GeoPandas¶

GeoPandas extends the Pandas data frame library to allow spatial operations on geospatial data.

All relevant Lonboard layer classes have a from_geopandas method for GeoDataFrame input.

Some layer types, such as BitmapLayer, don't have a from_geopandas method because the rendering isn't relevant to GeoPandas (i.e. GeoPandas doesn't store image data).

Example¶

import geodatasets
import geopandas as gpd
from lonboard import Map, SolidPolygonLayer

# New York City boroughs
gdf = gpd.read_file(geodatasets.get_path('nybb'))
layer = SolidPolygonLayer.from_geopandas(
    gdf,
    get_fill_color=[255, 0, 0],
)
m = Map(layer)
