MapFlyer - manywidgets

Buttons that animate a lonboard Map to preset locations, driving lonboard’s fly_to from the browser.

Each preset is a dict with a label and deck.gl camera keys (longitude, latitude, zoom, and optionally pitch / bearing). Clicking a button flies the map there — no kernel required, so it behaves the same live and in static export.

Import¶

from manywidgets.lonboard import MapFlyer

Example¶

from lonboard import Map, ScatterplotLayer
from manywidgets.lonboard import MapFlyer

layer = ScatterplotLayer.from_geopandas(gdf)
m = Map(layer, basemap=None)
flyer = MapFlyer(m, locations=[
    {"label": "New York", "longitude": -74.0, "latitude": 40.7, "zoom": 10},
    {"label": "London", "longitude": -0.12, "latitude": 51.5, "zoom": 9},
], duration=3000)

# show the control and the map together (see the Layout widgets)
from manywidgets import Column
Column(flyer, m)
