HeatMap Layer

Heat Map is an here-map-widget-for-jupyter class that allows you to generate a Heat Map for your data.

Example

from random import uniform
from here_map_widget import TileLayer, HeatMap
from here_map_widget import Map
import os

data = [[uniform(-80, 80), uniform(-180, 180), uniform(0, 1000)] for i in range(1000)]

heat_map_data = []
for row in data:
    heat_map_data.append({"lat": row[0], "lng": row[1], "value": row[2]})

m = Map(api_key=os.environ["LS_API_KEY"])
provider = HeatMap(interpolate=True, opacity=0.6, assume_values=True)
provider.add_data(heat_map_data)
heatmap = TileLayer(provider=provider)
m.add_layer(heatmap)
m

Attributes

Attribute	Type	Doc
colors	dict	An dict object defining the color stops for example {‘0.0’: ‘blue’, ‘0.5’: ‘yellow’, ‘1’: ‘red’}
interpolate	boolean	A value indicating whether interpolation is to be used to display smooth color transitions in the heat map
opacity	float	The opacity which is used for the rendering of the heatmap in range [0..1]
assume_values	boolean	A Boolean value indicating whether to paint assumed values in regions where no data is available
data	list	Data list which is used to generate heat map
hardReload	boolean	A value indicating whether to invalidate in hard mode (True) or in soft mode (False) while adding data
