an example with almost the exact same code as the ipyleaflet example, just note that folium.Map is imported from folium and we use add_child() instead of add_layer():

from localtileserver import get_folium_tile_layer, TileClient, examples
from folium import Map

# First, create a tile server from local raster file
# client = TileClient('path/to/geo.tif')
client = examples.get_oam2()  # use example data

# Create folium tile layer from that server
t = get_folium_tile_layer(client)

m = Map(location=client.center(), zoom_start=16)
Make this Notebook Trusted to load map: File -> Trust Notebook

๐Ÿ—’๏ธ Usage Notes#

  • get_leaflet_tile_layer() accepts either an existing TileClient or a path from which to create a TileClient under the hood.

  • The color palette choices come from palettable.

  • If matplotlib is installed, any matplotlib colormap name cane be used a palette choice
