momepy.Blocks#
- class momepy.Blocks(tessellation, edges, buildings, id_name, unique_id, **kwargs)[source]#
Generate blocks based on buildings, tessellation, and street network.
Dissolves tessellation cells based on street-network based polygons. Links resulting id to
buildingsandtessellationas attributes.- Parameters
- tessellationGeoDataFrame
GeoDataFrame containing morphological tessellation
- edgesGeoDataFrame
GeoDataFrame containing street network
- buildingsGeoDataFrame
GeoDataFrame containing buildings
- id_namestr
name of the unique blocks id column to be generated
- unique_idstr
name of the column with unique id. If there is none, it could be generated by
momepy.unique_id(). This should be the same for cells and buildings, id’s should match.
Examples
>>> blocks = mm.Blocks(tessellation_df, streets_df, buildings_df, 'bID', 'uID') >>> blocks.blocks.head() bID geometry 0 1.0 POLYGON ((1603560.078648818 6464202.366899694,... 1 2.0 POLYGON ((1603457.225976106 6464299.454696888,... 2 3.0 POLYGON ((1603056.595487018 6464093.903488506,... 3 4.0 POLYGON ((1603260.943782872 6464141.327631323,... 4 5.0 POLYGON ((1603183.399594798 6463966.109982309,...
