Car route Example

Calculate car route between origin and destination.

import os

from here_location_services import LS
from here_location_services.config.routing_config import ROUTING_RETURN
from here_map_widget import Map, Marker, GeoJSON

LS_API_KEY = os.environ.get("LS_API_KEY")  # Get API KEY from environment.
ls = LS(api_key=LS_API_KEY)

result = ls.car_route(
    origin=[52.51375, 13.42462],
    destination=[52.52332, 13.42800],
    return_results=[
        ROUTING_RETURN.polyline,
        ROUTING_RETURN.elevation,
        ROUTING_RETURN.instructions,
        ROUTING_RETURN.actions,
    ],
)
geo_json = result.to_geojson()
data = geo_json
geo_layer = GeoJSON(data=data, style={"lineWidth": 5})

m = Map(api_key=LS_API_KEY, center=[52.5207, 13.4283], zoom=14)
origin_marker = Marker(lat=52.51375, lng=13.42462)

m.add_layer(geo_layer)
m.add_object(origin_marker)
m.add_object(dest_marker)
