momepy.enclosures¶

momepy.enclosures(primary_barriers, limit=None, additional_barriers=None, enclosure_id='eID')[source]¶

Generate enclosures based on passed barriers.

Enclosures are areas enclosed from all sides by at least one type of a barrier. Barriers are typically roads, railways, natural features like rivers and other water bodies or coastline. Enclosures are a result of polygonization of the primary_barrier and limit and its subdivision based on additional_barriers.

Parameters

primary_barriersGeoDataFrame, GeoSeries: GeoDataFrame or GeoSeries containing primary barriers. (Multi)LineString geometry is expected.
limitGeoDataFrame, GeoSeries (default None): GeoDataFrame or GeoSeries containing external limit of enclosures, i.e. the area which gets partitioned. If None is passed, the internal area of primary_barriers will be used.
additional_barriersGeoDataFrame: GeoDataFrame or GeoSeries containing additional barriers. (Multi)LineString geometry is expected.
enclosure_idstr (default ‘eID’): name of the enclosure_id (to be created).

Returns

enclosuresGeoDataFrame: GeoDataFrame containing enclosure geometries and enclosure_id

Examples

>>> enclosures = mm.enclosures(streets, admin_boundary, [railway, rivers])
