momepy.Blocks(tessellation, edges, buildings, id_name, unique_id)[source]¶Generate blocks based on buildings, tesselation and street network
Captures bID to buildings and tesselation as attributes.
GeoDataFrame containing morphological tessellation
GeoDataFrame containing street network
GeoDataFrame containing buildings
name of the unique blocks id column to be generated
name of the column with unique id. If there is none, it could be generated by unique_id(). This should be the same for cells and buildings, id’s should match.
