momepy.PerimeterWall¶

class momepy.PerimeterWall(gdf, spatial_weights=None)[source]¶

Calculate the perimeter wall length the joined structure.

Parameters

gdfGeoDataFrame

GeoDataFrame containing objects to analyse

spatial_weightslibpysal.weights, optional

spatial weights matrix - If None, Queen contiguity matrix will be calculated based on gdf. It is to denote adjacent buildings (note: based on index, not ID).

Notes

It might take a while to compute this character.

Examples

>>> buildings_df['wall_length'] = mm.PerimeterWall(buildings_df).series
