Globe control

Add a globe control to the map

Uncomment the following line to install leafmap if needed.

In [ ]:

# %pip install "leafmap[maplibre]"

# %pip install "leafmap[maplibre]"

Import library¶

In [ ]:

import leafmap.maplibregl as leafmap

import leafmap.maplibregl as leafmap

To run this notebook, you will need an API key from MapTiler. Once you have the API key, you can uncomment the following code block and replace YOUR_API_KEY with your actual API key. Then, run the code block code to set the API key as an environment variable.

In [ ]:

# import os
# os.environ["MAPTILER_KEY"] = "YOUR_API_KEY"

# import os # os.environ["MAPTILER_KEY"] = "YOUR_API_KEY"

Add globe control¶

In [ ]:

m = leafmap.Map(center=[-100, 40], zoom=3, style="liberty")
m.add_globe_control()
m

m = leafmap.Map(center=[-100, 40], zoom=3, style="liberty") m.add_globe_control() m

Use globe projection¶

In [ ]:

m = leafmap.Map(center=[-100, 40], zoom=3, style="basic", projection="globe")
m.add_overture_3d_buildings()
m

m = leafmap.Map(center=[-100, 40], zoom=3, style="basic", projection="globe") m.add_overture_3d_buildings() m

In [ ]:

m = leafmap.Map(center=[-100, 40], zoom=3, style="3d-hybrid", projection="globe")
m

m = leafmap.Map(center=[-100, 40], zoom=3, style="3d-hybrid", projection="globe") m
