maplibregl module

The maplibregl module provides the Map class for creating interactive maps using the maplibre.ipywidget module.

Map (MapWidget)

The Map class inherits from the MapWidget class of the maplibre.ipywidget module.

add_geojson(self, data, layer_type=None, filter=None, paint=None, name=None, fit_bounds=True, visible=True, before_id=None, source_args={}, **kwargs)

Adds a GeoJSON layer to the map.

This method adds a GeoJSON layer to the map. The GeoJSON data can be a URL to a GeoJSON file or a GeoJSON dictionary. If a name is provided, it is used as the key to store the layer in the layer dictionary. Otherwise, a random name is generated.

Parameters:

Name Type Description Default
data str | dict

The GeoJSON data. This can be a URL to a GeoJSON file or a GeoJSON dictionary.

required
layer_type str

The type of the layer. It can be one of the following: 'circle', 'fill', 'fill-extrusion', 'line', 'symbol', 'raster', 'background', 'heatmap', 'hillshade'. If None, the type is inferred from the GeoJSON data.

None
filter dict

The filter to apply to the layer. If None, no filter is applied.

None
paint dict

The paint properties to apply to the layer. If None, no paint properties are applied.

None
name str

The name of the layer. If None, a random name is generated.

None
fit_bounds bool

Whether to adjust the viewport of the map to fit the bounds of the GeoJSON data. Defaults to True.

True
visible bool

Whether the layer is visible or not. Defaults to True.

True
before_id str

The ID of an existing layer before which the new layer should be inserted.

None
source_args dict

Additional keyword arguments that are passed to the GeoJSONSource class.

{}
**kwargs Any

Additional keyword arguments that are passed to the Layer class. See https://maplibre.org/maplibre-style-spec/layers/ for more info.
