- momepy.get_network_ratio(df, edges, initial_buffer=500)[source]#
Link polygons to network edges based on the proportion of overlap (if a cell intersects more than one edge). Useful if you need to link enclosed tessellation to street network. Ratios can be used as weights when linking network-based values to cells. For a purely distance-based link use
momepy.get_network_id(). Links are based on the integer position of edge (
A GeoDataFrame containing objects to snap (typically enclosed tessellation).
A GeoDataFrame containing a street network.
The initial buffer used to link non-intersecting cells.
The resultant DataFrame.
