Adding a GeoPandas GeoDataFrame to the map with a single line of code

Uncomment the following line to install leafmap if needed. You can also use conda to create a new environment to install geopandas and leafmap.

conda create geo -n python=3.8
conda activate geo
conda install geopandas
conda install mamba -c conda-forge
mamba install leafmap -c conda-forge

Use GeoPandas to read a GeoJSON from an HTTP URL and return it as a GeoDataFrame.

Sample data: https://github.com/opengeos/leafmap/raw/master/examples/data/cable_geo.geojson

In [5]:

gdf = gpd.read_file(
    "https://github.com/opengeos/leafmap/raw/master/examples/data/cable_geo.geojson"
)

gdf = gpd.read_file( "https://github.com/opengeos/leafmap/raw/master/examples/data/cable_geo.geojson" )

Add a GeoDataFrame to the map.

In [6]:

m = leafmap.Map()
m.add_gdf(gdf, layer_name="Cable lines")
m

m = leafmap.Map() m.add_gdf(gdf, layer_name="Cable lines") m
