import leafmap.deck as leafmap

Create an interactive map.

In [3]:

m = leafmap.Map(center=(40, -100), zoom=3)
m

m = leafmap.Map(center=(40, -100), zoom=3) m

Out[3]:

Add basemap.

In [4]:

m = leafmap.Map()
m.add_basemap("OpenTopoMap")
m

m = leafmap.Map() m.add_basemap("OpenTopoMap") m

Out[4]:

Add vector data to the map. It supports any GeoPandas supported format, such as GeoJSON, shapefile, KML.

In [5]:

m = leafmap.Map()
filename = (
    "https://github.com/giswqs/streamlit-geospatial/raw/master/data/us_states.geojson"
)
m.add_vector(filename, random_color_column="STATEFP")
m

m = leafmap.Map() filename = ( "https://github.com/giswqs/streamlit-geospatial/raw/master/data/us_states.geojson" ) m.add_vector(filename, random_color_column="STATEFP") m

Out[5]:

Add a GeoPandas GeoDataFrame to the map.

In [6]:

import geopandas as gpd

url = (
    "https://github.com/giswqs/streamlit-geospatial/raw/master/data/us_counties.geojson"

In [8]:
