momepy.get_network_ratio¶

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_nearest_street(). Links are based on the integer position of edge (iloc).

Parameters:¶

df : GeoDataFrame¶

A GeoDataFrame containing objects to snap (typically enclosed tessellation).

edges : GeoDataFrame¶

A GeoDataFrame containing a street network.

initial_buffer : float¶

The initial buffer used to link non-intersecting cells.

Returns:¶

result – The resultant DataFrame.

Return type:¶

DataFrame
