Folium

paket Python
peta interaktif
dibangun di atas Leaflet.js

folium.Map()

import folium
# construct a map centered at the Eiffel Tower
eiffel_tower = folium.Map(location = [48.8583736,2.2922926])

# display the map
display(eiffel_tower)

Lokasi Folium dari centroid

# reverse the order for folium location array
district_center = [center_point.y, center_point.x]

# print center point and district_center
print(center_point)
print(district_center)

Menambahkan poligon ke peta folium

# create a folium map centered on district 1
district1_map = folium.Map(location = district_center)

# add the outline of district one
folium.GeoJson(district_one.geometry).add_to(district1_map)

# display the resulting map
display(district1_map)
